v0.31.2

Fixed

• [Dump] Stop TxStack EventStream consumer from rejecting events from dump/restored chain because they lack tx Envelopes (as they are intended to to keep dump format minimal)
• [Genesis] Fix hash instability introduced by accidentally removing omitempty from AppHash in genesis

Added

• [Vent] Implement throttling on Ethereum Vent consumer via --max-request-rate=<requests / time base> flag to 'vent start'

v0.31.1

Changed

• [Repo] main branch replaces master as per Hyperledger TSC guidelines

Fixed

• [Docker] Make sure default testnet mode works when running docker images
• [Vent] Use appropriately sized database integral types for EVM integer types (i.e. numeric for uint64 and bigger)
• [Vent] Ethereum block consumer now correctly reads to an inclusive block batch end height
• [Web3] Handle integer ChainID for web3 consistently; return hex-encoded numeric value from web3 RPC, also allow overriding of genesis-hash derived ChainID so Burrow can be connected with from metamask

Added

• [Build] Build dev docker and JS releases by force pushing to prerelease branch
• [Vent] Expose BlockConsumerConfig to adjust backoff and read characteristics
• [Vent] Add vent-side continuity test over blocks (to double-check exactly once delivery of events)

v0.31.0

Changed

• [Tendermint] Upgraded to Tendermint 0.34.3
• [Docker] Image will now start testnet by default

Added

• [Vent] Added support for building Vent SQL tables from Ethereum web3 JSONRPC chains (useful for oracles/state channels with layer 1)
• [Vent] Added Status to healthcheck endpoint on Vent
• [Natives] Implemented ecrecover using btcec (revised key handling)
• [Engine] Implement cross-engine dispatch
• [WASM] Implement cross-engine calls and calls to precompiles
• [WASM] Significantly extend eWASM support and implement functions
• [WASM] Add printing debug functions
• [WASM] Implement CREATE, GETTXGASPRICE, GETBLOCKDIFFICULTY, SELFDESTRUCT eWASM functions (thanks Yoongbok Lee!)
• [WASM/JS] JS library supports deploying WASM code
• [Deploy] Can specify WASM in playbook
• [EVM] Implement CHAINID and DIFFICULTY opcodes
• [Query] PEG query grammar now supports Not ("NOT") and NotEqual ("!=") operators

Fixed

• [Deploy] Fix flaky parallel tests
• [EVM] Use correct opcode for create2 (thanks Vitali Grabovski!)
• [ABI] Check length of input before decoding (thanks Tri-stone!)
• [WASM] Constructor argument handling
• [RLP] Incorrect use of offsets for longer bytes strings
• [RLP] Use minimal encoding for length prefixes (no leading zeros)
• [Web3] Generate correct encoding hash for RawTx (ChainID in hash digest but not payload)
• [Web3] Generate canonical weird Ethereum hex
• [State] Fix read concurrency in RWTree (on which state is based) removing need for CallSim lock workaround

Security

• Updated elliptic JS dep to 6.5.3
• Updated lodash to 4.17.19

v0.30.5

Added

• [Vent] Add BytesToHex flag on projection field mappings that causes bytes fields (e.g. bytes32) solidity fields to be hex-encoded and mapped to varchar(64) rather than bytea/blob columns in postgres/sqlite

v0.30.4

Added

• [Build] Added Helm chart
• [State] Account now has OpcodeBitset field to support upcoming EVM fixes

Fixed

• [JS] Github actions release of JS lib

v0.30.3

Added

• [CLI] Made previously internal Solidity Go fixtures compilation available through 'burrow compile'
• [TS] Default ts client interface implementation

v0.30.2

Fixed

• [RPC] add mutex to callSim and callCode

v0.30.1

Fixed

• [CLI/Tx] Unbond formulation now specifies amount

v0.30.0

Changed

• [JS] Partial rewrite of client API in typescript

Fixed

• [State] Blockchain now commits initial AppHash to avoid IAVL panic

v0.29.8

Fixed

• [ABI] Fix failure to convert crypto.Address to EVMAddress (#1326)
