## Parity [v1.10.0](https://github.com/paritytech/parity/releases/tag/v1.10.0) (2018-03-22)

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: Parity Wallet](https://wiki.parity.io/Parity-Wallet)
- [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 VM Design](https://wiki.parity.io/WebAssembly-Design)
- [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`.
