First stable Istanbul release passing all StateTests and BlockchainTests from the official Ethereum test suite v7.0.0-beta.1. Test suite conformance have been reached along work on PR #607 (thanks @s1na!) and there were several fixes along the way, so it is strongly recommended that
you upgrade from the first beta Istanbul release v4.1.0.

Istanbul Related Fixes

  • Refund counter has been moved from the EEI to the EVM module, PR #612, gasRefund is re-added to the execResult in the EVM module at the end of message execution in EVM to remain (for the most part) backwards-compatible in the release
  • Fixed blake2f precompile for rounds > 0x4000000
  • Fixed issues causing RevertPrecompiled* test failures
  • Fixed an issue where the RIPEMD precompile has to remain touched even when the call reverts and be considered for deletion, see EIP-716 for context
  • Updated ethereumjs-block to v2.2.1
  • Updated ethereumjs-blockchain to v4.0.2
  • Limited ethereumjs-util from ^6.1.0 to ~6.1.0
  • Hardfork-related fixes in test runners and test utilities

Other Changes

  • Introduction of a new caching mechanism to cache calls towards promisify being present in hot paths (performance optimization), PR #600
  • Renamed some missing result.return to result.returnValue on EVM execution in examples, PR #604
  • Improved event documentation, PR #601
