# Changelog
|
|
|
|
This document outlines major changes between releases.
|
|
|
|
## 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
|
|
Neo.Crypto.CheckMultisigWithECDsaSecp256k1 syscalls,
|
|
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)
|
|
* storage.PutEx interop (System.Storage.PutEx syscall) is now available to
|
|
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)
|
|
* System.Callback.* syscalls for callback creation and execution (callback.*
|
|
interop functions, #1197)
|
|
* MPT implementation was added (#1235)
|
|
* Policy native contract now also contains MaxBlockSystemFee setting (#1195)
|
|

|
|
* voting support in CLI (#1206, #1286)
|
|
|
|
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)
|
|

|
|
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)
|
|

|
|
(#1198)
|
|
* stack items now can be converted to/from JSON natively (without
|
|
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)
|
|
* Transaction now has Signers field unifying Sender (the first Signer) and
|
|
Cosigners, a Signer can have FeeOnly or any other regular witness scope
|
|
(#1184)
|
|
* verification scripts no longer have access to blockchain's state (#1277)
|
|
* governance scheme was changed to delegated committee-based one. The number
|
|
of validators is now specified with ValidatorsCount configuration option,
|
|
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

|
|
|

|
|
results (#1236)

|
|

|
|
be used for BFT-compliant "m out of n" multisignature script generation
|
|
(#1300)

|
|
#1300)

## 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.

for versions prior to 0.90.0 (that are Neo 2 compatible, unlike 0.90.0+ that
|
|
are Neo 3 compatible).
