Parity Ethereum 2.2.7-stable

Parity-Ethereum 2.2.7-stable 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)

Parity Ethereum 2.2.5-beta

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.

Upgrading is strongly recommended.

Parity Ethereum 2.2.2-beta "No Nick"

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.

Thanks for flying with Parity Ethereum!
