## Parity [v1.10.2](https://github.com/paritytech/parity/releases/tag/v1.10.2) (2018-04-24) ## Parity [v1.11.0](https://github.com/paritytech/parity/releases/tag/v1.10.0) (2018-05-09)
Parity 1.10.2 is a bug-fix release to improve performance and stability. This is the Parity 1.11.0-beta release! Hurray!
Notable changes in reversed alphabetical order:
- TOOLING: **Whisper CLI** [#8201](https://github.com/paritytech/parity/pull/8201)
- `whisper-cli` is a standalone tool to communicate with the Whisper protocol.
- It provides functionality to specify `whisper-pool-size`, `port` and `address` to use.
- All whisper RPC APIs are enabled and can be directly acessed.
I'm not used to writing these changelogs but I guess that would explain it
- JSON-RPC API: **Return error in case eth_call returns VM errors** [#8448](https://github.com/paritytech/parity/pull/8448)
- This changes the behaviors of `eth_call` to respect VM errors if any.
- In case of `REVERT`, it will also return the reverted return data in hex format.
- ENGINES: **Block reward contract** [#8419](https://github.com/paritytech/parity/pull/8419)
- The _AuRa_ PoA engine has now support for having a contract to calculate the block rewards.
- The engine passes a list of benefactors and reward types to the contract which then returns a list of addresses and respective rewards.
- CORE: **Private transactions integration pr** [#6422](https://github.com/paritytech/parity/pull/6422)
- Parity now provides a private transactions system.
- Please, check out our wiki to get and [overview and setup instructions](https://wiki.parity.io/Private-Transactions.html).
- CORE: **New Transaction Queue implementation** [#8074](https://github.com/paritytech/parity/pull/8074)
- Verification is now done in parallel.
- Previous queue had `O(1)` time to get pending set, but `O(n^2)` insertion time. And obviously insertion/removal happens much more often than retrieving the pending set (only for propagation and pending block building) Currently we have `O(n * log(senders))` pending set time (with cache) and `O(tx_per_sender)` (usually within `log(tx_per_sender)`) insertion time.
- `Scoring` and `Readiness` are separated from the pool, so it's easier to customize them or introduce different definitions (for instance for [EIP-859](https://github.com/ethereum/EIPs/issues/859) or private transactions, etc).
- Banning removed, soft-penalization introduced instead: if transaction exceeds the limit other transactions from that sender get lower priority.
- There is no explicit distinction between current and future transactions in the pool - `Readiness` determines that. Because of this we additionally remove `future` transactions that occupy the pool for long time.
- CONFIGURATION: **Warp-only sync with --warp-barrier [block-number] flag.** [#8228](https://github.com/paritytech/parity/pull/8228)
- Enables warp-only sync in case `--warp-barrier [block-number]` is provided.
- This avoids clients to warp to outdated snapshots that are too far away from the best block.
- This avoids clients to fall back to normal sync if there are no recent snapshots available currently.
- CONFIGURATION: **Disable UI by default.** [#8105](https://github.com/paritytech/parity/pull/8105)
- The user interface is now disabled by default. It still can be activated with the `--force-ui` flag.
- To get the stand-alone Parity UI, please check the dedicated [releases page](https://github.com/parity-js/shell/releases).
- CONFIGURATION: **Auto-updater improvements** [#8078](https://github.com/paritytech/parity/pull/8078)
- Added `--auto-update-delay` to randomly delay updates by `n` blocks. This takes into account the number of the block of the update release (old updates aren't delayed).
- Added `--auto-update-check-frequency` to define the periodicity of auto-update checks in number of blocks.
- This is an important improvement to ensure the network does not update all clients at the same time.
- CHAIN SPECS: **Enable WebAssembly and Byzantium for Ellaism** [#8520](https://github.com/paritytech/parity/pull/8520)
- This activates the Ellaism Byzantium hardfork ([2018-0004-byzantium](https://github.com/ellaism/specs/blob/master/specs/2018-0004-byzantium.md)) at block `2_000_000`.
- This enables the Wasm VM on Ellaism ([2018-0003-wasm-hardfork](https://github.com/ellaism/specs/blob/master/specs/2018-0003-wasm-hardfork.md)) at block `2_000_000`.
- Please, upgrade your clients if you run an Ellaism configuration.
- CHAIN SPECS: **Dev chain - increase gasLimit to 8_000_000** [#8362](https://github.com/paritytech/parity/pull/8362)
- This increases the default block gas limit on development chains to `8_000_000`.
- Please note, this makes previous dev chain configurations incompatible.
- CHAIN SPECS: **Add MCIP-6 Byzyantium transition to Musicoin spec** [#7841](https://github.com/paritytech/parity/pull/7841)
- This activates the Musicoin Byzantium hardfork ([MCIP-6](https://github.com/Musicoin/MCIPs/blob/master/MCIPS/mcip-6.md)) at block `2_222_222`.
- Please, upgrade your clients if you run a Musicoin configuration.

The **Parity Wallet (a.k.a. "UI") is now disabled by default**. We are preparing to split the wallet from the core client. - Some tiny modifications. ([#8163](https://github.com/paritytech/parity/pull/8163))
- Secretstore: store key author address in db ([#7887](https://github.com/paritytech/parity/pull/7887))
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). - Rename DatabaseValueView::new to from_rlp ([#8159](https://github.com/paritytech/parity/pull/8159))
- Dapps: update parity-ui dependencies ([#8160](https://github.com/paritytech/parity/pull/8160))

### 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).

### 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 [v1.10.0](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`.
