• https://www.parity.io/security-alert-parity-ethereum-03-02/

The full list of included changes:

• Version: bump beta to 2.3.2 (#10283)
• Additional tests for uint deserialization. (#10279) (#10280)
• Backport #10285 to beta (#10286)

Parity-Ethereum v2.3.1 (2019-02-01)

Parity-Ethereum 2.3.1-beta is a consensus-relevant release that enables St. Petersfork on:

• Ethereum Block 7280000 (along with Constantinople)
• Kovan Block 10255201
• Ropsten Block 4939394
• POA Sokol Block 7026400

In addition to this, Constantinople is cancelled for the POA Core network. Upgrading is mandatory for clients on any of these chains.

The full list of included changes:

• Backports for beta 2.3.1 (#10225)
  • Fix cannot recursively call into Core issue (#10144)
  • Update for Android cross-compilation. (#10180)
  • Fix cannot recursively call into Core - Part 2 (#10195)

  • Enable St-Peters-Fork ("Constantinople Fix") (#10223)
• Beta: Macos heapsize force jemalloc (#10234) (#10259)

Parity-Ethereum v2.3.0 (2019-01-16)

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)
  • Read more: Security Alert: Ethereum Constantinople Postponement
• 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.
