## Parity [v1.10.0](https://github.com/paritytech/parity/releases/tag/v1.10.0) (2018-03-22)
2018-03-01 20:53:21 +01:00
2018-03-23 10:53:26 +01:00
This is the Parity 1.10.0-beta release! Cool!

### Disabling the Parity Wallet
2018-02-20 17:28:09 +01:00
2018-03-23 10:53:26 +01:00
The **Parity Wallet (a.k.a. "UI") is now disabled by default** . We are preparing to split the wallet from the core client.
2018-02-20 17:28:09 +01:00
2018-03-23 10:53:26 +01:00
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 ).

### Introducing the Wasm VM
2018-02-05 10:34:21 +01:00
2018-03-23 10:53:26 +01:00
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` .
2018-02-01 13:50:23 +01:00
2018-03-23 10:53:26 +01:00
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 ).

### Empty step messages in PoA
2018-02-01 13:50:23 +01:00
2018-03-23 10:53:26 +01:00
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.
2018-01-10 00:11:13 +01:00
2018-03-23 10:53:26 +01:00
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
2018-01-10 00:11:13 +01:00
2018-03-23 10:53:26 +01:00
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` .
2018-01-10 00:11:13 +01:00
2018-03-23 10:53:26 +01:00
We fixed DELEGATECALL `from` and `to` fields, see [#7166 ](https://github.com/paritytech/parity/issues/7166 ).
2018-01-10 00:11:13 +01:00
2018-03-23 10:53:26 +01:00
We reduced the default USD per transaction value to 0.0001. Thanks, @MysticRyuujin !
2017-12-12 15:37:10 +01:00
2018-03-23 10:53:26 +01:00
The Musicoin chain is now enabled with Byzantium features starting at block `2_222_222` .
