-## Parity [v1.8.5](https://github.com/paritytech/parity/releases/tag/v1.8.5) (2017-12-29)
+## Parity [v1.10.2](https://github.com/paritytech/parity/releases/tag/v1.10.2) (2018-04-24)
 
-Parity 1.8.5 changes the default behavior of JSON-RPC CORS setting, detects same-key engine signers in Aura networks, and updates bootnodes for the Kovan and Foundation networks.
-
-Note: The default value of `--jsonrpc-cors` option has been altered to disallow (potentially malicious) websites from accessing the low-sensitivity RPCs (viewing exposed accounts, proposing transactions for signing). Currently domains need to be whitelisted manually. To bring back previous behaviour run with `--jsonrpc-cors all` or `--jsonrpc-cors http://example.com`.
+Parity 1.10.2 is a bug-fix release to improve performance and stability.

+## Parity [v1.10.1](https://github.com/paritytech/parity/releases/tag/v1.10.1) (2018-04-17)
 
-Parity 1.8.4 applies fixes for Proof-of-Authority networks and schedules the Kovan-Byzantium hard-fork.
-
-- The Kovan testnet will fork on block `5067000` at `Thu Dec 14 2017 05:40:03 UTC`.
-  - This enables Byzantium features on Kovan.
-  - This disables uncles on Kovan for stability reasons.
-- Proof-of-Authority networks are advised to set `maximumUncleCount` to 0 in a future `maximumUncleCountTransition` for stability reasons.
-  - See the [Kovan chain spec](https://github.com/paritytech/parity/blob/master/ethcore/res/ethereum/kovan.json) for an example.
-  - New PoA networks created with Parity will have this feature enabled by default.
-
-Furthermore, this release includes the ECIP-1039 Monetary policy rounding specification for Ethereum Classic, reduces the maximum Ethash-block timestamp drift to 15 seconds, and fixes various bugs for WASM and the RPC APIs.
+Parity 1.10.1 is a bug-fix release to improve performance and stability. Among other changes, you can now use `--warp-barrier [BLOCK]` to specify a minimum block number to `--warp` to. This is useful in cases where clients restore to outdated snapshots far behind the latest chain head.

-## Parity [v1.8.3](https://github.com/paritytech/parity/releases/tag/v1.8.3) (2017-11-15)
+## Parity [v1.10.0](https://github.com/paritytech/parity/releases/tag/v1.10.0) (2018-03-22)
 
-Parity 1.8.3 contains several bug-fixes and removes the ability to deploy built-in multi-signature wallets.
+This is the Parity 1.10.0-beta release! Cool!
+
+### Disabling the Parity Wallet
+
+The **Parity Wallet (a.k.a. "UI") is now disabled by default**. We are preparing to split the wallet from the core client.
+
+To reactivate the parity wallet, you have to run Parity either with `parity --force-ui` (not recommended) or `parity ui` (deprecated) from the command line. Or, if you feel super fancy and want to test our pre-releases of the stand-alone electron wallet, head over to the [Parity-JS repositories and check the releases](https://github.com/Parity-JS/shell/releases).
+
+Further reading:

+- [Docs: How to customize Parity UI?](https://wiki.parity.io/FAQ-Customize-Parity-UI.html)
+- [Github: Parity-JS](https://github.com/parity-js)
+
+### Introducing the Wasm VM
+
+We are excited to announce support for **Wasm Smart Contracts on Kovan network**. The hard-fork to activate the Wasm-VM will take place on block `6_600_000`.
+
+To enable Wasm contracts on your custom network, just schedule a `wasmActivationTransition` at your favorite block number (e.g., `42`, `666`, or `0xbada55`). To hack your first Wasm smart contracts in Rust, have a look at the [Parity Wasm Tutorials](https://github.com/paritytech/pwasm-tutorial).

+- [Docs: Wasm tutorials and examples](https://wiki.parity.io/WebAssembly-Links)
+
+### Empty step messages in PoA
+
+To **reduce blockchain bloat, proof-of-authority networks can now enable _empty step messages_ which replace empty blocks**. Each step message will be signed and broadcasted by the issuing authorities, and included and rewarded in the next non-empty block.
+
+To enable empty step messages, set the `emptyStepsTransition` to your favorite block number. You can also specify a maximum number of empty steps with `maximumEmptySteps` in your chain spec.
+
+### Other noteworthy changes
+
+We removed the old database migrations from 2016. In case you upgrade Parity from a really, really old version, you will have to reset your database manually first with `parity <options> db kill`.
+
+We fixed  DELEGATECALL `from` and `to` fields, see [#7166](https://github.com/paritytech/parity/issues/7166).
+
+We reduced the default USD per transaction value to 0.0001. Thanks, @MysticRyuujin!
+
+The Musicoin chain is now enabled with Byzantium features starting at block `2_222_222`.

-## Parity [v1.8.2](https://github.com/paritytech/parity/releases/tag/v1.8.2) (2017-10-26)
+## Previous releases
 
-Parity 1.8.2 fixes an important potential consensus issue and a few additional minor issues:
-
-- `blockNumber` transaction field is now returned correctly in RPC calls.
-- Possible crash when `--force-sealing` option is used.

-## Parity [v1.8.1](https://github.com/paritytech/parity/releases/tag/v1.8.1) (2017-10-20)
-
-Parity 1.8.1 fixes several bugs with token balances, tweaks snapshot-sync, improves the performance of nodes with huge amounts of accounts and changes the Trezor account derivation path.
-
-**Important Note**: The **Trezor** account derivation path was changed in this release ([#6815](https://github.com/paritytech/parity/pull/6815)) to always use the first account (`m/44'/60'/0'/0/0` instead of `m/44'/60'/0'/0`). This way we enable compatibility with other Ethereum wallets supporting Trezor hardware-wallets. However, **action is required** before upgrading, if you have funds on your Parity Trezor wallet. If you already upgraded to 1.8.1, please downgrade to 1.8.0 first to recover the funds with the following steps:
-
-1. Make sure you have 1.8.0-beta and your Trezor plugged in.
-2. Create a new standard Parity account. Make sure you have backups of the recovery phrase and don't forget the password.
-3. Move your funds from the Trezor hardware-wallet account to the freshly generated Parity account.
-4. Upgrade to 1.8.1-beta and plug in your Trezor.
-5. Move your funds from your Parity account to the new Trezor account.
-6. Keep using Parity as normal.
-
-If you don't want to downgrade or move your funds off your Trezor-device, you can also use the official Trezor application or other wallets allowing to select the derivation path to access the funds.

 - create and manage your Ethereum accounts;
 - manage your Ether and any Ethereum tokens;
 - create and register your own tokens;
 - and much more.
 
+From Parity Ethereum client version >=1.10, the User Interface (UI) is accessible in a separate application called Parity UI.

 By default, Parity will also run a JSONRPC server on `127.0.0.1:8545` and a websockets server on `127.0.0.1:8546`. This is fully configurable and supports a number of APIs.

+## Parity [v1.8.6](https://github.com/paritytech/parity/releases/tag/v1.8.6) (2018-01-10)
+
+Parity 1.8.6 fixes a critical issue with the database eventually filling up user's disks. Upgrading is highly recommended as it will significantly improve your user experience. As a bonus, this release should enable users with slower hard-disk drives to catch up with the latest block again. Also, warp-sync performance was significantly improved. Please note, that the initial database compaction after upgrading might temporarily reduce the node's performance.
+
+In addition to our gas price histogram, this version now allows you to dynamically set the default gas price as percentile from the last 100 blocks (it defaults to median: `50`).
+
+    --gas-price-percentile=[PCT]        Set PCT percentile gas price value from
+                                        last 100 blocks as default gas price
+                                        when sending transactions.
+
+Last but not least, this release also fixes consensus issues with the Expanse chain enabling Byzantium. If you run Parity configured for Expanse, you might have to resync your chain after the upgrade.
+
+The full list of included changes:
+
+- RocksDB fix ([#7508](https://github.com/paritytech/parity/pull/7508))
+  - Kvdb: update rust-rocksdb version
+- Backports to beta ([#7434](https://github.com/paritytech/parity/pull/7434))

+
+## Parity [v1.8.5](https://github.com/paritytech/parity/releases/tag/v1.8.5) (2017-12-29)
+
+Parity 1.8.5 changes the default behavior of JSON-RPC CORS setting, detects same-key engine signers in Aura networks, and updates bootnodes for the Kovan and Foundation networks.
+
+Note: The default value of `--jsonrpc-cors` option has been altered to disallow (potentially malicious) websites from accessing the low-sensitivity RPCs (viewing exposed accounts, proposing transactions for signing). Currently domains need to be whitelisted manually. To bring back previous behaviour run with `--jsonrpc-cors all` or `--jsonrpc-cors http://example.com`.
+
+The full list of included changes:
+
+- Beta Backports ([#7297](https://github.com/paritytech/parity/pull/7297))

+## Parity [v1.8.4](https://github.com/paritytech/parity/releases/tag/v1.8.4) (2017-12-12)
+
+Parity 1.8.4 applies fixes for Proof-of-Authority networks and schedules the Kovan-Byzantium hard-fork.
+
+- The Kovan testnet will fork on block `5067000` at `Thu Dec 14 2017 05:40:03 UTC`.
+  - This enables Byzantium features on Kovan.
+  - This disables uncles on Kovan for stability reasons.
+- Proof-of-Authority networks are advised to set `maximumUncleCount` to 0 in a future `maximumUncleCountTransition` for stability reasons.
+  - See the [Kovan chain spec](https://github.com/paritytech/parity/blob/master/ethcore/res/ethereum/kovan.json) for an example.
+  - New PoA networks created with Parity will have this feature enabled by default.
+
+Furthermore, this release includes the ECIP-1039 Monetary policy rounding specification for Ethereum Classic, reduces the maximum Ethash-block timestamp drift to 15 seconds, and fixes various bugs for WASM and the RPC APIs.

+## Parity [v1.8.1](https://github.com/paritytech/parity/releases/tag/v1.8.1) (2017-10-20)
+
+Parity 1.8.1 fixes several bugs with token balances, tweaks snapshot-sync, improves the performance of nodes with huge amounts of accounts and changes the Trezor account derivation path.
+
+**Important Note**: The **Trezor** account derivation path was changed in this release ([#6815](https://github.com/paritytech/parity/pull/6815)) to always use the first account (`m/44'/60'/0'/0/0` instead of `m/44'/60'/0'/0`). This way we enable compatibility with other Ethereum wallets supporting Trezor hardware-wallets. However, **action is required** before upgrading, if you have funds on your Parity Trezor wallet. If you already upgraded to 1.8.1, please downgrade to 1.8.0 first to recover the funds with the following steps:
+
+1. Make sure you have 1.8.0-beta and your Trezor plugged in.
+2. Create a new standard Parity account. Make sure you have backups of the recovery phrase and don't forget the password.
+3. Move your funds from the Trezor hardware-wallet account to the freshly generated Parity account.
+4. Upgrade to 1.8.1-beta and plug in your Trezor.
+5. Move your funds from your Parity account to the new Trezor account.
+6. Keep using Parity as normal.
+
+If you don't want to downgrade or move your funds off your Trezor-device, you can also use the official Trezor application or other wallets allowing to select the derivation path to access the funds.
+
+The full list of included changes:
+
+- Add ECIP1017 to Morden config ([#6845](https://github.com/paritytech/parity/pull/6845))
+- Ethstore optimizations ([#6844](https://github.com/paritytech/parity/pull/6844))

+
+Parity 1.9.1 is a bug-fix release to improve performance and stability. It restores ERC-20 token balances, improves networking, fixes database corruptions on client shutdown, and fixes issues with the `--password` command-line flag. Happy syncing, fellow Ethereans!
+
+In addition, this stabilizes Kovan and other Proof-of-Authority networks. If you run a network with AuRa engine, updating is highly encouraged!

+
+## Parity [v1.9.0](https://github.com/paritytech/parity/releases/tag/v1.9.0) "Velocity" (2018-01-25)
+
+We are happy to announce our newest Parity 1.9 release. Among others, it enables the following features:
+
+- It integrates the fully reworked Parity Wallet and DApps browser (a.k.a. "UI 2.0", [#6819](https://github.com/paritytech/parity/pull/6819)).
+- It enables devp2p snappy compression ([#6683](https://github.com/paritytech/parity/pull/6683)).
+- AuRa Proof-of-Authority chains now disable uncles by default ([#7006](https://github.com/paritytech/parity/pull/7006)). Existing PoA chains can go through a "maximum uncle count transition" to achieve more stability ([#7196](https://github.com/paritytech/parity/pull/7196)).
+- Added Expanse's Byzantium hard-fork ([#7463](https://github.com/paritytech/parity/pull/7463)).
+- Added support for Ellaism chain ([#7222](https://github.com/paritytech/parity/pull/7222)).
+
+Further, users upgrading from 1.8 should acknowledge the following changes:
+
+- Fixed DELEGATECALL's from/to field ([#7568](https://github.com/paritytech/parity/pull/7568)).
+- Set zero nonce and gas price for calls by default ([#6954](https://github.com/paritytech/parity/pull/6954)).
+- Create pending blocks with all transactions from the queue ([#6942](https://github.com/paritytech/parity/pull/6942)).
+- Remove RPC parameter leniency now that Mist formats correctly ([#6651](https://github.com/paritytech/parity/pull/6651)). Parity stops accepting decimal-formatted block numbers and stops parsing the empty string as empty bytes.
+- Public nodes do not support the user interface anymore. If you are running a public node, please stay on the 1.8 branch of the stable releases.
+
+Additional noteworthy changes:
+
+- `ethstore` and `ethkey` have been significantly improved ([#6961](https://github.com/paritytech/parity/pull/6961)):
+  - `ethstore` now supports brute forcing pre-sale wallets given a password list for recovery.
+  - `ethkey` now supports multi-threaded generation of prefix-matching addresses.
+  - `ethkey` now supports prefix-matching brain wallets.
+  - `ethkey` now supports brain-wallets recovery-phrases lookup. This helps to find a correct phrase if you know the address you want to get yet you made a typo backing the phrase up, or forgot a word.
