| # Changelog | ||
|
|
||
| This document outlines major changes between releases. | ||
|
|
||
| ## 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). |
