# Changelog
|
|
|
|
This document outlines major changes between releases.
|
|
|
|
## 0.74.0 "Comprehension" (17 Mar 2020)
|
|
|
|
Functionally complete NEO 2.0 node implementation, this release can be used as
|
|
a drop-in replacement for C# node in any setting. It features full RPC
|
|
functionality support and full set of wallet operations. As usual, there
|
|
also was a number of bugs fixed, the node stability improved and some great
|
|
optimizations were also done (especially concentrated around DB interactions),
|
|
so even though this release has more functionality than ever (and it stores a
|
|
lot more chain data than ever) it at the same time imports blocks faster than
|
|
the previous one.
|
|
|
|
Of course we will make additional maintenance releases for NEO 2.0 when
|
|
needed, but following this release we'll concentrate more on NEO 3.0 features
|
|
and catching up with recent community developments around that.
|

|
|
notification generated by the invocation transaction (#650)
|
|
|
|
## 0.72.0 "Crystallization" (06 Feb 2020)
|
|
|
|
Starting at the end of the year 2019 we've spent a lot of effort to
|
|
stress-test our node with transaction load and this allowed us to uncover
|
|
some problems in various parts of the system. This release addresses all of
|
|
them and brings with it updated networking, consensus and mempool components
|
|
that can handle quite substantial transaction traffic and successfully produce
|
|
new blocks while being stressed. There are also important updates in VM that
|
|
fix incompatibilities with C# node and interesting improvements in compiler
|
|
based on our experience porting neofs smart contract to Go.

## 0.71.0 "Celebration" (30 Dec 2019)
|
|
|
|
Version 0.71.0 ends the year 2019 of neo-go development with a solid release
|
|
that adds support for pprof, implements all missing interoperability
|
|
functions, improves performance and as usual fixes some bugs. This is also the
|
|
first release with a test coverage of more than 60% which is a significant
|
|
milestone in our trend to improve code quality and testing. Back in August
|
|
2019 when NSPCC had started neo-go developement the project only had a
|
|
coverage of 45% and even though a lot of code has been added since we're
|
|
improving this metrics with every release.
|
|
|
|
New features:
|
|
* pprof support (disabled by default, #536)
|
|
* compiler now supports assignments to an element of slice using variable
|
|
index (#564)
|
|
* hashed 4-byte IDs support for SYSCALL instruction (#565)
|
|
* remainder ('%') operator support in compiler (#563)
|
|
* Neo.Witness.GetVerificationScript and Neo.InvocationTransaction.GetScript
|
|
interop functions (#421)
|
|
* Neo.Iterator.*, Neo.Enumerator.* and Neo.Storage.Find interops (#422)
|
|
* tuple return support in compiler (#562)
|
|
* `getblocks` P2P command implementation (#577)
|
|
|
|
Behaviour changes:
|
|
* `Monitoring` config section changed its name to `Prometheus` because of
|
|
pprof addition (#536)
|
|
* `db dump` command now also writes the block number zero by default to
|
|
comply with ImportBlocks format (#582)
|
|
* `skip` parameter was renamed to `start` in the `db dump` command (#582)
|
|
* `db restore` now skips the genesis block in the dump if starting to import
|
|
into the new DB and if this block matches the one generated on blockchain
|
|
init (#582)
|
|
|
|
Improvements:
|
|
* VM optimizations (#558, #559, #565, #572)
|
|
* top block caching in core to improve dApps performance (#572)
|
|
* transaction's TXType can now be JSON-unmarshalled (#575)
|
|
* `crypto` package no longer exports AES functions (#579)
|
|
* merkle tree functions and structures were moved into the `hash` package
|
|
(#579)
|
|
* base58 functionality was moved into its own package from `crypto` (#579)
|
|
* `Uint160DecodeAddress` and `AddressFromUint160` functions were moved out of
|
|
`crypto` into their own package (#579)
|
|
* `address` package now can be configured to use different prefixes (#579)
|
|
|
|
Bugs fixed:
|
|
* wrong INVERT instruction behaviour for converted values (#561)
|
|
* wrong DUP behaviour when the next instruction doesn't convert the value
|
|
(#561)
|
|
* OVER and PICK implementations didn't properly duplicate stack items (#561)
|
|
* PICKITEM instruction failed to duplicate picked items (#561)
|
|
* `getblock` RPC call was not answering with full hex-encoded block (#575)
|
|
* base58.CheckDecode was decoding values with leading zeroes in a wrong way
|
|
(#579)
|
|
* decoding wrong public key could succeed (#579)
|
|
* consensus payload verification was inconsistent with other verification
|
|
code (#555)
|
|
* DB dump was using wrong format in release 0.70.1 (#582)
|
|
* DB restorer was not properly counting skipped blocks which could lead to
|
|
bogus error being reported (#582)
|
|
* the DB was not closed properly on error during DB restore (#582)
|
|
* NPE in consensus (#583)
|
|
|
|
## 0.70.1 "Centrifugation" (16 Dec 2019)
|
|
|
|
Release 0.70.1 brings no new functionality focusing on internal node
|
|
improvements instead. Some bugs were fixed, refactoring was done and
|
|
performance was improved substantially.
|
|
|
|
Behaviour changes:
|
|
* as with the previous release, this one changes the database format, so you
|
|
need to resynchronize your nodes
|
|
* code testing will fail if you're not to checkout submodules (we have one
|
|
with neo-vm tests, #543)
|
|
|
|
Improvements:

## 0.62.0 "Commotion" (07 Nov 2019)
|
|
|
|
Release 0.62.0 finishes one very important work some pieces of which were
|
|
gradually rolled out in previous releases --- it integrates all neo-vm project
|
|
JSON-based tests for NEO 2.0 C# VM and runs them successfully against neo-go
|
|
VM. There are also important bug fixes based on mainnet nodes deployment
|
|
experience and additional configuration options.
|
|
|
|
New Features:
|
|
* implemented `Runtime.Serialize` and `Runtime.Deserialize` syscalls (#419)

|
|
connections that the node will try to establish when it goes below the
|
|
MinPeers setting (#478)
|
|
* `LogPath` configuration parameter to write logs into some file and not to
|
|
stdout (#460), not enabled by default
|
|
* `Address` configuration parameter to specify the address to bind to (#460),
|
|
not enabled by default
|
|
|
|
Behavior changes:
|
|

|
|
* multiple connections to the same peer are disallowed now (as they are in C#
|
|
node (#478))

|
|
configurations and limited to 10 for privnet (#478)

|
* implemented missing VM constraints: stack item number limitation (#462) and
|
|
integer size checks (#484, #373)

|
|
remaining incompabitibilities (#196)

|
|
differs from C# interpretation of `getblockcount` (#471)

|
|
to the hash, while C# node does it

|
|
* data race in `Server` structure fields access (#478)
|
|

|
|
persist anything (#481)
|
|
* current header height was not stored in the DB when starting a new
|
|
blockchain which lead to node failures on restart (#481)
|
|
* crash on node restart if no header hashes were written into the DB (#481)
|
|
|

|
|
compile Go code with `-c` parameter (previously is was done by default),
|
|
`inspect` subcommand was removed from `neo-go vm` (it dumped avm files in
|
|
previous release) (#463)
|
|
* the default minimum peers was reduced to 3 for privnet setups to avoid
|
|
useless reconnections to only 4 available nodes
|
|
* RPC service now has its own section in configuration, update your
|
|
configurations (#469)

|
|
block verification, improved and fixed transaction verifications,
|
|
implementation of most of interop functions and VM improvements. Block

(#418)
|
|
* blocks are now completely verified when added to the chain (if not
|
|
configured otherwise; #12, #418)
|
|
|
|
Behavior changes:
|
|

|
|
have symmetry now in AddBlock/GetBlock APIs; #414, #366)
|
|
* removed duplicating batch structures from BoltDB and Redis code, now all of
|
|
them use the same batch as MemoryStore does (#414)

|
|
(#417)
|
|
* Store interface now has Delete method (#418)

(#418)
|
|
* Batch interface doesn't have Len method now as it's not used at all (#418)
|
|
* New*FromRawBytes functions were renamed to New*FromASN1 in the keys

|
|
(including temporary stores for transaction processing) and batched
|
|
persistence (#425)

|
|
|
Bugs fixed:
|
|
* useless persistence failure message printed with no error (#409)
|
|
* persistence error message being printed twice (#409)
|
|
* segmentation fault upon receival of message that is not currently handled
|
|
properly (like "consensus" message; #409)
|
|
* BoltDB's Put for a batch wasn't copying data which could lead to data
|
|
corruption (#409)
|
|
* APPEND instruction applied to struct element was not copying it like neo-vm
|
|
does (#405, part of #196 work)
|
|
* EQUAL instruction was comparing array contents, while it should've compared
|
|
references (#405, part of #196 work)

|
* SUBSTR instruction was failing for out of bounds length parameters while it
|
|
should've truncated them to string length (#406, part of #196 work)

## 0.50.0 "Consolidation" (19 Sep 2019)
|
|
|
|
The first release from the new team focuses on bringing all related
|
|
development effort into one codebase, refactoring things, fixing some
|
|
long-standing bugs and adding new functionality. This release merges two
|
|
radically different development branches --- `dev` and `master` that were
|
|
present in the project (along with all associated pull requests) and also
|
|
brings in changes made to the compiler in the neo-storm project.
|
|
|
|
New features:
|
|
* configurable storage backends supporting LevelDB, in-memory DB (for
|
|
testing) and Redis
|
|
* BoltDB support for storage backend
|
|
* updated and extended interop APIs (thanks to neo-storm)
|
|
|
|
Notable behavior changes:
|
|
* the default configuration for privnet was changed to use ports 20331 and
|
|
20332 so that it doesn't clash with the default dockerized neo-privnet
|
|
setups
|
|
* the default configuration path was changed from `../config` to `./config`,
|
|
at this stage it makes life a bit easier for development, later this will
|
|
be changed to some sane default for production version
|
|
* VM CLI now supports type inference for `run` parameters (you don't need to
|
|
specify types explicitly in most of the cases) and treats `operation`
|
|
parameter as mandatory if anything is passed to `run`
|
|
|
|
VM improvements:
|
|
* added implementation for `EQUAL`, `NZ`, `PICK`, `TUCK`, `XDROP`, `INVERT`,
|
|
`CAT`, `SUBSTR`, `LEFT`, `RIGHT`, `UNPACK`, `REVERSE`, `REMOVE`
|
|
* expanded tests
|
|
* better error messages for different erroneous code
|
|
* implemented item conversions following neo-vm behavior: array to/from
|
|
struct, bigint to/from boolean, anything to bytearray and anything to
|
|
boolean
|
|
* improved compatibility with neo-vm (#394)
|
|
|
|
Technical improvements:
|
|
* switched to Go 1.12+
|
|
* gofmt, golint (#213)
|
|
* fixed and improved CircleCI builds
|
|
* removed internal rfc6969 package (#285)
|
|
* refactored util/crypto/io packages, removed a lot of duplicating code
|
|
* updated READMEs and user-level documents
|
|
* update Makefile with useful targets
|
|
* dropped internal base58 implementation (#355)
|
|
* updated default seed lists for mainnet and testnet from neo-cli
|
|
|
|
Bugs fixed:
|
|
* a lot of compiler fixes from neo-storm
|
|
* data access race in memory-backed storage backend (#313)
|
|
* wrong comparison opcode emitted by compiler (#294)
|
|
* decoding error in `publish` transactions (#179)
|
|
* decoding error in `invocation` transactions (#173)
|
|
* panic in `state` transaction decoding
|
|
* double VM run from CLI (#96)
|
|
* non-constant time crypto (#245)
|
|
* APPEND pushed value on the stack and worked for bytearrays (#391)
|
|
* reading overlapping hash blocks from the DB leading to blockchain state
|
|
neo-go couldn't recover from (#393)
|
|
* codegen for `append()` wasn't type-aware and emitted wrong code (#395)
|
|
* node wasn't trying to reconnect to other node if connection failed (#390)
|
|
* stricly follow handshare procedure (#396)
|
|
* leaked connections if disconnect happened before handshake completed (#396)
|
|
|
|
### Inherited unreleased changes
|
|
|
|
Some changes were also done before transition to the new team, highlights are:
|
|
* improved RPC testing
|
|
* implemented `getaccountstate`, `validateaddress`, `getrawtransaction` and
|
|
`sendrawtransaction` RPC methods in server
|
|
* fixed `getaccountstate` RPC implementation
|
|
* implemented graceful blockchain shutdown with proper DB closing
|
|

## 0.45.14 (not really released, 05 Dec 2018)
|
|
|
|
This one can technically be found in the git history and attributed to commit
|
|
fa1da2cb917cf4dfccbe49d44c5741eec0e0bb65, but it has no tag in the repository
|
|
and so can't count as a properly released thing. Still it can be marked as a
|
|
point in history with the following changes relative to 0.44.10:
|
|
* switched to Go modules for dependency management
|
|
* various optimizations for basic structures like Uin160/Uint256/Fixed8
|
|
* improved testing
|
|
* added support for `invoke` method in RPC client
|
|
* implemented `getassetstate` in RPC server
|
|
* fixed NEP2Encrypt and added tests
|
|
* added `NewPrivateKeyFromRawBytes` function to the `wallet` package
|

## 0.44.10 (27 Sep 2018)
|
|
|
|
This is the last one tagged in the repository, so it's considered as the last
|
|
one properly released before 0.50+. Releases up to 0.44.10 seem to be made in
|
|
automated fashion and you can find their [changes on
|
|
GitHub](https://github.com/nspcc-dev/neo-go/releases).
