+## Parity [v1.6.10](https://github.com/paritytech/parity/releases/tag/v1.6.10) (2017-07-23)
+
+This is a hotfix release for the stable channel addressing the recent [multi-signature wallet vulnerability](https://blog.parity.io/security-alert-high-2/). Note, upgrading is not mandatory, and all future multi-sig wallets created by any version of Parity are secure.
+
+All Changes:
+
+- Backports for stable [#6116](https://github.com/paritytech/parity/pull/6116)
+  - Remove chunk to restore from pending set only upon successful import [#6112](https://github.com/paritytech/parity/pull/6112)
+  - Blacklist bad snapshot manifest hashes upon failure [#5874](https://github.com/paritytech/parity/pull/5874)
+  - Bump snap version and tweak importing detection logic [#6079](https://github.com/paritytech/parity/pull/6079) (modified to work)
+- Fix docker build for stable [#6118](https://github.com/paritytech/parity/pull/6118)
+- Backported wallet fix [#6104](https://github.com/paritytech/parity/pull/6104)
+  - Fix initialisation bug. ([#6102](https://github.com/paritytech/parity/pull/6102))
+  - Update wallet library modifiers ([#6103](https://github.com/paritytech/parity/pull/6103))
+- Bump to v1.6.10
+
+## Parity [v1.7.0](https://github.com/paritytech/parity/releases/tag/v1.7.0) (2017-07-23)
+
+Parity 1.7.0 is a major release introducing several important features:
+
+- **Experimental [Light client](https://github.com/paritytech/parity/wiki/The-Parity-Light-Protocol-(PIP)) support**. Start Parity with `--light` to enable light mode.
+- **Experimental web wallet**. A hosted version of Parity that keeps the keys and signs transactions using your browser storage. Try it at https://wallet.parity.io or run your own with `--public-node`.
+- **WASM contract support**. Private networks can run contracts compiled into WASM bytecode. _More information and documentation to follow_.
+- **DApps and RPC server merge**. DApp and RPC are now available through a single API endpoint. DApp server related settings are deprecated.
+- **Export accounts from the wallet**. Backing up your keys can now simply be managed through the wallet interface.
+- **PoA/Kovan validator set contract**. The PoA network validator-set management via smart contract is now supported by warp and light sync.
+- **PubSub API**. https://github.com/paritytech/parity/wiki/JSONRPC-Parity-Pub-Sub-module
+- **Signer apps for IOS and Android**.
+
