## 0.95.0 "Sharpness" (17 May 2021)
|
|

RC2-compatible), but also brings NEP11 CLI support and small improvements for
|
|
node operators.

|
## 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)
|
|
* stateroot message hash wasn't calculated the same way as in C# (#1859)

|
|
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
|
|
proper node exit (#1877)
|
|
* state validation and oracle services were started before node reaching full
|
|
synchronization which could lead to excessive useless traffic (#1877)
|
|
* some native contract calls in function arguments could be miscompiled
|
|
(#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)
|
|
* neofs URI scheme was differing from C# implementation (#1883)

in the configuration (#1883)
|
|
* oracle response code was marshalled as integer into JSON (#1884)
|
|

## 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).

## 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)

## 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
|
|
(Neo.Crypto.VerifyWithECDsaSecp256k1 and

|
|
crypto.ECDsaSecp256k1Verify and crypto.ECDSASecp256k1CheckMultisig interop
|
|
functions, #918)
|
|
* RIPEMD160 hash added to interop functions (Neo.Crypto.RIPEMD160 syscall,
|
|
crypto.RIPEMD160 interop function, #918, #1193)
|
|
* "NotFound" P2P message (#1135, #1333)
|
|
* base64 encoding/decoding interop functions (binary.Base64Encode and
|
|
binary.Base64Decode, #1187)
|
|
* new contract.GetCallFlags interop (System.Contract.GetCallFlags syscall)
|
|
implemented (#1187)
|
|
* it is possible now to create iterators and enumerators over primitive VM
|
|
types in smart contracts (#1218)
|
|
* runtime.Platform interop (System.Runtime.Platform syscall) is now available
|
|
to smart contracts in Go (#1218)

|
|

|
|
* CLI conversion utility functions for addresses/hashes/etc (#1207, #1258)
|
|
* multitransfer transactions now can be generated with RPC client or CLI
|
|
(#940, #1260)

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

|
|
crypto.ECDsaSecp256r1Verify now that we have support for secp256k1 curve
|
|
(#918)
|
|
* many RPC requests/responses changed names used for data fields (#1169)

|
|
boolean value in case of success (#1216)

|
|
* 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)
|
|
* NEF files now use double SHA256 for checksums (#1203)
|
|
* VM's map keys and contract methods now can only contain valid UTF-8 strings
|
|
(#1198)

|
|
smartcontract.ContractParameters intermediate) which is now used for
|
|
invoke* RPC calls and application execution logs (#1242, #1317)
|
|
* invoking Policy native contracts now requires AllowsStates (to get
|
|
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)
|
|
* RPC client no longer has SetWIF/WIF methods that didn't do anything useful
|
|
anyway (#1328)
|
|
|
|
Improvements:

|
|
crypto.ECDSASecp256r1CheckMultisig interop function (#1175)

|
|
* notifications can't be changed now by a contract after emitting them
|
|

## 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).
