Release Parity 1.11.1-beta · openethereum/parity-ethereum

This is the Parity 1.11.1-beta release! Hurray!

Notable changes in reversed alphabetical order:

TOOLING: Whisper CLI #8201
- whisper-cli is a standalone tool to communicate with the Whisper protocol.
- It provides functionality to specify whisper-pool-size, port and address to use.
- All whisper RPC APIs are enabled and can be directly accessed.
JSON-RPC API: Return error in case eth_call returns VM errors #8448
- This changes the behaviors of eth_call to respect VM errors if any.
- In case of REVERT, it will also return the reverted return data in hex format.
ENGINES: Block Reward Contract #8419
- The AuRa PoA engine has now support for having a contract to calculate the block rewards.
- The engine passes a list of benefactors and reward types to the contract which then returns a list of addresses and respective rewards.
CORE: Private Transactions #6422
- Parity now provides a private transactions system.
- Please, check out our wiki to get an overview and setup instructions.
CORE: New Transaction Queue implementation #8074
- Verification is now done in parallel.
- The previous queue had O(1) time to get pending set, but O(n^2) insertion time. And obviously insertion/removal happens much more often than retrieving the pending set (only for propagation and pending block building) Currently we have O(n * log(senders)) pending set time (with cache) and O(tx_per_sender) (usually within log(tx_per_sender)) insertion time.
- Scoring and Readiness are separated from the pool, so it's easier to customize them or introduce different definitions (for instance for EIP-859 or private transactions, etc).
- Banning removed, soft-penalization introduced instead: if a transaction exceeds the limit other transactions from that sender get lower priority.
- There is no explicit distinction between current and future transactions in the pool - Readiness determines that. Because of this we additionally remove future transactions that occupy the pool for a long time.
CONFIGURATION: Warp-only sync with --warp-barrier [block-number] flag. #8228
- Enables warp-only sync in case --warp-barrier [block-number] is provided.
- This avoids clients to warp to outdated snapshots that are too far away from the best block.
- This avoids clients to fall back to normal sync if there are no recent snapshots available currently.
CONFIGURATION: Disable UI by default. #8105
- The user interface is now disabled by default. It still can be activated with the --force-ui flag.
- To get the stand-alone Parity UI, please check the dedicated releases page.
CONFIGURATION: Auto-updater improvements #8078
- Added --auto-update-delay to randomly delay updates by n blocks. This takes into account the number of the block of the update release (old updates aren't delayed).
- Added --auto-update-check-frequency to define the periodicity of auto-update checks in a number of blocks.
- This is an important improvement to ensure the network does not update all clients at the same time.
CHAIN SPECS: Enable WebAssembly and Byzantium for Ellaism #8520
- This activates the Ellaism Byzantium hardfork (2018-0004-byzantium) at block 2_000_000.
- This enables the Wasm VM on Ellaism (2018-0003-wasm-hardfork) at block 2_000_000.
- Please, upgrade your clients if you run an Ellaism configuration.
CHAIN SPECS: Dev chain - increase gasLimit to 8_000_000 #8362
- This increases the default block gas limit on development chains to 8_000_000.
- Please note, this makes previous dev chain configurations incompatible.
CHAIN SPECS: Add MCIP-6 Byzyantium transition to Musicoin spec #7841
- This activates the Musicoin Byzantium hardfork (MCIP-6) at block 2_222_222.
- Please, upgrade your clients if you run a Musicoin configuration.
