 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 [v2.2.5](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.
+## Parity-Ethereum [v2.5.6](https://github.com/paritytech/parity-ethereum/releases/tag/v2.5.5)
 
-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 v2.5.6-stable is a bugfix release that improves stability.
 
-## 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`.
+* Allow specifying hostnames for node URLs
+* Fix a bug where archive nodes were losing peers

-## Parity-Ethereum [v2.2.1](https://github.com/paritytech/parity-ethereum/releases/tag/v2.2.1) (2018-11-15)
+## Parity-Ethereum [v2.5.5](https://github.com/paritytech/parity-ethereum/releases/tag/v2.5.5)
 
-Parity-Ethereum 2.2.1-beta is the first v2.2 release, and might introduce features that break previous work flows, among others:
+Parity-Ethereum v2.5.5-stable is a minor release that improves performance and stability.
+This release stabilises the 2.5 branch.
 
-- 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.
+As of today, Parity-Ethereum 2.4 reaches end of life and everyone is
+encouraged to upgrade.

+Parity-Ethereum 2.1.10-stable 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.

+- Backports for beta 2.2.5 ([#10047](https://github.com/paritytech/parity-ethereum/pull/10047))

+
+## 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 [v2.3.2](https://github.com/paritytech/parity-ethereum/releases/tag/v2.3.2) (2019-02-03)
+
+Parity-Ethereum 2.3.2-stable is a security-relevant release. A bug in the JSONRPC-deserialization module can cause crashes of all versions of Parity Ethereum nodes if an attacker is able to submit a specially-crafted RPC to certain publicly available endpoints.

+
+## 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_.
