Parity-Ethereum v2.3.0 (2018-01-16)

Parity-Ethereum 2.3.0-beta is a consensus-relevant security release that reverts Constantinople on the Ethereum network. Upgrading is mandatory for Ethereum, and strongly recommended for other networks.

  • Consensus - Ethereum Network: Pull Constantinople protocol upgrade on Ethereum (#10189)
  • Networking - All networks: Ping nodes from discovery (#10167)
  • Wasm - Kovan Network: Update pwasm-utils to 0.6.1 (#10134)

Other notable changes:

  • Existing blocks in the database are now kept when restoring a Snapshot. (#8643)
  • Block and transaction propagation is improved significantly. (#9954)
  • The ERC-191 Signed Data Standard is now supported by personal_sign191. (#9701)
  • Add support for ERC-191/712 eth_signTypedData as a standard for machine-verifiable and human-readable typed data signing with Ethereum keys. (#9631)
  • Add support for ERC-1186 eth_getProof (#9001)
  • Add experimental RPCs flag to enable ERC-191, ERC-712, and ERC-1186 APIs via --jsonrpc-experimental (#9928)
  • Make CALLCODE to trace value to be the code address. (#9881)

Configuration changes:

  • The EIP-98 transition is now disabled by default. If you previously had no eip98transition specified in your chain specification, you would enable this now manually on block 0x0. (#9955)
  • Also, unknown fields in chain specs are now rejected. (#9972)
  • The Tendermint engine was removed from Parity Ethereum and is no longer available and maintained. (#9980)
  • Ropsten testnet data and keys moved from test/ to ropsten/ subdir. To reuse your old keys and data either copy or symlink them to the new location. (#10123)
  • Strict empty steps validation (#10041)
    • If you have a chain withempty_steps already running, some blocks most likely contain non-strict entries (unordered or duplicated empty steps). In this release strict_empty_steps_transition is enabled by default at block 0x0 for any chain with empty_steps.
    • If your network uses empty_steps you must (A) plan a hard fork and change strict_empty_steps_transition to the desired fork block and (B) update the clients of the whole network to 2.2.7-stable / 2.3.0-beta. If for some reason you don't want to do this please setstrict_empty_steps_transition to 0xfffffffff to disable it.

Note: This release marks Parity 2.3 as beta. All versions of Parity 2.2 are now considered stable.
