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).
