-## 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 [v2.3.0](https://github.com/paritytech/parity-ethereum/releases/tag/v2.3.0) (2018-01-16)

-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 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.

-## Parity-Ethereum [v2.2.2](https://github.com/paritytech/parity-ethereum/releases/tag/v2.2.2) (2018-11-29)
+- **Consensus** - Ethereum Network: Pull Constantinople protocol upgrade on Ethereum (#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)
+- **Wasm** - Kovan Network: Update pwasm-utils to 0.6.1 (#10134)

-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.
+Other notable changes:

-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:
+- Existing blocks in the database are now kept when restoring a Snapshot. (#8643)
+- Block and transaction propagation is improved significantly. (#9954)
+- The ERC-191 Signed Data Standard is now supported by `personal_sign191`. (#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)
+- Add support for ERC-1186 `eth_getProof` (#9001)
+- Add experimental RPCs flag to enable ERC-191, ERC-712, and ERC-1186 APIs via `--jsonrpc-experimental` (#9928)
+- Make `CALLCODE` to trace value to be the code address. (#9881)

-```
-cargo build --release -p chainspec
-./target/release/chainspec /path/to/spec.json
-```
+Configuration changes:

-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`.
+- 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)
+- Also, unknown fields in chain specs are now rejected. (#9972)
+- The Tendermint engine was removed from Parity Ethereum and is no longer available and maintained. (#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)
+- Strict empty steps validation (#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_.

-## 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 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.

+## 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.
+
