 If you would like to contribute to Parity Ethereum, please **fork it**, fix bugs or implement features, and [propose a pull request](https://github.com/paritytech/parity-ethereum/compare).
 
-Please, refer to the [Coding Guide](https://wiki.parity.io/Coding-guide) in our wiki for more details about hacking on Parity.
+### Labels & Milestones
+
+We use [labels](https://github.com/paritytech/parity-ethereum/labels) to manage PRs and issues and communicate the state of a PR. Please familiarize yourself with them. Furthermore we are organizing issues in [milestones](https://github.com/paritytech/parity-ethereum/milestones). Best way to get started is to a pick a ticket from the current milestone tagged [`easy`](https://github.com/paritytech/parity-ethereum/labels/Q2-easy%20%F0%9F%92%83) and get going, or [`mentor`](https://github.com/paritytech/parity-ethereum/labels/Q1-mentor%20%F0%9F%95%BA) and get in contact with the mentor offering their support on that larger task.
+
+### Rules
+
+There are a few basic ground-rules for contributors (including the maintainer(s) of the project):
+
+* **No pushing directly to the master branch**.
+* **All modifications** must be made in a **pull-request** to solicit feedback from other contributors.
+* Pull-requests cannot be merged before CI runs green and two reviewers have given their approval.
+* Contributors should adhere to the [Parity Ethereum Style Guide](https://wiki.parity.io/Parity-Ethereum-Style-Guide).
+
+### Recommendations
+
+* **Non-master branch names** *should* be prefixed with a short name moniker, followed by the associated Github Issue ID (if any), and a brief description of the task using the format `<GITHUB_USERNAME>-<ISSUE_ID>-<BRIEF_DESCRIPTION>` (e.g. `gavin-123-readme`). The name moniker helps people to inquiry about their unfinished work, and the GitHub Issue ID helps your future self and other developers (particularly those who are onboarding) find out about and understand the original scope of the task, and where it fits into Parity Ethereum [Projects](https://github.com/paritytech/parity-ethereum/projects).
+* **Remove stale branches periodically**
+
+### Preparing Pull Requests
+
+* If your PR does not alter any logic (e.g. comments, dependencies, docs), then it may be tagged [`insubstantial`](https://github.com/paritytech/parity-ethereum/pulls?q=is%3Aopen+is%3Apr+label%3A%22A2-insubstantial+%F0%9F%91%B6%22).
+
+* Once a PR is ready for review please add the [`pleasereview`](https://github.com/paritytech/parity-ethereum/pulls?utf8=%E2%9C%93&q=is%3Aopen+is%3Apr+label%3A%22A0-pleasereview+%F0%9F%A4%93%22+) label.
+
+### Reviewing Pull Requests*:
+
+* At least two reviewers are required to review PRs (even for PRs tagged [`insubstantial`](https://github.com/paritytech/parity-ethereum/pulls?q=is%3Aopen+is%3Apr+label%3A%22A2-insubstantial+%F0%9F%91%B6%22)).
+
+When doing a review, make sure to look for any:
+
+* Buggy behavior.
+* Undue maintenance burden.
+* Breaking with house coding style.
+* Pessimization (i.e. reduction of speed as measured in the projects benchmarks).
+* Breaking changes should be carefuly reviewed and tagged as such so they end up in the [changelog](../CHANGELOG.md).
+* Uselessness (i.e. it does not strictly add a feature or fix a known issue).

+## Parity-Ethereum [v2.6.0](https://github.com/paritytech/parity-ethereum/releases/tag/v2.6.0)
 
-## Parity-Ethereum [v2.0.0](https://github.com/paritytech/parity-ethereum/releases/tag/v2.0.0) "Ethereum" (2018-07-18)
+Parity-Ethereum 2.6.0-beta is a minor release that stabilizes the 2.6 branch by
+marking it as a beta release.
 
-This is the Parity-Ethereum//v2.0.0-beta release, code-named "Ethereum", **YOLO!**
+This release includes:
+  * Major refactoring of the codebase
+  * Many bugfixes
+  * Significant improvements to logging, error and warning message clarity.
+  * SecretStore: remove support of old database formats (#10757)
+      * This is a potentially breaking change if you have not upgraded for
+          quite some time.
 
-Please note, Parity-Ethereum//v2.0.0 comes with some breaking changes that might be interrupting your usual workflows. Please mind them before upgrading:
-
-- The Parity client is now called _Parity-Ethereum_ to distinguish it from other software we provide, such as [_Parity-Bitcoin_](https://github.com/paritytech/parity-bitcoin/) and [_Parity-Polkadot_](https://github.com/paritytech/polkadot) ([#9052](https://github.com/paritytech/parity-ethereum/pull/9052)).
-- The public node and the user interface (a.k.a. _"Parity Wallet"_) are completely removed from the Parity-Ethereum//v2.0.0 client ([#8758](https://github.com/paritytech/parity-ethereum/pull/8758), [#8783](https://github.com/paritytech/parity-ethereum/pull/8783), [#8641](https://github.com/paritytech/parity-ethereum/pull/8641)). Users interested running a Parity Wallet, check out [the stand-alone UI application](https://github.com/Parity-JS/shell/releases).
-- The DApps subsystem was completely removed from the client ([#9017](https://github.com/paritytech/parity-ethereum/pull/9017), [#9107](https://github.com/paritytech/parity-ethereum/pull/9107)). Again, use the standalone wallet if you wish to continue working with them.
-- Windows and MacOS versions are not available as installer anymore and the system trays were removed ([#8778](https://github.com/paritytech/parity-ethereum/pull/8778)). If you desire to run Parity-Ethereum on Windows or MacOS, you still can get the binaries from our mirrors. Furthermore, MacOS users are encouraged [to use our homebrew tap](https://github.com/paritytech/homebrew-paritytech/).
-- Linux versions are not available as deb-/rpm-packages anymore ([#8887](https://github.com/paritytech/parity-ethereum/pull/8887)). Communities are encouraged to provide their own packages or maintain their own repositories, such as [Arch Linux does](https://www.archlinux.org/packages/community/x86_64/parity/) for instance.
-- MD5-checksums are completely replaced by SHA256-checksums ([#8884](https://github.com/paritytech/parity-ethereum/pull/8884)). This is also reflected on our homepage by now.
-- Deprecated, removed, or replaced CLI-options are hidden from client `--help` to further discourage their usage ([#8967](https://github.com/paritytech/parity-ethereum/pull/8967)).
-
-Additional noteworthy changes to the client:
-
-- Tracing of precompiled contracts when the transfer value is not zero ([#8486](https://github.com/paritytech/parity-ethereum/pull/8486))
-- _Parity-Ethereum_ as a library now provides APIs for running full and light nodes and a C interface ([#8412](https://github.com/paritytech/parity-ethereum/pull/8412)). Shared crates are now available in [_Parity-Common_](https://github.com/paritytech/parity-common) ([#9083](https://github.com/paritytech/parity-ethereum/pull/9083)).
-- The Morden database and keys are now moved to a `./Morden` subdirectory instead of `./test` which is by default used by Ropsten ([#8621](https://github.com/paritytech/parity-ethereum/pull/8621)).
-- Adding support for having an on-chain contract calculating the block rewards ([#8419](https://github.com/paritytech/parity-ethereum/pull/8419)).
-- Enforcing warp-only synchronization with `--warp-barrier [blocknumber]` flag ([#8228](https://github.com/paritytech/parity-ethereum/pull/8228)).
-- Adding a fork-choice and meta-data framework suitable for implementing Casper ([#8401](https://github.com/paritytech/parity-ethereum/pull/8401)).
-- Returning an error if RLP-size of a transaction exceeds a 300kB limit ([#8473](https://github.com/paritytech/parity-ethereum/pull/8473)).
-- Warp-sync is now resumable by keeping the downloaded chunks between client restarts. Also, it seeds downloaded snapshots for other nodes ([#8544](https://github.com/paritytech/parity-ethereum/pull/8544)).
-- The developer chain `--chain dev` now contains Byzantium features, this breaks existing developer chains ([#8717](https://github.com/paritytech/parity-ethereum/pull/8717)).
-- The EIP150, EIP160 and EIP161 forks are now to be specified in common params section of a chain-spec file instead of the Ethash params to enable these features on non-proof-of-work chains ([#8614](https://github.com/paritytech/parity-ethereum/pull/8614)). Please update your chain specs.
-- Allowing to disable local-by-default for transactions with new configurations ([#8882](https://github.com/paritytech/parity-ethereum/pull/8882)).
-- Never drop local transactions from different senders ([#9002](https://github.com/paritytech/parity-ethereum/pull/9002)).
-- Optimize pending transactions filter and fix ethstats reporting of pending transactions ([#9026](https://github.com/paritytech/parity-ethereum/pull/9026)).
-- Add separate database directory for light client allowing to run full and light nodes at the same time ([#9064](https://github.com/paritytech/parity-ethereum/pull/9064)).
-
-If you are upgrading directly from versions 1.10.9 or earlier, please note important changes to our transaction-queue implementation, namely:
-
-- The pool now limits transactions per-sender (see `--tx-queue-per-sender`), local transactions also have to obey that limit. Consider increasing the limit via CLI-flag when running benchmarks or sending a lot of transactions at once.
-- In case the pool is full, transactions received over the network, but originating from accounts that you have private keys for might not get accepted to the pool any more with higher priority. Consider running with larger pool size or submitting the transactions directly on the node via `eth_sendRawTransaction`.
+ As of today, Parity-Ethereum 2.4 reaches end of life, and everyone is
+ encouraged to upgrade.

+  - Parity-version: bump stable to 1.11.9
+  - Fix compilation error on nightly rust ([#8707](https://github.com/paritytech/parity-ethereum/pull/8707))
+    - On nightly rust passing `public_url` works but that breaks on stable. This works for both.
+  - Parity-version: bump stable to 1.11.10

+    - Check if synced when using eth_getWork ([#9193](https://github.com/paritytech/parity-ethereum/issues/9193))
+    - Don't use fn syncing
+    - Fix identation
+    - Fix typo
+    - Don't check for warping
+    - Rpc: avoid calling queue_info twice on eth_getWork
+  - Fix potential as_usize overflow when casting from U256 in miner ([#9221](https://github.com/paritytech/parity-ethereum/pull/9221))
+  - Allow old blocks from peers with lower difficulty ([#9226](https://github.com/paritytech/parity-ethereum/pull/9226))
+    - Previously we only allow downloading of old blocks if the peer difficulty was greater than our syncing difficulty. This change allows downloading of blocks from peers where the difficulty is greater then the last downloaded old block.
+  - Update Dockerfile ([#9242](https://github.com/paritytech/parity-ethereum/pull/9242))
+    - Update Dockerfile

+  - Light client `Provide default nonce in transactions when it´s missing` ([#9370](https://github.com/paritytech/parity-ethereum/pull/9370))
+    - Provide `default_nonce` in tx`s when it´s missing
+    - When `nonce` is missing in a `EthTransaction` will cause it to fall in these cases provide `default_nonce` value instead!
+  - Changed http:// to https:// on Yasm link ([#9369](https://github.com/paritytech/parity-ethereum/pull/9369))

+    - Provide `default_nonce` in tx`s when it´s missing

+    - Address grumbles
+  - Ethcore: kovan: delay activation of strict score validation ([#9406](https://github.com/paritytech/parity-ethereum/pull/9406))

+  - Better support for eth_getLogs in light mode ([#9186](https://github.com/paritytech/parity-ethereum/pull/9186))
+    - Light client on-demand request for headers range.
+    - Cache headers in HeaderWithAncestors response.
+      - Also fulfills request locally if all headers are in cache.
+    - Lightfetch::logs fetches missing headers on demand.
+    - Lightfetch::logs limit the number of headers requested at a time.
+    - Lightfetch::logs refactor header fetching logic.
+    - Enforce limit on header range length in light client logs request.
+    - Fix light request tests after struct change.
+    - Respond to review comments.
+  - Propagate transactions for next 4 blocks. ([#9265](https://github.com/paritytech/parity-ethereum/pull/9265))
+    - This PR also removes the limit of max 64 transactions per packet, currently we only attempt to prevent the packet size to go over 8MB. This will only be the case for super-large transactions or high-block-gas-limit chains.
+    - Patching this is important only for chains that have blocks that can fit more than 4k transactions (over 86M block gas limit)
+    - For mainnet, we should actually see a tiny bit faster propagation since instead of computing 4k pending set, we only need `4 * 8M / 21k = 1523` transactions.

 Parity 1.11.7 "Prosperity" is a bug-fix release to improve performance and stability that marks the 1.11 release track as `stable`. Among other fixes, this release significantly addresses peering and synchronization issues. If you experienced such issues before, upgrading is highly recommended. If you rely on old versions of Parity, check out the `old-stable-1.10` branch, cherry-pick fixes, and compile your binaries independently. There will be no official support for any versions prior to 1.11.7, however (EOL).

+
+Parity-Ethereum 2.0.3-beta is a bug-fix release to improve performance and stability. Hopefully. ;)
+

+    - Update Dockerfile

+    - Closes [#9255](https://github.com/paritytech/parity-ethereum/issues/9255)
+    - This PR also removes the limit of max 64 transactions per packet, currently we only attempt to prevent the packet size to go over 8MB. This will only be the case for super-large transactions or high-block-gas-limit chains.
+    - Patching this is important only for chains that have blocks that can fit more than 4k transactions (over 86M block gas limit)
+    - For mainnet, we should actually see a tiny bit faster propagation since instead of computing 4k pending set, we only need `4 * 8M / 21k = 1523` transactions.

+## Parity-Ethereum [v2.0.0](https://github.com/paritytech/parity-ethereum/releases/tag/v2.0.0) "Ethereum" (2018-07-18)
+
+This is the Parity-Ethereum//v2.0.0-beta release, code-named "Ethereum", **YOLO!**
+
+Please note, Parity-Ethereum//v2.0.0 comes with some breaking changes that might be interrupting your usual workflows. Please mind them before upgrading:
+
+- The Parity client is now called _Parity-Ethereum_ to distinguish it from other software we provide, such as [_Parity-Bitcoin_](https://github.com/paritytech/parity-bitcoin/) and [_Parity-Polkadot_](https://github.com/paritytech/polkadot) ([#9052](https://github.com/paritytech/parity-ethereum/pull/9052)).
+- The public node and the user interface (a.k.a. _"Parity Wallet"_) are completely removed from the Parity-Ethereum//v2.0.0 client ([#8758](https://github.com/paritytech/parity-ethereum/pull/8758), [#8783](https://github.com/paritytech/parity-ethereum/pull/8783), [#8641](https://github.com/paritytech/parity-ethereum/pull/8641)). Users interested running a Parity Wallet, check out [the stand-alone UI application](https://github.com/Parity-JS/shell/releases).
+- The DApps subsystem was completely removed from the client ([#9017](https://github.com/paritytech/parity-ethereum/pull/9017), [#9107](https://github.com/paritytech/parity-ethereum/pull/9107)). Again, use the standalone wallet if you wish to continue working with them.
+- Windows and MacOS versions are not available as installer anymore and the system trays were removed ([#8778](https://github.com/paritytech/parity-ethereum/pull/8778)). If you desire to run Parity-Ethereum on Windows or MacOS, you still can get the binaries from our mirrors. Furthermore, MacOS users are encouraged [to use our homebrew tap](https://github.com/paritytech/homebrew-paritytech/).
+- Linux versions are not available as deb-/rpm-packages anymore ([#8887](https://github.com/paritytech/parity-ethereum/pull/8887)). Communities are encouraged to provide their own packages or maintain their own repositories, such as [Arch Linux does](https://www.archlinux.org/packages/community/x86_64/parity/) for instance.
+- MD5-checksums are completely replaced by SHA256-checksums ([#8884](https://github.com/paritytech/parity-ethereum/pull/8884)). This is also reflected on our homepage by now.
+- Deprecated, removed, or replaced CLI-options are hidden from client `--help` to further discourage their usage ([#8967](https://github.com/paritytech/parity-ethereum/pull/8967)).
+
+Additional noteworthy changes to the client:
+
+- Tracing of precompiled contracts when the transfer value is not zero ([#8486](https://github.com/paritytech/parity-ethereum/pull/8486))
+- _Parity-Ethereum_ as a library now provides APIs for running full and light nodes and a C interface ([#8412](https://github.com/paritytech/parity-ethereum/pull/8412)). Shared crates are now available in [_Parity-Common_](https://github.com/paritytech/parity-common) ([#9083](https://github.com/paritytech/parity-ethereum/pull/9083)).
+- The Morden database and keys are now moved to a `./Morden` subdirectory instead of `./test` which is by default used by Ropsten ([#8621](https://github.com/paritytech/parity-ethereum/pull/8621)).
+- Adding support for having an on-chain contract calculating the block rewards ([#8419](https://github.com/paritytech/parity-ethereum/pull/8419)).
+- Enforcing warp-only synchronization with `--warp-barrier [blocknumber]` flag ([#8228](https://github.com/paritytech/parity-ethereum/pull/8228)).
+- Adding a fork-choice and meta-data framework suitable for implementing Casper ([#8401](https://github.com/paritytech/parity-ethereum/pull/8401)).
+- Returning an error if RLP-size of a transaction exceeds a 300kB limit ([#8473](https://github.com/paritytech/parity-ethereum/pull/8473)).
+- Warp-sync is now resumable by keeping the downloaded chunks between client restarts. Also, it seeds downloaded snapshots for other nodes ([#8544](https://github.com/paritytech/parity-ethereum/pull/8544)).
+- The developer chain `--chain dev` now contains Byzantium features, this breaks existing developer chains ([#8717](https://github.com/paritytech/parity-ethereum/pull/8717)).
+- The EIP150, EIP160 and EIP161 forks are now to be specified in common params section of a chain-spec file instead of the Ethash params to enable these features on non-proof-of-work chains ([#8614](https://github.com/paritytech/parity-ethereum/pull/8614)). Please update your chain specs.
+- Allowing to disable local-by-default for transactions with new configurations ([#8882](https://github.com/paritytech/parity-ethereum/pull/8882)).
+- Never drop local transactions from different senders ([#9002](https://github.com/paritytech/parity-ethereum/pull/9002)).
+- Optimize pending transactions filter and fix ethstats reporting of pending transactions ([#9026](https://github.com/paritytech/parity-ethereum/pull/9026)).
+- Add separate database directory for light client allowing to run full and light nodes at the same time ([#9064](https://github.com/paritytech/parity-ethereum/pull/9064)).
+
+If you are upgrading directly from versions 1.10.9 or earlier, please note important changes to our transaction-queue implementation, namely:
+
+- The pool now limits transactions per-sender (see `--tx-queue-per-sender`), local transactions also have to obey that limit. Consider increasing the limit via CLI-flag when running benchmarks or sending a lot of transactions at once.
+- In case the pool is full, transactions received over the network, but originating from accounts that you have private keys for might not get accepted to the pool any more with higher priority. Consider running with larger pool size or submitting the transactions directly on the node via `eth_sendRawTransaction`.

+## Parity-Ethereum [v2.2.5](https://github.com/paritytech/parity-ethereum/releases/tag/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 with`empty_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 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 set`strict_empty_steps_transition` to `0xfffffffff` to disable it.
+
+The full list of included changes:
+- Backports for beta 2.2.5 ([#10047](https://github.com/paritytech/parity-ethereum/pull/10047))
+	- Bump beta to 2.2.5 ([#10047](https://github.com/paritytech/parity-ethereum/pull/10047))
+	- Fix empty steps ([#9939](https://github.com/paritytech/parity-ethereum/pull/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](https://github.com/paritytech/parity-ethereum/pull/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](https://github.com/paritytech/parity-ethereum/pull/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](https://github.com/paritytech/parity-ethereum/pull/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](https://github.com/paritytech/parity-ethereum/pull/10024))
+	- Fix: test corpus_inaccessible panic ([#10019](https://github.com/paritytech/parity-ethereum/pull/10019))
+
+## Parity-Ethereum [v2.2.2](https://github.com/paritytech/parity-ethereum/releases/tag/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`.

+## 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.
+

+## Parity-Ethereum [v2.3.0](https://github.com/paritytech/parity-ethereum/releases/tag/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](https://github.com/paritytech/parity-ethereum/pull/10189))
+  - Read more: [Security Alert: Ethereum Constantinople Postponement](https://blog.ethereum.org/2019/01/15/security-alert-ethereum-constantinople-postponement/)
+- **Networking** - All networks: Ping nodes from discovery ([#10167](https://github.com/paritytech/parity-ethereum/pull/10167))
+- **Wasm** - Kovan Network: Update pwasm-utils to 0.6.1 ([#10134](https://github.com/paritytech/parity-ethereum/pull/10134))
+
+Other notable changes:
+
+- Existing blocks in the database are now kept when restoring a Snapshot. ([#8643](https://github.com/paritytech/parity-ethereum/pull/8643))
+- Block and transaction propagation is improved significantly. ([#9954](https://github.com/paritytech/parity-ethereum/pull/9954))
+- The ERC-191 Signed Data Standard is now supported by `personal_sign191`. ([#9701](https://github.com/paritytech/parity-ethereum/pull/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](https://github.com/paritytech/parity-ethereum/pull/9631))
+- Add support for ERC-1186 `eth_getProof` ([#9001](https://github.com/paritytech/parity-ethereum/pull/9001))
+- Add experimental RPCs flag to enable ERC-191, ERC-712, and ERC-1186 APIs via `--jsonrpc-experimental` ([#9928](https://github.com/paritytech/parity-ethereum/pull/9928))
+- Make `CALLCODE` to trace value to be the code address. ([#9881](https://github.com/paritytech/parity-ethereum/pull/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](https://github.com/paritytech/parity-ethereum/pull/9955))
+- Also, unknown fields in chain specs are now rejected. ([#9972](https://github.com/paritytech/parity-ethereum/pull/9972))
+- The Tendermint engine was removed from Parity Ethereum and is no longer available and maintained. ([#9980](https://github.com/paritytech/parity-ethereum/pull/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](https://github.com/paritytech/parity-ethereum/pull/10123))
+- Strict empty steps validation ([#10041](https://github.com/paritytech/parity-ethereum/pull/10041))
+  - If you have a chain with`empty_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 set`strict_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_.
