Parity-Ethereum v2.2.5 (2018-12-14)

Parity-Ethereum 2.2.5-beta is an important release that introduces Constantinople fork at block 7080000 on Mainnet. This release also contains a fix for chains using AuRa + EmptySteps. Read carefully if this applies to you. If you have a chain withempty_steps already running, some blocks most likely contain non-strict entries (unordered or duplicated empty steps). In this releasestrict_empty_steps_transition is enabled by default at block 0 for any chain with empty_steps. If your network uses empty_steps you must:

• plan a hard fork and change strict_empty_steps_transition to the desire fork block
• update the clients of the whole network to 2.2.5-beta / 2.1.10-stable. If for some reason you don't want to do this please setstrict_empty_steps_transition to 0xfffffffff to disable it.

The full list of included changes:

• Backports for beta 2.2.5 (#10047)
  • Bump beta to 2.2.5 (#10047)
  • Fix empty steps (#9939)
    • Prevent sending empty step message twice
    • Prevent sending empty step and then block in the same step
    • Don't accept double empty steps
    • Do basic validation of self-sealed blocks
  • Strict empty steps validation (#10041)
    • Enables strict verification of empty steps - there can be no duplicates and empty steps should be ordered inside the seal.
    • Note that authorities won't produce invalid seals after #9939, this PR just adds verification to the seal to prevent forging incorrect blocks and potentially causing consensus issues.
    • This features is enabled by default so any AuRa + EmptySteps chain should set strict_empty_steps_transition fork block number in their spec and upgrade to v2.2.5-beta or v2.1.10-stable.
  • ethcore: enable constantinople on ethereum (#10031)
    • ethcore: change blockreward to 2e18 for foundation after constantinople
    • ethcore: delay diff bomb by 2e6 blocks for foundation after constantinople
    • ethcore: enable eip-{145,1014,1052,1283} for foundation after constantinople
  • Change test miner max memory to malloc reports. (#10024)
  • Fix: test corpus_inaccessible panic (#10019)

Parity-Ethereum v2.2.2 (2018-11-29)

Parity-Ethereum 2.2.2-beta is an exciting release. Among others, it improves sync performance, peering stability, block propagation, and transaction propagation times. Also, a warp-sync no longer removes existing blocks from the database, but rather reuses locally available information to decrease sync times and reduces required bandwidth.

Before upgrading to 2.2.2, please also verify the validity of your chain specs. Parity Ethereum now denies unknown fields in the specification. To do this, use the chainspec tool:

cargo build --release -p chainspec
./target/release/chainspec /path/to/spec.json

Last but not least, JSONRPC APIs which are not yet accepted as an EIP in the eth, personal, or web3 namespace, are now considere experimental as their final specification might change in future. These APIs have to be manually enabled by explicitly running --jsonrpc-experimental.

• Backports For beta 2.2.2 (#9976)
  • Version: bump beta to 2.2.2
  • Add experimental RPCs flag (#9928)

Parity-Ethereum v2.2.1 (2018-11-15)

Parity-Ethereum 2.2.1-beta is the first v2.2 release, and might introduce features that break previous work flows, among others:

• Prevent zero network ID (#9763) and drop support for Olympic testnet (#9801): The Olympic test net is dead for years and never used a chain ID but network ID zero. Parity Ethereum is now preventing the network ID to be zero, thus Olympic support is dropped. Make sure to chose positive non-zero network IDs in future.
• Multithreaded snapshot creation (#9239): adds a CLI argument --snapshot-threads which specifies the number of threads. This helps improving the performance of full nodes that wish to provide warp-snapshots for the network. The gain in performance comes with a slight drawback in increased snapshot size.
• Expose config max-round-blocks-to-import (#9439): Parity Ethereum imports blocks in rounds. If at the end of any round, the queue is not empty, we consider it to be importing and won't notify pubsub. On large re-orgs (10+ blocks), this is possible. The default max_round_blocks_to_import is increased to 12 and configurable via the --max-round-blocks-to-import CLI flag. With unstable network conditions, it is advised to increase the number. This shouldn't have any noticeable performance impact unless the number is set to really large.
• Increase Gas-floor-target and Gas Cap (#9564): the default values for gas floor target are 8_000_000 and gas cap 10_000_000, similar to Geth 1.8.15+.
• Produce portable binaries (#9725): we now produce portable binaries, but it may incur some performance degradation. For ultimate performance it's now better to compile Parity Ethereum from source with PORTABLE=OFF environment variable.
• RPC: parity_allTransactionHashes (#9745): Get all pending transactions from the queue with the high performant parity_allTransactionHashes RPC method.
• Support eth_chainId RPC method (#9783): implements EIP-695 to get the chainID via RPC.
• AuRa: finalize blocks (#9692): The AuRa engine was updated to emit ancestry actions to finalize blocks. The full client stores block finality in the database, the engine builds finality from an ancestry of ExtendedHeader; is_epoch_end was updated to take a vec of recently finalized headers; is_epoch_end_light was added which maintains the previous interface and is used by the light client since the client itself doesn't track finality.
