# Changelog
|
|
|
|
This document outlines major changes between releases.
|
|
|
|
## 0.103.1 "Verification" (09 Nov 2023)
|
|
|
|
An urgent 3.6.0-compatible version that contains a hotfix for the bug that
|
|
prevents node from starting from the existing database every new dBFT epoch.
|
|
Also, the release includes a bugfix that fails any non-zero NEO and GAS
|
|
roundtrips from accounts with zero balance.
|
|
|
|
Although the DB format and storage states were not affected by this release,
|
|
the node resynchronization is still recommended for those who want to keep
|
|
correct application logs. Resynchronization can be skipped if you're ok with
|
|
wrong application logs for some transactions (e.g. CN doesn't care, and RPC node
|
|
cares a lot).
|
|
|
|
Bugs fixed:
|
|
* properly initialize cache of native NeoToken contract every new dBFT epoch (#3187)
|
|
* forbid non-zero NEO and GAS roundtrips from accounts with zero balance (#3191)
|
|
|
|
## 0.103.0 "Backwardation" (20 Oct 2023)
|
|
|
|
A minor 3.6.0-compatible version of NeoGo with new salty ZKP-related
|
|
functionality, a large batch of deprecated APIs removal and an experimental
|
|
genesis block extension. Build Groth-16 circuits, generate proofs and deploy
|
|
verification contracts easily with the new end-to-end ZKP example and `zkpbinding`
|
|
NeoGo API. Setup node roles via the node configuration starting from the genesis
|
|
block without any painful multisignature transaction forming and invoke any
|
|
custom script in the genesis-level transaction with the new `Genesis` protocol
|
|
configuration extension. And don't forget to move from deprecated RPC client
|
|
APIs, as a lot of them have been removed.
|
|
|
|
New node configuration format is finally adapted and the deprecated configuration
|
|
sections are permanently removed according to the schedule. Pay attention to the
|
|
`SecondsPerBlock` protocol configuration section that was replaced by
|
|
`TimePerBlock`, a set of node and services address- and port- related configuration
|
|
section that were replaced by the new `Addresses` format, direct `UnlockWallet`
|
|
consensus configuration that was replaced by a separate `Consensus` section and
|
|
a set of node-specific protocol configurations that were moved under a separate
|
|
`P2P` section.
|
|
|
|
This release fixes a set of bugs including a vulnerability introduced by changes
|
|
in the transaction conflicts storage scheme implemented in #3061 (a part of
|
|
0.102.0 release). With the patch presented, it's impossible to uncontrollably
|
|
pollute the storage with malicious conflicting records.
|
|
|
|
This version is fully compatible with C# node 3.6.0. However, it requires
|
|
complete resynchronization on upgrade due to the database storage scheme changes.
|
|
|
|
New features:
|
|
* API for Groth-16 verification contracts autogeneration and end-to-end example for
|
|
proving and verifying statements on NeoGo (#3043, #3146)
|
|
* introduce genesis protocol extensions: default node roles designation and genesis
|
|
transactions (#3168)
|
|
|
|
Behaviour changes:
|
|
* a lot of deprecated functionality is dropped: RPC client old APIs, shared
|
|
Notifications channel of WebSocket client, SecondsPerBlock protocol
|
|
configuration, old way of services and node address and port configuration, old
|
|
P2P related application settings configuration, direct UnlockWallet consensus
|
|
configuration, direct node-specific protocol configuration (#3150)
|
|
* database scheme is changed by new way of storing the transaction conflicting
|
|
records (#3138)
|
|
|
|
Improvements:
|
|
* NeoFS SDK dependency upgrade (#3129)
|
|
* gnark and gnark-crypto dependencies upgrade (#3145, #3162, #3163)
|
|
* introduce timeout restriction for BoltDB opening (#3148)
|
|
* bump code coverage uploading action version (#3153)
|
|
* Go 1.21 support, bump minimum required Go version up to Go 1.19 (#3157)
|
|
* upgrade golang.org/x/net version (#3158)
|
|
* add protocol hardforks configuration to the `getversion` RPC response (#3160)
|
|
* format autogenerated smart contract bindings with accordance to standard `go fmt` rules (#3164)
|
|
* add "DO NOT EDIT" warning to the autogenerated smart contract bindings (#3167)
|
|
|
|
Bugs fixed:
|
|
* avoid race between `getnextblockvalidators` RPC call handler and blockchain's
|
|
block handler routine, significantly refactor native validators caching scheme
|
|
(#3110)
|
|
* do not panic on failed NeoFS oracle requests (#3129)
|
|
* enable Notary subsystem in NeoFS mainnet configuration (#3136)
|
|
* reorganize storage scheme for transaction conflicting records to avoid possible attack (#3138)
|
|
* properly deserialize wildcard trusts field of smart contract manifest (#3140)
|
|
* use more strict GAS limit for transaction network fee calculation via RPC call (#3141)
|
|
* avoid WebSocket client request blocking (#3142)
|
|
* properly emit big uint64 constants during smart contract compilation (#3147)
|
|
* avoid race access to the node version by tests (#3149)
|
|
* make FindStorage* RPC client APIs to be always compatible with NeoC# RPC server (#3166)
|
|
|
|
## 0.102.0 "Aberration" (06 Sep 2023)
|
|
|
|
Long-awaited feature-packed 3.6.0-compatible version of NeoGo with all the
|
|
appropriate protocol updates and a set of tasty improvements and bug
|
|
fixes. Groth16 ZKP proof checks are there for contract developers as well as
|
|
new opcodes. A huge number of improvements went into the RPC server and
|
|
client, new RPCs, improved contract binding generator and standardized
|
|
extended error codes make developing dApps much easier.
|
|
|
|
Users of smart contract utilities and RPC-related Prometheus metrics are
|
|
advised to take a look at the deprecated APIs removal schedule
|
|
(ROADMAP.md). This version was delayed for quite some time (waiting for 3.6),
|
|
so the next minor release (0.103.0) will remove a substantial amount of
|
|
compatibility code. It's expected to be released in November with 3.6 protocol
|
|
compatibility (3.7 cycle is likely to require more time).
|
|
|
|
This is also the first version that drops support for Go 1.17 and requires
|
|
1.18+ to build (with Go 1.20 supported). Using generics in smart contracts is
|
|
not supported yet, but some elements of this support can be implemented in
|
|
future versions.
|
|
|
|
Mainnet and testnet node operators, please pay attention to the Basilisk
|
|
hardfork schedule and check your configurations. It will happen at block
|
|
2680000 for T5 testnet and 4120000 for mainnet. To ensure compatibility your
|
|
node must be configured appropriately. This version requires DB
|
|
resynchronization, so schedule your updates accordingly.
|
|
|
|
New features:
|
|
* ZKP proof checking support via CryptoLib native contract (operations with
|
|
BLS12-381 curve points) (#2940, #3042)
|
|
* System.Storage.Find interop now support "Backwards" flag to iterate in the
|

|
|
|
|
Behaviour changes:

|
|
interop package (#2941)
|
|
* a number of deprecated RPC-related Prometheus counters are permanently
|
|
removed (#2941)
|
|
* NEP-2 account label will be asked on account import via CLI (#2889)
|
|
* hashes and states of native contracts are now accessible via native
|
|
ContractManagement API (#2991)
|
|
* `serv_node_version` gauge Prometheus metric is marked as deprecated and
|
|
replaced by `neogo_version` and `server_id` (#3009)
|
|
* strict contract script check is back with Basilisk hardfork, it was
|
|
previously removed in 0.101.3 for 3.5 protocol compatibility (#3056)
|
|
* JSON number deserialization (via StdLib.jsonDeserialize) changes with
|
|
Basilisk hardfork allowing for more precision and handling more corner
|
|
cases (#3080)
|
|
* notification type errors are treated as fatal after Basilisk hardfork,
|
|
before it they're just logged (#3086)
|
|
* NULL and non-UTF8 items are not allowed for String event types (#3086)
|
|
* `Conflicts` and `NotValidBefore` transaction attributes are no longer NeoGo
|
|
extensions, they can be used on regular networks (#2962)
|
|
|
|
Improvements:
|
|
* documentation and example improvements (#2945, #2972, #2979, #3020, #3084,
|
|
#3099, #3114, #3116, #3119, #3121)

|
|
* special exported error returned in case of WSClient disconnection (#3000)
|

|
|
* economic adjustment for ranking of transactions with `Conflicts` attribute (#3031)
|
|
* `google.golang.org/grpc` dependency upgrade fixing high severity security
|
|
vulnerability (#3055, gRPC is only used to communicate with NeoFS nodes in
|
|
the oracle service)
|
|

|
|
(not a part of node) (#3107)
|
|
* unwrap.Nothing function for RPC clients (#3117)
|
|

|
|
* invalid data source for `mempool_unsorted_tx` Prometheus metric (#2969)
|
|
* dBFT library upgrade fixing the ability of a single node to speed up the

|
|
|
|
## 0.101.4 "Yarborough" (01 Aug 2023)
|
|
|
|
Another one 3.5.0-compatible version that is aimed to fix T5 testnet state
|
|
difference that has happened at block 2336911 which leads to inability to process
|
|
new blocks since 2418703. The issue is fixed by allowing JSON numbers
|
|
unmarshalling from scientific notation to Integer stackitem. Maximum parsing
|
|
precision for such numbers is currently restricted by 53 bits. This is a
|
|
temporary C#-compatible solution that is likely to change in the future versions
|
|
when an appropriate C# node bug is fixed (neo-project/neo#2879).
|
|
|
|
A set of minor bug fixes is included as well to flush some of the long-awaited
|
|
changes that were blocked by the 0.102.0 release delay (caused by v3.6.0 C# node
|
|
release delay). In particular, invalid headers returned by an RPC server for
|
|
error responses, invalid format of incremental dumps created by CLI and deadlock
|
|
on unhealthy RPC server shutdown. Long-awaited `--config-file` CLI option to
|
|
start the node providing a single configuration file is added.
|
|
|
|
T5 testnet chain requires a complete resynchronization for this version. Mainnet
|
|
chain resynchronization is recommended, but not required.
|
|
|
|
New features:
|
|
* `--config-file` CLI option allowing to start the node with a single configuration file (#3014)
|
|
|
|
Improvements:
|
|
* blockchain Notary and Oracle services documentation improvement (#2972)
|
|
* BoltDB (`go.etcd.io/bbolt`) dependency upgrade that fixes a number of Windows-related issues (#3034)
|
|
|
|
Bugs fixed:
|
|
* panic on node start with invalid configuration (#2968)
|
|
* deadlock on unhealthy RPC server shutdown (#2966)
|
|
* improper WSClient notification channels managing after disconnection (#2980)
|
|
* missing Prometheus metric initialisation on node start (#2992)
|
|
* invalid initialisation of native contracts cache (#2994)
|
|
* incorrect way of incremental DB dumps creation (#3047)
|
|
* Notary contract is allowed to be a sender of main Notary request transaction (#3065)
|
|
* discrepancy in signer's witness scope parsing on the RPC server side (#3060)
|
|
* Invoker calling API isn't allowed to accept nil parameter (#3067)
|
|
* contract RPC Client unwrapper helper can't handle missing contract case (#3072)
|
|
* JSON numbers can't be unmarshalled to stackitem from scientific notation (#3073)
|
|
* invalid content-type header returned by RPC server on error responses (#3075)
|
|
|
|
## 0.101.3 "Yuckiness" (08 Jul 2023)
|
|
|
|
Yet another 3.5.0-compatible emergency version that removes scrupulous
|
|
instructions check of smart contract's script on contract deployment or update.
|
|
Presence of this check leads to the known T5 testnet state incompatibility
|
|
(since 1670095) which causes inability to process new blocks (since 2272533).
|
|
It should be noted that the corresponding check was accidentally removed from
|
|
the reference C# node implementation way back in neo-project/neo#2266 and added
|
|
again in neo-project/neo#2849 which is planned to be a part of the upcoming
|
|
3.6.0 C# node release. Thus, changes made in the presented 0.101.3 release will
|
|
be reverted afterwards and strict contract script check will be present in the
|
|
next 3.6.0-compatible version of NeoGo node.
|
|
|
|
T5 testnet chain requires a complete resynchronization for this version. Mainnet
|
|
chain resynchronization is recommended.
|
|
|
|
Bugs fixed:
|
|
|
|
* extra strict contract script check on contract deployment or update is
|
|
removed (#3052)
|
|
|
|
## 0.101.2 "Excavation" (29 Jun 2023)
|
|
|
|
One more (and unexpected one!) 3.5.0-compatible version that fixes a VM bug
|
|
leading to mainnet state incompatibility (since 3672783) which in turn leads
|
|
to inability to process new blocks (since 3682290).
|
|
|
|
Mainnet chain needs to be resynchronized for this version.
|
|
|
|
Improvements:
|
|
* documentation updates (#3029, #2990, #2981)
|
|
|
|
Bugs fixed:
|
|
* incorrect handling of empty Any-type parameter for RPC invocations (#2959)
|
|
* incorrect state rollbacks in case of exception during cross-contract call
|
|
when the call is made from non-TRYing context (#3046)
|
|
|
|
## 0.101.1 "Shallowness" (17 Mar 2023)
|
|
|
|
Another 3.5.0-compatible version that delivers important bug fixes and
|
|
provides a new API to be used by NeoFS. An upgrade is recommended, the DB
|
|
doesn't need to be resynchronized.
|
|
|
|
New features:
|
|
* internal RPC client for deeply integrated applications like NeoFS (#2916)
|
|
|
|
Improvements:
|
|
* documentation updates (#2879, #2880, #2893, #2917, #2920, #2936)
|
|
* code style, spelling and updated linter fixes (#2884, #2922, #2933)
|
|
* NEP-2 import password can be provided via config file now (#2887)
|
|
* custom stack item deserialization limit is available via public APIs now (#2904)
|
|
* RPC client endpoint can be retrieved via public API (#2915)
|
|
* dependency updates (#2919, #2929)
|
|
* WSClient now copies filter parameters to Subscribe* and Receive* methods
|
|
improving code safety (#2937)
|
|
|
|
Bugs fixed:
|
|
* name parameter ignored for wallet import command (#2887)
|
|
* incorrect RPC binding code generated for Any return type (#2918)
|
|
* memory leak on active peer disconnection (#2924)
|
|
* consensus process deadlock (#2930)
|
|
* dBFT deadlock in "committed at previous view" scenario (#2935)
|
|
* panic in RPC waiter code (#2938)
|
|
|
|
## 0.101.0 "Shortness" (13 Jan 2023)
|
|
|
|
This release delivers an important fix for block execution application logs
|
|
and requires a resynchronization, therefore it's 0.101.0 (even though it's
|
|
also 3.5.0-compatible). It fixes some other minor problems as well (the other
|
|
most notable change probably is in the compiler), so we recommend upgrading.
|
|
|
|
Improvements:
|
|
* updated golang.org/x/* dependencies (#2854)
|
|
* CLI help and required flags handling fixes (#2852)
|
|
* transfer data storage optimization (#2865)
|
|
* network's magic number is stored (and checked against the config on
|
|
startup) in the DB now, reducing potential for node operator errors (#2867)
|
|
|
|
Bugs fixed:
|
|
* in rare cases nodes could request an invalid number of blocks from peers
|
|
leading to disconnect (#2846)
|
|
* outdated documentation fixes (#2860, #2876)
|
|
* application logs for blocks that contained GAS spends for transaction fees
|
|
contained (and returned from getapplicationlog RPC) incorrect (off by one)
|
|
values for amount in Transfer events; transaction application logs were not
|
|
affected by this, but data returned to RPC event subscribers could
|
|
potentially be (#2865)
|
|
* findstates RPC returned an error instead of an empty data set for valid
|
|
contracts that have no data (unlike C# node, #2866)
|
|
* miscompiled shadowed range loop variable definition (#2871)
|
|
* missing (compared to C# node) explicit (even though null) 'exception' field
|
|
in the getapplicationlog RPC output from server (#2872)
|
|
|
|
## 0.100.1 "Chaptalization" (28 Dec 2022)
|
|
|
|
This is a tiny update that 99.99% of users can easily skip. The reason for
|
|
this release is the need to fix compatibility with the NeoFS mainnet
|
|
sidechain and have some stable version to be used there. In any other case it
|
|
can be ignored, but if you still decide to upgrade you don't need to
|
|
resynchronize.
|
|
|
|
Behaviour changes:
|
|
* Aspidochelone fork is made to include ContractManagement native contract
|
|
deploy/update methods call flags change, initially it was an unconditional
|
|
part of 0.99.0 NeoGo release (or 3.2.0 C# version), but this behavior is
|
|
incompatible with the NeoFS mainnet sidechain; the change to the fork logic
|
|
does not affect any other public networks (mainnet/testnet) and any new
|
|
networks that have Aspidochelone enabled since block 0 (#2848)
|
|
|
|
Improvements:
|
|
* more robust NEP-11 divisibility check in the RPC server code (#2841)
|
|
* microoptimization for some debug log messages (#2842)
|
|
* additional fuzz tests for integer serialization and script parsing code (#2851)
|
|
|
|
## 0.100.0 "Centuplication" (08 Dec 2022)
|
|
|
|
A 3.5.0-compatible version of NeoGo with all the appropriate protocol updates
|
|
and a number of other changes. The most notable ones are configuration
|
|
updates. New features and some long-standing inconsistencies required for some
|
|
changes and this release brings them with it. Old configurations are still
|
|
supported and will work the same way (except for one minor exception in
|
|
VerifyBlocks that is only supposed to be used for tests/development), but we'd
|
|
like to highlight that all of the old settings will be removed in ~6 months,
|
|
so please review these updates and update your configurations. For public
|
|
networks the best way to go is to take the new versions from the "config"
|
|
directory and then adjust for particular scenario if needed.
|
|
|
|
This release requires a complete resynchronization due to native contract
|
|
changes, so please schedule your updates appropriately.
|
|
|
|
New features:
|
|
* System.Runtime.LoadScript syscall (and appropriate smart contract interops)
|
|
allowing to load/run dynamic code (#2719)
|
|
* PUSHT/PUSHF VM instructions allowing for simpler/cheaper booleans (#2770)
|
|
* ContractManagement native contract was extended with ID->hash mappings and
|
|
`getContractById` and `getContractHashes` methods (#2702, #2837)
|
|
* LogLevel application configuration option that can be changed on SIGHUP
|
|
(#2831)
|
|
* additional type data generated by the compiler that then can be used by the
|
|
RPC bindings (SDK/contract wrapper) generator, this allows for complex
|
|
types (structures/arrays/maps) to be easily represented/handled in
|
|
contract-specific RPC code (#2828)
|
|
* multiaddress listeners for all services and P2P, this changes the old
|
|
Address/Port (and AnnouncedPort for P2P) configuration scheme to more
|
|
generic Addresses list, the old configuration is still supported, but is
|
|
deprecated and will be removed in future node versions (#2827, #2839)
|
|
|
|
Behaviour changes:
|
|
* Aspidochelone fork block for NeoFS sidechain mainnet configuration is
|
|
rescheduled again (#2823, #2830)
|
|
* Blockchain's GetHeaderHash() method now accepts uint32 for parameter
|
|
(#2814)
|
|
* pre-0.97.3 and pre-0.99.0 deprecated compatibility fields and logic were
|
|
dropped from the result.Version (`getversion` RPC result) structure (#2786)
|
|
* SecondsPerBlock protocol configuration variable was replaced with
|
|
TimePerBlock allowing for sub-second precision, SecondsPerBlock is still
|
|
supported, but will eventually be removed (#2829)
|
|
* AttemptConnPeers, BroadcastFactor, DialTimeout, ExtensiblePoolSize,
|
|
MaxPeers, MinPeers, PingInterval, PingTimeout, ProtoTickInterval settings
|
|
were moved into the new P2P section, timing parameters now use Duration
|
|
type allowing for more human-friendly values in many cases, old parameters
|
|
are still supported, but will eventually be removed (#2827)
|
|
* consensus (dBFT) is configured as a separate service now that can be
|
|
enabled/disabled (and can work in "watch only" mode without a wallet), the
|
|
old direct "UnlockWallet" specification in "ApplicationConfiguration" is
|
|
still supported, but is deprecated and will be removed in future versions
|
|
(#2832)
|
|
* GarbageCollectionPeriod, KeepOnlyLatestState, RemoveUntraceableBlocks,
|
|
SaveStorageBatch and VerifyBlocks settings were moved from
|
|
ProtocolConfiguration to ApplicationConfiguration; old configurations are
|
|
still supported, except for VerifyBlocks which is replaced by
|
|
SkipBlockVerification with inverted meaning (and hence an inverted default)
|
|
for security reasons; this also affects NewBlockchain and neotest APIs
|
|
(#2833)
|
|
|
|
Improvements:
|
|
* more user-friendly error and help messages in some cases (#2824, #2834)
|
|
* faster node startup time and smaller memory footprint for networks with
|
|
lots (1-2M+) of blocks (#2814)
|
|
* minor documentation fixes (#2834, #2838)
|
|
|
|
Bugs fixed:
|
|
* transactions with system fee or more than MaxBlockSystemFee are no longer
|
|
accepted into the mempool, preventing a form a network-wide DoS (#2826)
|
|
* deprecated WSClient subscription methods not working correctly when filters
|
|
are being used (#2836)

## 0.99.7 "Hyalinization" (23 Nov 2022)
|
|
|
|
Bugs, terrestrial arthropods with at least six legs. Sometimes we don't notice
|
|
them, sometimes we ignore them, but they do exist and there are times when
|
|
they need to be dealt with in one way or another. Most of the bugs fixed in
|
|
this release have a little less legs than proper insects, they're far from
|
|
being as critical as the ones fixed in the previous release and yet we
|
|
consider them annoying enough to warrant this new version of NeoGo to be
|
|
published. We don't want to see our users fighting these pesky creatures in
|
|
the wild, better update and have a troublefree experience.
|
|
|
|
If you're not affected by #2815 (requests for verbose transaction data and
|
|
application logs failed for some specific mainnet transaction(s)) you may
|
|
leave the DB as is with this upgrade, if you want it to be solved then please
|
|
resynchronize.
|
|
|
|
Behaviour changes:
|
|
* "loadtx" VM CLI command now uses transaction system fee value as the
|
|
default GAS limit for the context, unless --gas is used (previously it
|
|
wasn't limited, #2816)
|
|
* SendRawTransaction RPC client method will now always return transaction
|
|
hash, even if error occured, this also affects Actor APIs and allows to
|
|
handle some specific errors (like transaction already present in the
|
|
mempool) in more appropriate way (#2817)
|
|
* Actor and NotaryActor Wait() wrapper methods now handle "already exists"
|
|
and "already on chain" errors as non-errors, waiting (if needed) and
|
|
returning proper results (#2817)
|
|
|
|
Improvements:
|
|
* reworked network discoverer/connection manager that has a better picture of
|
|
the network (especially if it's a small one), doesn't try to make additional
|
|
connections (even when having less than MinPeers of them) when there are no
|
|
more real addresses to connect to, establishes stable connections faster in
|
|
containerized environments and does more connection attempts when MinPeers
|
|
setting is not satisfied, but there are potential candidates (#2811)
|
|
* VM invocation stack handling microoptimization (#2812)
|
|
* load* VM CLI commands now accept --gas parameter to set the amount of GAS
|
|
to be used in this context (#2816)
|
|
* better logging during state reset process (#2813)
|
|
* subscription-based transaction waiter now handles already accepted
|
|
transactions faster (~immediately vs waiting for block timeout previously,
|
|
#2817)
|
|
* WSClient can return more specific error on websocket handshake failure if
|
|
it's provided by server (#2821)
|
|
* new MaxWebSocketClients configuration option for the RPC server to control
|
|
the number of allowed websocket clients, missing or 0 value make the server
|
|
use the default of 64 which is compatible with the previous behavior (you
|
|
can use old configurations if you don't care about this option, #2821)
|
|
|
|
Bugs fixed:
|
|
* occasional "loadgo" VM CLI test failures because of timeout (#2810)
|
|
* websocket waiter test instability (#2809)
|
|
* websocket event unsubscriptions could lead to node deadlock in rare
|
|
circumstances (#2809)
|
|
* exception handler could use improper evaluation stack in some cases (#2812)
|
|
* pointer stack items were not handled correctly in "protected" serialization
|
|
mode leading to inability to deserialize these items back (#2816)
|
|
* state reset functionality not working for big chains like mainnet (#2813)
|
|
|
|
## 0.99.6 "Funambulation" (16 Nov 2022)
|
|
|
|
An emergency release fixing mainnet incompatibility at block 2504320 leading
|
|
to inability to process block 2504813. A couple of other less severe bugs got
|
|
fixed as well. Unfortunately, this release requires complete resynchronization
|
|
for mainnet, other networks can use old DBs.
|
|
|
|
Improvements:
|
|
* only transactions requested by the consensus process are forwarded to it
|
|
now slightly improving performance in some networked scenarios (#2788)
|
|
* a complete set of simple array unwrappers in the unwrap library (#2792)
|
|
* RPC binding generator can handle simple arrays now with configuration file
|
|
provided (#2792)
|
|
* more user-friendly error messages in some cases (#2797, #2802, #2804)
|
|
|
|
Bugs fixed:
|
|
* DB was not properly closed after state reset (#2791)
|
|
* VM stack handling problem leading to lost items after return from call to
|
|
another contract (#2800)
|
|
* "istack" command panic in the VM CLI (#2800)
|
|
* failure to decode incorrect contract from ContractManagement state leading
|
|
to failure to start the node, it'll be ignored now similar to how C# node
|
|
treats this (#2802)
|
|
* subscription to execution events failed if no "state" filter was used along
|
|
with "container" (#2804)
|
|
* Actor using WSClient could deadlock in the transaction waiter during
|
|
unsubscription (#2804)
|
|
|
|
## 0.99.5 "Underestimation" (11 Nov 2022)
|
|
|
|
It wasn't long since the previous release until a juicy set of features and
|
|
optimisations came on board. So we've decided to change our release plan and
|
|
supply one more 3.4.0 compatible version. It comes up with a massive suite
|
|
of network P2P and broadcast improvements. We've carefully investigated message
|
|
sending timeouts on benchmarks, reworked the broadcast logic and significantly
|
|
reduced delays in message sending and the amount of useless traffic between our
|
|
nodes. For smart-contract developers and RPC client users several new features
|
|
were added. These are automatic RPC bindings generator, poll-based and
|
|
websocket-based transactions awaiting and an extended websocket client
|
|
subscriptions interface. For better debugging experience we've improved state
|
|
related functionality of VM CLI and added an ability to reset chain state to a
|
|
particular height.
|
|
|
|
An important dBFT initialization bug that caused timestamp-related errors on
|
|
block addition was fixed. Also, those who use NeoGo node with
|
|
EnableCORSWorkaround setting may want to update the node to be able to handle
|
|
web-socket requests with Origin set in the header. The users of websocket RPC
|
|
client subscription mechanism are welcomed to move from deprecated subscriptions
|
|
API to the extended one. Finally, we are kindly asking our users to have a look
|
|
at our roadmap file where deprecated code removal schedule is attached.
|
|
|
|
This version is fully compatible with C# node 3.4.0 and does not require
|
|
resynchronization on upgrade. This time for sure, the next release is planned
|
|
to be compatible with 3.5.0.
|
|
|
|
New features:
|
|
* logarithmic gossip fan-out, new `BroadcastFactor` application setting and
|
|
adaptive peer requests are added to optimise broadcasting process (#608,
|
|
#2678, #2743)
|
|
* Prometheus histograms with handling time are added for P2P commands (#2750)
|
|
and RPC calls (#2784)
|
|
* transaction awaiting is added to RPC clients (#2740, #2749)
|
|
* RPC bindings generator (#2705) is added for both safe (#2766) and
|
|
state-changing (#2769, #2778) methods with initial iterator support (#2783)
|
|
* the ability to reset chain state to a particular height is added (#2576,
|
|
#2773)
|
|
|
|
Behaviour changes:
|
|
* Aspidochelone fork block for NeoFS sidechain mainnet configuration is
|
|
rescheduled (#2754, #2776)
|
|
* RPC server will now handle any Origin in websocket connection when
|
|
EnableCORSWorkaround setting is on (#2772, #2724)
|
|
* WS RPC client subscriptions API is extended to accept custom subscriber
|
|
channels, old subscriptions API is marked as deprecated (#2756, #2764)
|
|
|
|
Improvements:
|
|
* network code refactoring (#2742)
|
|
* network packets sending is now limited in time (#2738)
|
|
* broadcast messages will be sent concurrently to each peer (#2741)
|
|
* ping messages are broadcast using the common broadcast logic (#2742)
|
|
* transactions requested by dBFT will be accepted on demand only (#2746, #2748,
|
|
nspcc-dev/dbft#63)
|
|
* VM CLI's state-based functionality improvements (extended signers and
|
|
arguments parsing, enabled logging) and additional commands (`loadtx`,
|
|
`loaddeployed`, `jump`) (#2729, #2606, #2740)
|
|
* incoming P2P transactions are now processed concurrently and buffer for
|
|
inventory hashes is reusable (#2755)
|
|
* `GetData` and `GetBlocksByIndex` replies are now batched on a TCP-level
|
|
(#2757)
|
|
* optimisation of incoming P2P transactions and blocks filtering are introduced
|
|
(#2758, #2759)
|
|
* batch size of broadcast transactions hashes is adjusted (#2760)
|
|
* peer reconnections logic is improved, `GetAddr` messages are sent more
|
|
often (#2761, #2745)
|
|
* documentation for wallet configuration file is clarified (#2763)
|
|
* Koblitz curve implementation of btcd/btcec was replaced with decred/secp256k1
|
|
due to GitHub security warning (#2781)
|
|
* `NOT` opcode for Bool emission is now used to reduce resulting script
|
|
cost (#2762)
|
|
|
|
Bugs fixed:
|
|
* failing tests cleanup on Windows (#2736)
|
|
* race in CLI test (#2765)
|
|
* invalid conversion of PublicKey smart contract parameter to emitable (#2739)
|
|
* initialize dBFT's context with previous block's timestamp on view 0 (#2753,
|
|
#2752, nspcc-dev/dbft#64)
|
|
|
|
## 0.99.4 "Transliteration" (07 Oct 2022)
|
|
|
|
A small update mostly interesting for people building/testing smart contracts
|
|
with NeoGo. It contains long-awaited VM CLI update that allows to use
|
|
blockchain state and complete set of interops, additional helper functions for
|
|
smart contracts and notification checking code (for upcoming 3.5.0 protocol
|
|
changes). Node operators using EnableCORSWorkaround (that is still not
|
|
recommended, but available) also may want to update to be able to handle
|
|
pre-flight CORS requests.
|
|
|
|
This version is compatible with C# node 3.4.0 and does not require
|
|
resynchronization on upgrade. The next release is planned to be compatible
|
|
with 3.5.0.
|
|
|
|
New features:
|
|
* address conversion helpers for smart contracts (#2698)
|
|
* interop helper to call specific version of a contract (#2695)
|
|
* notifications are now checked for manifest compliance, a warning is logged
|
|
in case on detected inconsistencies (#2710)
|
|
* VM CLI can now use blockchain state DB (including historic states) to run
|
|
code with a complete set of interops and contracts available; additional
|
|
commands were added to it to inspect storage and generated events (#2723)
|
|
|
|
Behavior changes:
|
|
* type assertion with two return values in Go contracts can't be compiled now
|
|
(it never worked properly, #2718)
|
|
* RPC server will now handle pre-flight CORS requests (via OPTIONS methods)
|
|
when EnableCORSWorkaround setting is on (#2724)
|
|
* all transaction-generating CLI commands were unified to accept
|
|
gas/sysgas/out/force parameters, ask for confirmation and be able to save
|
|
transaction into a file; this affects wallet claim and candidate-related
|
|
commands mostly (#2731)
|
|
|
|
Improvements:
|
|
* smartcontract.Builder API was extended with Len method (#2691)
|
|
* NNS example contract adjustments for better DNS compatibility (#2679)
|
|
* documentation updates (#2708, #2722, #2726, #2728)
|
|
* compiler now emits code to explicitly cast runtime.Notify() parameters to
|
|
appropriate types (#2720)
|
|
* CLI tests repackaging (#2725)
|
|
* NeoFS sidechain configurations for mainnet and testnet (#2730)
|
|
|
|
Bugs fixed:
|
|
* panic on node shutdown (#2689)
|
|
* panic on inlined append() compilation (#2716)
|
|
|
|
## 0.99.3 "Simplification" (09 Sep 2022)
|
|
|
|
Version 0.99.3 brings with it most of the planned refactoring changes to the
|
|
RPC client. dApp backend code can be greatly simplified in many cases by
|
|
using new APIs (old ones are still available for transition period of about
|
|
one-two releases more). We also have some updates for CLI and compiler and a
|
|
number of bug fixes.
|
|
|
|
This version is compatible with C# node 3.4.0 and does not require
|
|
resynchronization on upgrade. The next release is planned to be compatible
|
|
with 3.5.0 (if it's to be released around currently planned dates).
|
|
|
|
New features:
|
|
* native contract RPC wrappers (#2643, #2646, #2650, #2666, #2665)
|
|
* NEP-11 RPC wrappers (#2651)
|
|
* invoker interface extension with session-based iterators support (#2650)
|
|
* notary Actor greatly simplifying creation of notary-assisted transactions
|
|
via RPC client (#2665)
|
|
* historic smart contract calls can now be made via CLI (#2683)
|
|
|
|
Behavior changes:
|
|
* calculatenetworkfee RPC can handle paid attributes (NeoGo extensions) and
|
|
invalid contract signatures now, it won't return an error for them (#2658)
|
|
* graceful node shutdown on SIGTERM (#2660)
|
|
* wallet balance commands now require at least 0.99.1 NeoGo version (or
|
|
compatible C# node) used by the RPC server (#2667)
|
|
|
|
Improvements:
|
|
* build system corrections (#2641, #2684)
|
|
* additional types in `unwrap` (#2650, #2651)
|
|
* session iterator consistency check in `unwrap` (#2650)
|
|
* multitransfers in NEP-17 RPC wrapper (#2653)
|
|
* extended transaction validity time in CLI wallet commands (#2653)
|
|
* reference counter optimization in VM (#2659)
|
|
* RPC Actor API can have default (used for all transactions) attributes and
|
|
callbacks now (#2665)
|
|
* neptoken RPC package can now provide wallet.Token data (#2667)
|
|
* NEP-11 balance commands can now work without direct token hash
|
|
specification or previous token import (#2667)
|
|
* support for offline signing in CLI (#2668)
|
|
* compiler can optimize out unused global variables now (#2624)
|
|
* private keys are now cleaned up from memory when they're no longer needed,
|
|
additional Account APIs added to reduce direct interactions with private
|
|
keys (#2672)
|
|
* updated linter settings, some code cleanup (#2674)
|
|
* more documentation and examples for new RPC APIs (#2681)
|
|
* refactored state-changing methods of NEP-11/NEP-17 RPC wrappers into a
|
|
separate structure to simplify reusing them in higher-level code (#2681)
|
|
* simplified rpcclient historic API (#2686)
|
|
|
|
Bugs fixed:
|
|
* compiler panic on empty package list (#2645)
|
|
* compiler not allowed to use unnamed parameters in exported methods (#2648)
|
|
* compiler allowed to export multireturn functions (#2648)
|
|
* compiler panic on nil method receiver in the compiled code (#2649)
|
|
* compiler panic on variable initialization from multireturn call (#2644)
|
|
* potential lockups or panics on node shutdown (#2652)
|
|
* contract manifest not checked for correctness in bindings generation CLI
|
|
command (#2656)
|
|
* SignTx wallet Account API could lead to inconsistent result in some cases
|
|
(#2665)
|
|
* wallet Account API allowed to sign with locked accounts (#2665)
|
|
* potential panic in keys.WIFDecode on some inputs (#2672)
|
|
|
|
## 0.99.2 "Recalibration" (12 Aug 2022)
|
|
|
|
This is a 3.4.0-compatible (tested for mainnet and testnet) update to NeoGo
|
|
that implements all of the required protocol changes, adds a lot of new RPC
|
|
client interfaces and provides additional service management functions. This
|
|
is also the first version to support the recently released Go 1.19. Support
|
|
for Go 1.16 is removed at the same time, so you need Go 1.17+ to build NeoGo
|
|
now.
|
|
|
|
With this version you can turn on/off, restart or reconfigure internal node
|
|
services like RPC or Oracle without full node shutdown/startup. Node operators
|
|
can send an appropriate Unix signal and that'll do the job. At the same time
|
|
node operators must resynchronize their nodes when updating to 0.99.2 due to
|
|
native contract state change.
|
|
|
|
A number of RPC client's methods are now deprecated (but still available to
|
|
simplify transition), please explore new APIs, try them and leave feedback in
|
|
#2597 if any. We expect new APIs to better fit the needs of various backend
|
|
RPC client use cases while allowing to remove some repetitive code from
|
|
applications at the same time. This release only contains generic NEP-17 call
|
|
wrapper, so it doesn't cover all of the things currently provided by the
|
|
old client API, but this will be fixed in future releases.
|
|
|
|
New features:
|
|
* signal-based configuration and service reloads (#2612)
|
|
* new APIs in smartcontract package to convert Go types into NEP-14
|
|
parameters (#2621, #2632)
|
|
* invoker package to deal with invocations via RPC in various contexts
|
|
(mostly useful for read-only and/or historic calls when used directly,
|
|
#2621)
|
|
* `hasMethod` method in the ContractManagement native contract (#2598, #2619,
|
|
#2640)
|
|
* actor package that helps in creating and sending transactions to the
|
|
network via RPC using the same set of signers (can be used directly, but
|
|
mostly intended to be used by higher-order contract wrappers, #2632, #2637)
|
|
* unwrap package in the RPC client that checks for execution results and
|
|
converts returned stack items to expected Go types (can be used directly,
|
|
but more useful when being used by upper-layer contract wrappers, #2638)
|
|
* nep17 RPC client package for simple remote access to NEP-17 contract
|
|
methods via RPC, both safe and state-changing (#2642)
|
|
|
|
Behavior changes:
|
|
* smartcontract.Params type and (*Parameter).TryParse APIs were removed
|
|
completely as unused and not useful (#2621)
|
|
* compiler now rejects unnamed parameter for exported methods (but they
|
|
didn't work properly anyway, #2601)
|
|
* restored deploy-time out of bounds script checks (#2538, #2619)
|
|
* dynamic scripts (like entry scripts) no longer can emit notifications
|
|
(#2613)
|
|
* db dump and db restore CLI commands now reject `--debug` option (it was
|
|
ignored previously, #2625)
|
|
|
|
Improvements:
|
|
* manifest correctness check during compilation (#2601)
|
|
* more robust CalledByEntry scope check (#2613)
|
|
* a check for excessive arguments in CLI (#2625)
|
|
* better help messages for CLI commands (#2625)
|
|
* Go 1.19 support (#2634)
|
|
* saved transactions created via CLI (`--out`) now use the maximum possible
|
|
ValidUntilBlock values (#2632)
|
|
* RPC server now returns more data about NeoGo-specific protocol extensions
|
|
in `getversion` reply (#2632)
|
|
|
|
Bugs fixed:
|
|
* NEP-6 wallet version was wrong wrt the standard and C# implementation
|
|
(#2633)
|
|
* smart contract invocations from the CLI didn't compensate for interactive
|
|
prompt wait time which could lead to transaction expiration before it was
|
|
sent (#2632)
|
|
* Oracle native contract's `finish` method reentrancy problem (#2639)
|
|
|
|
## 0.99.1 "Parametrization" (28 Jul 2022)
|
|
|
|
We're updating NeoGo to push out a number of significant updates as well as
|
|
make it compatible with 3.3.1 version of C# node. The most prominent changes
|
|
are RPC sessions for iterators returned from invoke* calls, initial bits of
|
|
RPC client refactoring and support for darwin-arm64 and linux-arm64
|
|
platforms. A number of internal changes are less visible from outside, but
|
|
are also important for future evolution of the code base.
|
|
|
|
Node operators must resynchronize their nodes to get fully compatible state
|
|
(which is confirmed to be compatible with 3.3.1 for current mainnet up to
|
|
block 1932677 and T5 testnet up to block 475938). RPC client users, please
|
|
review the changes carefully and update your code wrt refactorings made as
|
|
well as iterator session support.
|
|
|
|
Subsequent releases will also change RPC client and associated code, we want
|
|
to make it easier to use as well as extend its functionality (see #2597 for
|
|
details, comments and suggestions are welcome). 0.99.2 is expected to be
|
|
released somewhere in August with 3.4.0 C# node compatibility.
|
|
|
|
New features:
|
|
* `getcandidates` RPC method to get full list of registered candidates and
|
|
their voting status (#2587)
|
|
* wallet configuration file support to simplify using CLI non-interactively,
|
|
use `--wallet-config` option instead of `--wallet` if needed (#2559)
|
|
* session-based JSON-RPC iterator API for both server and client with
|
|
`traverseiterator` and `terminatesession` calls; notice that the default
|
|
server behavior (`SessionEnabled: false`) is compatible with NeoGo 0.99.0,
|
|
iterators are expanded the way they were previously, only when sessions are
|
|
enabled they're returned by the server to the client (#2555)
|
|
* `interop` package now provides helper methods for proper `Hash160`,

`getcandidates` method (#2587)
|
|

|
|
|
|
## 0.99.0 "Overextrapolation" (03 Jun 2022)
|
|
|
|
A big NeoGo upgrade that is made to be compatible with C# node version
|
|
3.3.0. All of the protocol changes are implemented there with the main one
|
|
being the Aspidochelone hardfork that will happen on mainnet
|
|
soon. Compatibility is confirmed for current T5 testnet and mainnet, but this
|
|
version requires a resynchronization so schedule your updates accordingly.
|
|
|
|
But it's not just about the protocol changes, this release introduces an
|
|
ability to perform historic invocations via RPC for nodes that store old MPT
|
|
data. Using `invokefunctionhistoric` you can perform some invocation with the
|
|
chain state at the given height, retreiving old balances, ownership data or
|
|
anything else you might be interested in.
|
|
|
|
Please also pay attention to configuration files used by your node, mainnet
|
|
ones must have Aspidochelone hardfork enabled at height 1730000 to be
|
|
compatible and T5 testnet enables it at height 210000. T5 testnet is different
|
|
from T4, it uses different magic number, different seed nodes and different
|
|
protocol configuration settings. 0.99.0 won't work for T4 testnet, please
|
|
use 0.98.5 for it.
|
|
|
|
New features:
|

## 0.98.5 "Neutralization" (13 May 2022)
|
|
|
|
An urgent update to fix the same security issue that was fixed in 3.1.0.1 C#
|
|
node release. Please upgrade as soon as possible, resynchronization is not
|
|
needed for mainnet.
|
|
|
|
Bugs fixed:
|
|
* GAS emission now happens after NEO transfer is finished (#2488)
|
|
|
|
## 0.98.4 "Mesmerization" (11 May 2022)
|
|
|
|
An urgent release to fix incompatibility with mainnet at block 1528989. The
|
|
actual pair of problems leading to inability to process this block occurred
|
|
earilier than that, so to fix this you need to resynchronize your node. Fixed
|
|
node is confirmed to have identical state as 3.1.0 C# node up to block
|
|
1529810.
|
|
|
|
Bugs fixed:
|
|
* StdLib itoa() implementation emitted uppercase letters instead of lowercase
|
|
(#2478)
|
|
* StdLib jsonDeserialize() implementation couldn't handle properly integers
|
|
larger than 64-bit signed (#2478)
|
|
|
|
## 0.98.3 "Liquidation" (07 May 2022)
|
|
|
|
This is a hotfix release to fix t4 testnet incompatibility at block
|
|
1589202. The actual problem was found and fixed during 0.99.0 development
|
|
cycle, but 0.99.0 is expected to be incompatible with t4 testnet. This release
|
|
allows to continue working with it as well as mainnet (and contains some other
|
|
fixes for known problems). It does not require resynchronizing a node.
|
|
|
|
Improvements:
|
|
* double call to `WSClient.Close()` method won't cause a panic (#2420)
|
|
|
|
Bugs fixed:
|
|
* Rules scope considered as invalid in binary representation (#2452)
|
|
* incorrect compressed P2P message could lead to panic (#2409)
|
|
* notary-assisted transaction could be in inconsistent state on the Notary
|
|
node (#2424)
|
|
* WSClient panics if request is made after connection breakage (#2450)
|
|
* Rules scope JSON representation wasn't compatible with C# implementation
|
|
(#2466)
|
|
* JSONized Rules scope could only contain 15 conditions instead of 16 (#2466)
|
|
|
|
## 0.98.2 "Karstification" (21 Mar 2022)
|
|
|
|
We've decided to release one more 3.1.0-compatible version bringing all of the
|
|
new features and bug fixes (along with complete support for Windows platform)
|
|
made before going into full 3.2.0 compatibility. It's important for us to give
|
|
you more stable and flexible environment for the ongoing hackathon. Contract
|
|
bindings generator might be very useful for anyone operating with already
|
|
deployed contracts written in other languages, while the node itself can now
|
|
be configured for lightweight operation, keeping only the data relevant for
|
|
the past MaxTraceableBlocks, no more and no less. Current public networks
|
|
don't benefit from it yet with their large MaxTraceableBlocks setting, but
|
|
they're growing every day and it's just a matter of time when this feature
|
|
will start making a difference. And sorry, but this release is again faster
|
|
than the previous one.
|
|
|
|
We recommend updating, but if your node is not public and you don't
|
|
specifically want to play with new things brought by it you might as well wait
|
|
for the next one. It requires resynchronization and 0.99.0 will do too because
|
|
of planned protocol changes.
|
|
|
|
New features:
|
|
* protocol extension allowing to change the number of validators in existing
|
|
network (#2334)
|
|
* MPT garbage collection mechanism allowing to store a set of latest MPTs,
|
|
RemoveUntraceableBlocks setting now activates it by default unless
|
|
KeepOnlyLatestState is used (#2354, #2360)
|
|
* NEP-11/NEP-17 transfer data garbage collection (#2363)
|
|
* Go bindings generator based on contract manifests (#2349, #2359)
|
|
|
|
Behavior changes:
|
|
* some RPC client functions for divisible NEP-11 changed signatures using
|
|
slice of bytes now instead of strings for IDs (#2351)
|
|
* heavily refactored storage and dao package interfaces (#2364, #2366)
|
|
* support for Go 1.18 added, 1.15 dropped (#2369)
|
|
|
|
Improvements:
|
|
* additional CLI tests (#2341)
|
|
* `defer` statement is now compiled more effectively (#2345)
|
|
* `defer` statement can be used in conditional branches now (#2348)

|
|
depending on machine and configuration (#2364)
|
|
* reworked VM CLI fixing Windows incompatibility and UTF-8 bugs (#2365)
|
|
* incompletely signed transaction JSONs now also contain hash (#2368)
|
|
* RPC clients can now safely be used from multiple threads (#2367)
|
|
* additional tests for node startup sequences (#2370)
|
|
* customizable notary service fee for Notary extension (#2378)
|
|
* signers passed into RPC methods can now contain rules (#2384)
|
|
* compiler tests now take less time (#2382)
|
|
* some fuzzing tests added (#2399)
|
|
|
|
Bugs fixed:
|
|
* test execution result wasn't checked for CLI invocations that saved
|
|
transaction into file (#2341)
|
|
* exception stack wasn't properly cleared during CALL processing in VM (#2348)
|
|
* incorrect contract used in RPC client's GetOraclePrice (#2378)
|
|
* oracle service could be tricked by redirects into going to local hosts when
|
|
this was disabled (#2383)
|
|
* `invoke*` RPC functions could be used to trigger OOM with specially crafted
|
|
scripts (#2386)
|
|
* some edge-cased integer conversions were not exactly matching the behavior
|
|
of C# node in VM (#2391)
|
|
* HASKEY instruction wasn't working for byte arrays (#2391)
|
|
* specially-crafterd JSONPath filters for oracle requests could trigger OOM
|
|
(#2372)
|
|
* ENDFINALLY opcode before ENDTRY could lead to VM panic (#2396)
|
|
* IsScriptCorrect function could panic on specially-crafted inputs (#2397)
|
|
|
|
## 0.98.1 "Immunization" (31 Jan 2022)
|
|
|
|
Bug fixes, interesting optimizations, divisible NEP-11 example and a big
|
|
compiler update --- everything you wanted to find in this NeoGo update. It
|
|
requires chain resynchronization, but this resynchronization will be faster
|
|
than ever.
|
|
|
|
One thing should also be noted, even though this release is 3.1.0-compatible,
|
|
it is known to have a different state for testnet after block 975644, but it's
|
|
not a NeoGo fault, it'll be fixed in the next C# node release. The root cause
|
|
is well-known and is not considered to be critical compatibility-wise.
|
|
|
|
New features:
|
|
* support for reading the wallet from stdin in CLI (where it's possible, #2304)

|
* helper script to compare node states via RPC (#2339)
|
|
|
|
Behavior changes:
|
|
* zero balance is explicitly printed now for token-specific NEP-17 balance
|
|
requests from CLI (#2315)
|
|
* pkg/interop (used by smart contracts) is a separate Go module now (#2292,
|
|
#2338)
|
|
* smart contracts must be proper Go packages now (#2292, #2326)
|
|
|
|
Improvements:
|
|
* optimized application log storage (#2305)
|
|
* additional APIs in `neotest` framework (#2298, #2299)
|
|

|
|
more optimized code (#2306)
|
|
* DB seek improvements increasing chain processing speed by ~27% (#2316, #2330)
|
|
* updated NeoFS dependencies (#2324)
|
|
* optimized emitting zero-length arrays in `emit` package used to construct
|
|
scripts (#2299)
|
|
* native contract tests refactored using generic contract testing framework (#2299)
|
|
* refactored internal Blockchainer interfaces, eliminating unnecessary
|
|
dependencies and standardizing internal service behavior (#2323)
|
|
* consensus process now always receives incoming transactions which might be
|
|
helpful for accepting conflicting (wrt local pool) transactions or when the
|
|
memory pool is full (#2323)
|
|
* eliminated queued block networked re-requests (#2329)
|
|
* better error reporting and parameter handling in FindStates RPC client
|
|
method (#2328)
|
|
* invoke* RPCs now also return notifications generated during execution (#2331)
|
|

|
|
* better transfer data storage scheme resulting in faster getnep* RPC
|
|
processing (#2330)
|
|
* dropped deprecated `loader` package from compiler dependencies moving to
|
|
updated x/tools interface (#2292)
|
|
|
|
Bugs fixed:
|
|
* incorrect handling of missing user response in CLI (#2308)
|
|
* improper primary node GAS distribution in notary-enabled networks (#2311)
|
|
* excessive trailing spaces in the VM CLI output (#2314)
|
|
* difference in JSON escaping wrt C# node leading to state difference for
|
|
testnet at block 864762 (#2321)
|
|
* potential panic during node shutdown in the middle of state jump (#2325)
|
|
* wrong parameters for `findstates` call in RPC client (#2328)
|
|
* improper call flags in Notary contract `withdraw` method (#2332)
|
|
* incorrect ownerOf signature for divisible NEP-11 contracts (#2333)
|
|
* missing safeness check for overloaded methods in the compiler (#2333)

We've implemented all of Neo 3.1.0 protocol changes in this release (and
|
|
features like NEP-11 transfer tracker), but as usual it's not the only thing
|
|
it contains. If you're developing contracts in Go you might be interested in
|
|
contract testing framework this release brings with it, which allows you to
|
|
write automated tests in Go. You can also build a node for Windows now and
|
|
most of functionality works there (but some known problems still exist, so
|
|
this port is considered to be experimental for now). As usual there were some
|
|
optimizations made in various components as well as bug fixes.
|
|
|
|
There are also some things removed in this release, that is BadgerDB and
|
|
RedisDB support, this will allow us to optimize better for LevelDB and BoltDB
|
|
in future. Notice also that this release requires full node resynchronization.

## 0.97.3 "Exception" (13 Oct 2021)
|
|
|
|
This updated version of NeoGo is made to be compatible with Neo 3.0.3 bringing
|
|
with it all corresponding protocol changes and bug fixes so that you can use
|
|
it on public testnet and mainnet. It also brings with it a complete
|
|
experimental P2P state exchange extension for private networks as well as
|
|
additional optimizations. This is the first version requiring at least Go 1.15
|
|
to compile, so make sure your Go is up to date if you're not using pre-built
|
|
binaries. Protocol updates and bug fixes made in this release require a
|
|
resynchronization on upgrade.
|
|
|
|
We also make a final call on Badger and Redis DB issue #2130, if there are no
|
|
active users of them, support for both will be removed in the next release.
|
|
|
|
New features:
|
|
* MaxConnsPerHost RPC client option (#2151)
|
|
* P2P state exchange extension (#2019)
|
|
* transaction-related CLI commands now show calculated fees before
|
|
sending transaction to RPC node and ask for confirmation (#2180)

|
in JSON format (used for manual signing by multiple parties, #2179)
|
|
* `getstate` and `findstates` RPC to retrieve historic state data (#2207)
|
|
|
|
Behavior changes:
|

|
|
* blocking native contracts is no longer possible in Policy contract (#2155)

* NEF files now have Source field that can be specified in contract's
|
|
metadata (#2191)

|
|
* out of bounds exceptions can be catched in contracts now for PICKITEM and
|
|
SETITEM VM instructions (#2209)
|

|
* reduced number of memory allocations in some places (#2136, #2141)
|
|
* VM optimizations (#2140, #2148)
|
|
* notary subsystem documentation (#2139)
|

|
|
metadata (#2206)
|
|
|
|
Bugs fixed:
|
|
* incorrect CustomGroups witness scope check (#2142)
|
|
* empty leaf values were ignored for MPT calculcations (#2143)

|
|
enough for ms-precision N3 timestamps (#2212)
|
|
* PICKITEM instruction could fail on attempt to get an item with long key
|
|
from map (#2209)
|
|
|
|
## 0.97.2 "Dissipation" (18 Aug 2021)
|
|
|
|
We're rolling out an update for NeoGo nodes that mostly concentrates on
|
|
performance. We've tweaked and tuned a lot of code while staying compatible
|
|
with N3 mainnet and testnet. At the same time we're gradually introducing
|
|
changes required for our P2P state exchange extension and this affected DB
|
|
format, so you'll need to resynchronize on update. This update is not
|
|
mandatory though, 0.97.1 is still perfectly valid for N3 networks.
|
|
|
|
Note also that we're discussing removal of Badger and Redis databases support
|
|
in future releases, so if you're interested in them take a look at #2130.
|
|
|
|
Behavior changes:
|
|
* address blocking in Policy contract now also blocks calls to contracts with
|
|
blocked addresses (#2132)
|
|
|
|
Improvements:
|
|
* numerous memory and CPU optimizations across whole codebase (#2108, #2112,
|
|
#2117, #2118, #2122, #2123, #2128, #2114, #2133)
|
|
* preliminary work for P2P state exchange extension (#2119)
|
|
* `util convert` command now also detects public keys and converts them to
|
|
script hash/address (#2125)
|
|
|
|
Bugs fixed:
|
|
* key decoding functions could accept some additional data even though only
|
|
key is expected to be present (#2125)
|
|
* conflicting dummy transactions could stay in the DB even with block removal
|
|
enabled (#2134)
|
|
|
|
## 0.97.1 "Gasification" (06 Aug 2021)
|
|
|
|
We're updating NeoGo to make it compatible with the latest protocol changes
|
|
made in 3.0.2 version of C# node. But that's not the only thing we do, this
|
|
release also fixes one important bug, improves node's performance and adds CLI
|
|
support to add group signatures to manifests.
|
|
|
|
It requires resynchronization on upgrade.
|
|
|
|
New features:
|
|
* `contract manifest add-group` command to add group signatures to contract
|
|
manifest (#2100)
|
|
|
|
Behavior changes:
|
|
* GAS contract no longer has Refuel method, it could be used as DOS
|
|
amplification tool for attacks on network and there is no way to securely
|
|
fix it (#2111)
|
|
|
|
Improvements:
|
|
* memory store optimizations leading to substantial single-node TPS
|
|
improvements (#2102)
|
|
* various micro-optimizations across the board both for CPU usage and memory
|
|
allocations (#2106, #2113)
|
|
* optimized transaction decoding (#2110)
|
|
|
|
Bugs fixed:
|
|
* ping messages created with wrong value used for node's height (#2115)
|
|
|
|
## 0.97.0 "Ventilation" (02 Aug 2021)
|
|
|
|
This is an official 3.0.0-compatible release that is ready to be used both for
|
|
mainnet and testnet. Technically, 0.96.0 and 0.96.1 are compatible too, but
|
|
they need an updated configuration to work on mainnet while this version has
|
|
it covered.
|
|
|
|
We keep improving our node and this release is not just a repackage of
|
|
something older, so DB format changes require a resynchronization if you're
|
|
upgrading from 0.96.X.
|
|
|
|
Behavior changes:
|
|
* updated configuration for mainnet (#2103)
|
|
|
|
Improvements:
|
|
* documentation for contract configuration file (#2097)
|
|
* significant change to NEP-17 tracking code, it shouldn't affect valid
|
|
NEP-17 tokens, but now we store a little less data in the DB and get more
|
|
from token contracts when needed (for `getnep17balances` RPC for
|
|
example); this change is required for our future state exchange protocol
|
|
extension (#2093)
|
|
* improved block processing speed on multicore systems (#2101)
|
|
* JSON deserialization now has the same limits as binary, but this doesn't
|
|
affect any valid code (#2105)
|
|
|
|
Bugs fixed:
|
|
* potential deadlocks in notary-enabled nodes (#2064)
|
|
* wallet files not truncated properly on key removal (#2099)
|
|
|
|
## 0.96.1 "Brecciation" (23 Jul 2021)
|
|
|
|
New CLI commands, updated dependencies and some bugs fixed --- you can find
|
|
all of this in the new NeoGo release. It's compatible with 0.96.0 (except for
|
|
multisignature contexts, but you're not likely to be using them) and
|
|
confirmed to have proper RC4 testnet state up to 15K blocks (but 0.96.0 is
|
|
fine wrt this too). At the same time we recommend to resynchronize the chain
|
|
if you're using LevelDB or BoltDB, both databases were updated.
|
|
|
|
New features:
|
|
* `query candidates`, `query committee` and `query height` CLI commands
|
|
(#2090)
|
|
* `GetStateHeight` RPC client call support (#2090)
|
|
|
|
Behavior changes:
|
|
* `wallet candidate getstate` command was renamed to `query voter`, now it
|
|
also prints the key voted for and handles addresses with 0 balance without
|
|
spitting errors (#2090)
|
|
|
|
Improvements:
|
|
* `query tx` now outputs signer address along with script hash (#2082)
|
|
* updated many of node's dependencies including BoltDB and LevelDB, there are
|
|
no radical changes there, mostly just some fixes improving stability (#2087)
|
|
* better error messages in some places (#2089, #2091)
|
|
|
|
Bugs fixed:
|
|
* `query tx` command wasn't providing correct results if used with C# RPC
|
|
node (#2082)
|
|
* watch-only node (with a key, but not elected to participating in consensus)
|
|
could panic on receiving a number of Commit messages (#2083)
|
|
* `getstateheight` RPC call produced result in different format from C# node
|
|
(#2090)
|
|
* JSON representation of multisignature signing context wasn't compatible
|
|
with C# implementation (#2092)
|
|
|
|
## 0.96.0 "Aspiration" (21 Jul 2021)
|
|
|
|
We're updating NeoGo to support RC4 changes, there are some incompatible ones
|
|
so this version can't be used with RC3 networks/chains (RC3 testnet is
|
|
still available, please use 0.95.4 for it). This release was checked for RC4
|
|
testnet compatibility and has the same state as C# for the first 5K blocks.
|
|
|
|
No significant protocol changes are expected now as we're moving to final N3
|
|
release, but we'll keep updating the node fixing bugs (if any), improving
|
|
performance and introducing NeoGo-specific features.
|
|
|
|
New features:
|
|
* "System.Runtime.GetNetwork" system call (#2043)
|
|
* ContentTypeNotSupported oracle return code and content type configuration
|
|
for Oracle service (#2042)
|
|
* block header have "Nonce" field again which is used for
|
|
"System.Runtime.GetRandom" system call (#2066)
|
|
* import from incremental chain dumps (#2061)
|
|
* configurable initial (from the genesis block) GAS supply (#2078)
|
|
* "query tx" CLI command to check for transaction status (#2070)
|
|
|
|
Behavior changes:
|
|
* verification GAS limits were increased (#2055)
|
|
* SQRT price reduced (#2071)
|
|
* binary deserialization is now limited to 2048 (MaxStackSize) items (#2071)
|
|
* notary deposit is stored now as serialized stack item (#2071)
|
|
* testnet and mainnet configuration updates (#2077, #2079, #2081)
|
|
|
|
Improvements:
|
|
* faster stack item binary and JSON serialization (#2053)
|
|
* faster Storage.Find operation (#2057)
|
|
* additional documentation for public network CNs (#2068)
|
|
* better code reuse for native contract's data serialization (#2071, see new
|
|
stackitem.Convertible interface)
|
|
* some types from state package renamed to remove "State" word (#2075)
|
|
* util.ArrayReverse helper moved to package of its own with additional
|
|
helpers (#2075)
|
|
|
|
Bugs fixed:
|
|
* nested structure cloning could lead to OOM (#2054, #2071)
|
|
* addresses were not accepted for witness accounts in RPC calls (#2072)
|
|
* POW instruction could take unknown amount of time to complete for big
|
|
parameters (#2060)
|
|
* oracle contract could accept invalid user data (#2071)
|
|
* EQUAL for deeply nested structures could never complete (#2071)
|
|
* arrays and structures were limited to 1024 items (#2071)
|
|
* oracle fallback transactions could try using outdated ValidUntilBlock value
|
|
(#2074)
|
|
* oracle node starting from genesis block tried to process all requests from
|
|
the chain instead of only working with current ones (#2074)
|
|
* some tests used non-unique/wrong temporary files and directories (#2076)
|
|
|
|
## 0.95.4 "Yatter" (09 Jul 2021)
|
|
|
|
Making a fully compliant Neo node is not easy, there are lots of minuscule
|
|
details that could be done in a little different way where both ways are
|
|
technically correct but at the same time just different which is enough to
|
|
create some interoperability problems. We've seen that with Legacy node
|
|
implementation where we were functionally complete with 0.74.0 release but
|
|
some fixes kept coming up to the most recent 0.78.3 version. It was a bit
|
|
easier with Legacy because we already had some years-long chains to test the
|
|
node against while N3 is a completely new territory.
|
|
|
|
So we'd like to thank all RC3 hackathon participants as well as all other
|
|
people playing with N3 RC3 network, your joint efforts gave enough material
|
|
to keep us busy fixing things for some time. The chain moving forward hit more
|
|
and more edge cases with every block and this is actually very helpful, we saw
|
|
a lot of things that could be improved in our node and we improved them.
|
|
|
|
Now we're releasing 0.95.4 with all of these fixes which is still
|
|
RC3-compatible and it's stateroot-compatible with C# implementation up to 281K
|
|
blocks. Please resynchronize to get identic testnet state. And most likely
|
|
that's the last RC3-compatible release as we're moving forward to the official
|
|
3.0.0 release of C# version NeoGo will be updated with appropriate changes
|
|
(some of which are not compatible with RC3).
|
|
|
|
New features:
|
|
* 'sysgas' parameter for invocation and transfer CLI commands to manually add
|
|
some system fee GAS (#2033)
|
|
|
|
Behavior changes:
|
|
* contract calls are now checked against specified permissions by the
|
|
compiler (#2025)
|
|
* stack items with nesting levels of 10 and more won't be serialized to JSON
|
|
for purposes like including them into RPC call reply (#2045)
|
|
|
|
Improvements:
|
|
* AddHeaders() with multiple headers added at the same time now works with
|
|
StateRootInHeader option (#2028)
|
|
* cached GAS per vote value leads to substantially improved block processing
|
|
speed (#2032)
|
|
* failed native NEP-17 transfers now still re-save the old value to the
|
|
storage making state dumps compatible with C# (#2034)
|
|
* refactored and renamed some stackitem package functions, added proper error
|
|
values in all cases (#2045)
|
|
* RPC calls (and application logs) can now return real serialization errors
|
|
if there are any (previously all errors were reported as "recursive
|
|
reference", #2045)
|
|
* better tests (#2039, #2050)
|
|
|
|
Bugs fixed:
|
|
* wrong onNEP11Payment name in contract configuration examples (#2023)
|
|
* missing permission sections in contract configuration examples (#2023)
|
|
* buffer stack item deserialization created byte string (#2026)
|
|
* Extra contract manifest field serialization was reworked to match C#
|
|
implementation more closely (#2021)
|
|
* wildcard permission in manifest allowed any methods, while it shouldn't
|
|
(#2030)
|
|
* group permission in manifest worked incorrectly for a set of groups (#2030)
|
|
* call flags were JSONized in incompatible way (#2041)
|
|
* MPT update left branch nodes with 1 child in some cases (#2034, #2047)
|
|
* JSON marshalling code for stack items detected item recursion in some cases
|
|
where no actual recursion was present (#2045)
|
|
* binary serialization code for stack items could overwrite old errors in
|
|
some cases (#2045)
|
|
* binary serialization code for stack items wasn't ensuring maximum size
|
|
limit during serialization which could lead to OOM (#2045)
|
|
* batched MPT update create excessive extension nodes for the last child of
|
|
branch node in some cases (#2047)
|
|
* in some cases "TCP accept error" was logged during node shutdown (#2050)
|
|
* contract updating code was updating caches before they should've been
|
|
updated (#2050)
|
|
* INVERT/ABS/NEGATE unary operations were not copying their arguments (#2052)
|
|
|
|
## 0.95.3 "Yuppification" (17 Jun 2021)
|
|
|
|
One more N3 RC3-compatible release that fixes testnet state difference at
|
|
block 151376. Please resynchronize to get proper testnet state.
|
|
|
|
Behavior changes:
|
|
* NEP2-related functions in `crypto/keys` package changed a bit to allow
|
|
Scrypt parameters overriding, standard parameters are available via
|
|
`NEP2ScryptParams` function (#2001)
|
|
|
|
Improvements:
|
|
* better unit test stability (#2011, #2001)
|
|
* updated neofs-api-go dependency (with support for TLS-enabled NeoFS node
|
|
connections, #2003)
|
|
* removed annoying token matching warning (#2018)
|
|
|
|
Bugs fixed:
|
|
* state mismatch resulting from different committee candidate sorting (#2017)
|
|
|
|
## 0.95.2 "Echolocation" (10 Jun 2021)
|
|
|
|
This is another N3 RC3-compatible release and it's better in its RC3
|
|
compatiblity than the previous one because we've fixed some state mismatches
|
|
wrt C# implementation that were found on testnet. It is confirmed to have the
|
|
same state up to 126K height (which is current), but to get proper state you
|
|
need to resynchronize your node from the genesis.
|
|
|
|
New features:
|
|
* RPC notification subsystem was extended to support notary pool events, so
|
|
clients can now react on request additions (#1984)
|
|
* compiler now checks notification event name length to fit into the limit
|
|
(#1989)
|
|
* compiler now also checks for runtime.Notify() calls from Verify method
|
|
(which won't work anyway, #1995)
|
|
|
|
Improvements:
|
|
* codegeneration improvements removing some unnecessary store/loads and type
|
|
conversions (#1881, #1879)
|
|
* additional MPT tests added ensuring compatibility with C# implementation
|
|
(#1993)
|
|
* additional consistency check added to prevent node running with native
|
|
contracts differing from the ones saved in DB (#2010)
|
|
|
|
Bugs fixed:
|
|
* `calculatenetworkfee` RPC result used format different from C# node (#1998)
|
|
* `CALLT` opcode was missing any price leading to wrong GAS calculations and
|
|
different state wrt C# node (#2004)
|
|
* '+' character was emitted directly by `jsonSerialize` method which is fine
|
|
wrt JSON itself, but differs from C# node behavior leading to node state
|
|
difference (#2006)
|
|
* NEO self-transfers were not checking the amount transferred (they didn't
|
|
change balance, but they succeeded) leading to state difference wrt C#
|
|
implementation (#2007)
|
|
|
|
## 0.95.1 "Shiftiness" (31 May 2021)
|
|
|
|
Bringing NeoGo up to date with N3 RC3 changes this release also improves
|
|
compiler and CLI a bit.
|
|
|
|
This release is mostly compatible with 0.95.0, but you need to resynchronize
|
|
your chains to have proper stateroot data and to make new methods available to
|
|
contracts. At the same time there won't be long-term support provided for it,
|
|
just as with all previous previews and RC.
|
|
|
|
New features:
|
|
* base58CheckEncode/base58CheckDecode methods in StdLib native contract
|
|
(#1977, #1979)
|
|
* getAccountState method in NeoToken native contract (#1978, #1986)
|
|
* custom contracts and groups can now be specified for witness scopes in
|
|
invocations from CLI (#1973)
|
|
|
|
Improvements:
|
|
* local variable handling was refactored in the compiler, removing some
|
|
duplicate code and improving robustness (#1921)
|
|
* CLI help now describes how "unvote" can be done (#1985)
|
|
|
|
Bugs fixed:
|
|
* boolean parameters to function invocations via RPC were not processed
|
|
correctly (#1976)
|
|
* VM CLI used too restrictive default call flags for loaded scripts (#1981)
|
|
* IPv6 check in NNS contract was out of date wrt C# implementation (#1969)
|
|
|
|
## 0.95.0 "Sharpness" (17 May 2021)
|
|
|
|
This version mostly implements N3 RC2 protocol changes (and is fully
|
|
RC2-compatible), but also brings NEP-11 CLI support and small improvements for
|
|
node operators.
|
|
|
|
Please note that this release is incompatible with 0.94.1 and there won't be
|
|
long-term support provided for it.

|
|
`CalledByEntry` in CLI and RPC (#1909)

|
## 0.94.1 "Channelization" (08 Apr 2021)
|
|
|
|
This is the second and much improved N3 RC1-compatible release. We've mostly
|
|
focused on documentation and examples with this release, so there is a number
|
|
of updates in this area including oracle contract example and NEP-11 NFT
|
|
contract example. At the same time proper testnet network revealed some
|
|
implementation inconsistencies between NeoGo and C# especially in oracle and
|
|
state validation services, so there are fixes for them also.
|
|
|
|
Protocol-wise this release is compatible with 0.94.0, but MPT structures have
|
|
changed and there are known state change differences for N3 RC1 testnet, so
|
|
you need to do full node resynchronization on update from 0.94.0. Some SDK
|
|
APIs have changed also improving developer experience, but they may affect
|
|
your code. We don't plan to make more of RC1-compatible releases (the protocol
|
|
has slightly changed already since the release).
|
|
|
|
New features:
|
|
* RPC (*Client).GetDesignatedByRole method to easily get node lists from
|
|
RoleManagement contract (#1855)
|
|
* `calculatenetworkfee` RPC method support (#1858)
|
|
* RPC client now has additional methods for NEP-11 contracts and specifically
|
|
for NNS native contract (#1857)
|
|
* contract deployment from multisig addresses (#1886)
|
|
|
|
Behavior changes:
|
|
* node roles for RoleManagement contract were moved into separate package
|
|
(#1855)
|
|
* NotaryVerificationPrice constant was moved into package of its own (#1855)
|
|
* testnet configuration now has proper N3 RC1 testnet magic (#1856)
|
|
* crypto.Verifiable interface was removed, now any hash.Hashable thing can be
|
|
verified (and signed, #1859)
|
|
* Network field was dropped from transaction.Transaction, block.Header,
|
|
payload.Extensible, state.MPTRoot, payload.P2PNotaryRequest and
|
|
network.Message, it was needed for proper hash calculations before recent
|
|
protocol changes (even though this field is not a part of serialized
|
|
representation of any of these elements), but now it's only used to
|
|
sign/verify data and doesn't affect hashing which allowed to simplify
|
|
interface here (#1859)
|
|
* RPC server now returns `StateRootInHeader` option in its `getversion`
|
|
request answers if it's used by the network (#1862)
|
|
* NNS record types were moved to separate package (#1857)
|
|
* MaxStorageKeyLen and MaxStorageValueLen constants were moved to storage
|
|
package from core (#1871)
|
|
* oracle service now accepts complete URL for other nodes RPC services (#1877)
|
|
|
|
Improvements:
|
|
* RPC (*Client).AddNetworkFee method is now more informative in some error
|
|
case (#1852)
|
|
* proper NEP-17 support in unit test contract (#1852)
|
|
* documentation updates for examples and services (#1854, #1890)
|
|
* syscall number is now printed for failed syscalls (#1874)
|
|
* better logging (#1883, #1889)
|
|
* Oracle native contract interop documentation extended (#1884)
|
|
* Oracle native contract interop extended with return codes and constants (#1884)
|
|
* oracle smart contract example (#1884)
|
|
* NEP-11 NFT smart contract example (#1891)
|
|
|
|
Bugs fixed:
|
|
* node could simultaneously try to connect to the same peer multiple times in
|
|
some cases (#1861)
|
|
* uniqueness is enforced now for other node addresses provided by peers (#1861)
|
|

functioning after restart if states were different (#1866)
|
|
* peers delivering P2P message with validated stateroot differing from local
|
|
one were disconnected (#1866)
|
|
* state dump comparing script was using old Ledger native contract ID (#1869)
|
|
* candidate registration check was made in different way from C# in native
|
|
NEO contract leading to different execution results for erroneous voting
|
|
transactions (#1869)
|
|
* state change dumps were different from C# node for erroneous voting
|
|
transactions even though contract's state was the same (#1869)
|
|
* arguments were not completely removed from stack in erroneous
|
|
Runtime.Notify calls leading to different stack state with C#
|
|
implementation (#1874)
|
|
* in case contract failed execution with THROW the node didn't print the
|
|
message from the contract properly (#1874)
|
|
* `getproof` RPC call output was not strictly compliant with C#
|
|
implementation (#1871)
|
|
* MPT node serialization and some constants were out of date wrt C#
|
|
implementation (#1871)
|

|
* state validation service could lock the system during shutdown, preventing

|
|
(#1880)
|
|
* oracle service was accepting http URLs instead of https (#1883)
|
|
* neofs URIs were subject to host validation in oracle service even though
|
|
there is no host there (#1883)
|
|

in the configuration (#1883)
|
|
* oracle response code was marshalled as integer into JSON (#1884)
|
|
* MPT could grow in memory unbounded (#1885)

## 0.94.0 "Tsessebe" (19 Mar 2021)
|
|
|
|
N3 RC1-compatible release is here. We've implemented all Neo protocol changes
|
|
(including state validation service and NeoFS support for oracles) and are
|
|
ready for testnet launch now, so that you could play with new native
|
|
contracts, VM instructions and other goodies RC1 brings with it. Some
|
|
usability improvements and documentation updates also went into this release
|
|
as well as a number of fixes stabilizing Notary subsystem (which is
|
|
NeoGo-specific protocol extension).
|
|
|
|
Please note that this release is incompatible with 0.93.0. We do plan to make
|
|
an update soon (with more examples and documentation), but there won't be
|
|
long-term support provided, Neo N3 is still on its way to mainnet (although
|
|
RC1 and testnet are major milestones on this route).

|
the header (#1792, #1840, #1841)

## 0.93.0 "Hyperproduction" (12 Feb 2021)
|
|
|
|
This is a 3.0.0-preview5 compatible release with important protocol changes,
|
|
improved smart contract interop interface for native contracts (it's much
|
|
easier now to use them) and complete Notary subsystem which is a NeoGo
|
|
experimental protocol extension for P2P signature collection.
|
|
|
|
Please note that this release is incompatible with 0.92.0 and there are no
|
|
plans for long-term support of it, Neo 3 is still changing and improving.
|
|
|
|
The release is tested with preview5 testnet data (and one of testnet CNs is
|
|
already a neo-go node) up to 48K blocks and it has exactly the same storage
|
|
data except for the Ledger contract that technically can differ between nodes
|
|
(it's not a part of state proper), and in case of neo-go it's intentionally
|
|
different (but this doesn't affect contract's functionality and state roots
|
|
compatibility).
|
|
|
|
New features:
|
|
* "ProtocolNotSupported" oracle response code (#1630)
|
|
* POPITEM VM opcode (#1670)
|
|
* CALLT VM opcode and contract tokens support (#1673)
|
|
* extensible P2P payloads (#1667, #1674, #1706, #1709)
|
|
* contract method overloading (#1689)
|
|
* oracle module (#1427, #1703)
|
|
* NNS native contract (#1678, #1712, #1721)
|
|
* complete P2P Notary subsytem (experimental protocol extension, use only on
|
|
private networks, #1658, #1726)
|
|
* Ledger native contract (#1696)
|
|
* `getblockheadercount` RPC call (#1718)
|
|
* native contract wrappers for Go smart contracts (#1702)
|
|
* `getnativecontracts` RPC call (#1724)
|
|
|
|
Behavior changes:
|
|
* VM CLI now supports and requires manifests to properly work with NEF files
|
|
(#1642)
|
|
* NEP-17-related CLI commands now output GAS balance as floating point numbers
|
|
(#1654)
|
|
* `--from` parameter can be omitted now for NEP-17 CLI transfers, the default
|
|
wallet address will be used in this case (#1655)
|
|
* native contracts now use more specific types for methods arguments (#1657)
|
|
* some native contract names and IDs have changed (#1622, #1660)
|
|
* NEF file is stored now in contract's state instead of script only which
|
|
also affects RPC calls and ContractManagement's interface
|

## 0.92.0 "Fermentation" (28 Dec 2020)
|
|
|
|
NeoGo project is closing year 2020 with 3.0.0-preview4 compatible release that
|
|
also has much improved performance, a lot of updates to compiler and SDK and
|
|
some experimental protocol extensions. This release also is the most tested
|
|
release of NeoGo ever, we've reached 83% code coverage (Neo 2.x only has
|
|
66%).
|
|
|
|
Please note that this release is incompatible with 0.91.0 and there are no
|
|
plans for long-term support of it, Neo 3 is still changing and improving.
|
|
|
|
Protocol-wise this release is tested with preview4 testnet (including working
|
|
in consensus with C# nodes) and it is compatible with it even though there are
|
|
some known storage change mismatches between NeoGo and C# (functionally the
|
|
contents is the same, this mismatch is caused by JSON handling differences and
|
|
needs to be addressed at the protocol level).
|

## 0.91.0 "Ululation" (18 August 2020)
|
|
|
|
We've updated NeoGo for 3.0.0-preview3 compatibility implementing all the
|
|
appropriate protocol changes as well as improving NeoGo-specific
|
|
components. This release brings with it significant changes for smart
|
|
contracts, both in terms of Neo protocol changes (no more there is a single
|
|
entry point! execution environment has also changed in lots of ways) and Go
|
|
smart contract compiler updates and fixes.
|
|
|
|
Please note that this release is incompatible with 0.90.0 and there will be no
|
|
long-term support provided for it, Neo 3 is still changing and
|
|
improving. If you have any wallets used with 0.90.0 release you'll need to
|
|
regenerate them from private keys because of changes to verification scripts
|
|
that also changed hashes and addresses.
|
|
|
|
But nonetheless it is tested to be compatible with preview3 testnet for up to
|
|
68K of blocks in terms of storage changes, with neo-debugger for debug data
|
|
produced by the compiler and with consensus process for heterogeneous setups
|
|
(like 2 neo-go CNs with 2 C# CNs).
|
|
|
|
New features:
|
|
* secp256k1 signature checks added to interop functions

|
|
functions, #918)

|
|
crypto.RIPEMD160 interop function, #918, #1193)
|
|
* "NotFound" P2P message (#1135, #1333)
|
|
* base64 encoding/decoding interop functions (binary.Base64Encode and
|
|
binary.Base64Decode, #1187)
|
|

|
|
implemented (#1187)
|
|

|
|
types in smart contracts (#1218)

|
|
smart contracts in Go (#1221)
|
|
* exceptions support in VM (#885)
|
|
* CLI conversion utility functions for addresses/hashes/etc (#1207, #1258)
|
|
* multitransfer transactions now can be generated with RPC client or CLI
|
|
(#940, #1260)

|
|
interop functions, #1197)
|
|
* MPT implementation was added (#1235)
|
|
* Policy native contract now also contains MaxBlockSystemFee setting (#1195)
|
|

|
|
* limited pointer support was added to the compiler (#1247)
|
|

|
|
|
|
Behavior changes:
|
|
* crypto.ECDsaVerify interop function was renamed to
|
|
crypto.ECDsaSecp256r1Verify now that we have support for secp256k1 curve
|
|
(#918)
|
|
* many RPC requests/responses changed names used for data fields (#1169)
|
|
* runtime.Notify interop function now requires a mandatory UTF8 name
|
|
parameter (#1052) and this name can be used to filter notifications (#1266)
|
|
* sendrawtransaction and submitblock RPC calls now return a hash instead of
|
|
boolean value in case of success (#1216)
|
|
* System.Runtime.Log syscall now only accepts valid UTF8 strings no longer
|
|
than 1024 bytes (#1218)

|
|
bytes (#1221)
|
|
* PUSHA instruction now works with relative code offset (#1226)
|
|
* EQUAL instruction no longer does type conversions, so that values of
|
|
different types are always unequal (#1225)
|
|
* verification scripts now can't use more than 0.5 GAS (#1202)
|
|
* contracts no longer have single entry point, rather they export a set of
|
|
methods with specific offsets. Go smart contract compiler has been changed

accordingly to add all exported (as in Go) methods to the manifest
|
|
(but with the first letter being lowercased to match NEP-5 expections,
|
|
#1228). Please also refer to examples changes to better see how it affects
|
|
contracts, manifests and configuration files (#1296)
|
|
* native contracts are now called via Neo.Native.Call syscall (#1191)
|
|

|
|
#1255)

|
|
settings) or AllowModifyStates (to change setting) flags (#1254)

|
|
Cosigners, a Signer can have FeeOnly or any other regular witness scope
|
|
(#1184)

|
standby validators are no longer being registered by default (#867, #1300)
|
|
* Go 1.13+ is now required to build neo-go (#1281)
|
|
* public contract methods now always return some value and this is being
|
|
checked by the VM (#1196, #1331, #1332)
|
|
* runtime interop package now exports triggers as proper constants rather
|
|
than functions (#1299)

## 0.90.0 "Tantalization" (14 July 2020)
|
|
|
|
The first Neo 3 compatible release of neo-go! We've targeted to make it
|
|
compatible with preview2 release of Neo 3, so it only contains features
|
|
available there, but at the same time this makes the node more useful until we
|
|
have some more up to date reference version. It's a completely different
|
|
network, so almost everything has changed and it's hard to describe it with
|
|
the same level of details we usually do (but we'll provide them for subsequent
|
|
releases where the changeset is going to be lower in size). Please note that
|
|
this is a preview-level release and there won't be long-term support provided
|
|
for it, Neo 3 is evolving and the next release won't be compatible with this
|
|
one.
|
|
|
|
Main Neo 3 features in this release:
|
|
* no UTXO
|
|
* native contracts
|
|
* new VM
|
|
* scoped witnesses for transaction
|
|
* updated interop/syscalls set
|
|
* contract manifests
|
|
* more efficient P2P protocol
|
|
|
|
Things that have also changed:
|
|
* transaction format
|
|
* block format
|
|
* address format
|
|
* wallets
|
|
* RPC protocol
|
|
* notification subsystem
|
|
* executable format output for compiler
|
|
|
|
Compatibility level of this neo-go release:
|
|
* identical storage changes compared to C# node for 378K blocks of preview2
|
|
testnet
|
|
* debugging info produced is compatible with preview2-compatible neo-debugger
|
|
* running consensus nodes in heterogeneous setup is possible (2 neo-go CNs
|
|
with 2 C# CNs, for example)
|
|
|
|
Changes specific to neo-go:
|
|
* some CLI parameters like wallet path or RPC endpoint URL have been unified
|
|
across all commands and thus have changed in some of them (refer to CLI
|
|
help for details)
|
|
* as an extension we support post-preview2 cosigners parameter for
|
|
invokefunction RPC calls (see neo-project/neo-modules#260)
|
|
* Go compiler now supports comparisons with nil properly
|
|
* we no longer provide bootstrapping 6k block dump for private networks, you
|
|
have 30000000 GAS right in the genesis block and it's not hard to make use
|
|
of it (see
|
|
[neo-go-sc-wrkshp](https://github.com/nspcc-dev/neo-go-sc-wrkshp) for an
|
|
example of how to use it)
|
|
* we have a conversion tool for your old Neo 2 wallets (`wallet convert`
|
|
command), so you can reuse keys on Neo 3 networks
|
|
* util.Equals interop function may not function the way you expect it to due
|
|
to Neo VM changes, it still is an EQUAL opcode though. This interop may be
|
|
removed in the future.

Please refer to the [master-2.x branch
|
|
CHANGELOG](https://github.com/nspcc-dev/neo-go/tree/master-2.x/CHANGELOG.md)
|
|
for versions prior to 0.90.0 (that are Neo 2 compatible, unlike 0.90.0+ that
|
|
are Neo 3 compatible).
