Eris-DB changelog

0.12.0-RC3

This release marks the start of Eris-DB as the full permissioned blockchain node of the Eris platform with the Tendermint permissioned consensus engine. This involved significant refactoring of almost all parts of the code, but provides a solid foundation to build the next generation of advanced permissioned smart contract blockchains.

Many changes are under the hood but here are the main externally visible changes:

• Features and improvements

  • Upgrade to Tendermint 0.6.0 in-process consensus
  • Support DELEGATECALL opcode in Ethereum Virtual Machine (important for solidity library calls)
  • ARM support
  • Docker image size reduced
  • Introduction of eris-client companion library for interacting with eris:db
  • Improved single configuration file for all components written by eris-cm
  • Allow multiple event subscriptions from same host under rpc/tendermint

• Tool changes

  • Use glide instead of godeps for dependencies

• Testing

  • integration tests over simulated RPC calls
  • significantly improved unit tests
  • the ethereum virtual machine and the consensus engine are now top-level components and are exposed to continuous integration tests

• Bugfixes (incomplete list)

  • [EVM] Fix calculation of child CALL gaslimit (allowing solidity library calls to work properly)
  • [RPC/v0] Fix blocking event subscription in transactAndHold (preventing return in Javascript libraries)
  • [Blockchain] Fix getBlocks to respect block height cap
