## Parity-Ethereum [v2.2.1](https://github.com/paritytech/parity-ethereum/releases/tag/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](https://github.com/paritytech/parity-ethereum/pull/9763)) and drop support for Olympic testnet ([#9801](https://github.com/paritytech/parity-ethereum/pull/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](https://github.com/paritytech/parity-ethereum/pull/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](https://github.com/paritytech/parity-ethereum/pull/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](https://github.com/paritytech/parity-ethereum/pull/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](https://github.com/paritytech/parity-ethereum/pull/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](https://github.com/paritytech/parity-ethereum/pull/9745)): Get all pending transactions from the queue with the high performant `parity_allTransactionHashes` RPC method.
- Support `eth_chainId` RPC method ([#9783](https://github.com/paritytech/parity-ethereum/pull/9783)): implements EIP-695 to get the chainID via RPC.
- AuRa: finalize blocks ([#9692](https://github.com/paritytech/parity-ethereum/pull/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.
