## Parity [v1.3.10](https://github.com/paritytech/parity/releases/tag/v1.3.10) (2016-11-04)

The latest 1.3 series release, now considered stable.

This includes several additional optimisations and fixes together with provisional support for the upcoming hard fork for EIP155/160/161.

- Stable branch reset to 1.3.10 [#3156](https://github.com/paritytech/parity/pull/3156)
- Backporting to beta [#3149](https://github.com/paritytech/parity/pull/3149)
- apply post-consolidation migrations after consolidating (BETA) [#3048](https://github.com/paritytech/parity/pull/3048)

- Backports for 1.3.10 [#2987](https://github.com/paritytech/parity/pull/2987)

## Parity [v1.3.9](https://github.com/paritytech/parity/releases/tag/v1.3.9) (2016-10-21)

This release enables EIP-150 hard fork for Ethereum Classic chain and resolves a few stability and performance issues, such as:
- Interrupted syncing on the test network.
- Block import delays caused by a large number of incoming transactions. A full re-sync is recommended for performance improvement to take effect.

Full changes:
- [beta] Resolve morden fork [#2776](https://github.com/paritytech/parity/pull/2776)
- Fixing botched merge [#2767](https://github.com/paritytech/parity/pull/2767)
- Backports for beta [#2764](https://github.com/paritytech/parity/pull/2764)

## Parity [v1.3.8](https://github.com/paritytech/parity/releases/tag/v1.3.8) (2016-10-15)

Parity 1.3.8 is our EIP150 hard-fork compliant release.

Running this will enact a mild change of the protocol at block number 2,463,000 which should occur on Tuesday 18th October 2016 at approximately 12:20 London time (BST). This change alters the gas prices for a number of operations, mainly centring around i/o intensive Merkle trie lookups (`BALANCE`, `EXTCODESIZE` &c.) and state-trie polluters (`SUICIDE`, `CREATE` and `CALL`). These operations were heavily underpriced, an oversight which lead to the recent degradation of network service. The full details of the alteration are specified in [EIP-150](https://github.com/ethereum/EIPs/issues/150).

Additionally several issues have been fixed including:
- a transaction queue limitation leading to dropped transactions;
- a synchronisation issue leading to stalls when syncing;

And some small features including database performance improvements and additional logging.

#### Upgrading private chain specification files.

All the chain specification files now have EIP-150 rules enabled by default. To continue using the chain add the `eip150Transition` key under `Engine/ethash/params` and set it to a future transition block as shown in [this example](https://github.com/paritytech/parity/blob/85eeb3ea6e5e21ad8e5644241edf82eb8069f536/ethcore/res/ethereum/morden.json#L13).

The key related to homestead transition has been renamed from `frontierCompatibilityModeLimit` to `homesteadTransition`.

1.3.5 is a hotfix release for the transaction propagation issue. Transaction pool limit is now calculated based on the block gas limit.

- Update appveyor rustc [beta] [#2521](https://github.com/paritytech/parity/pull/2521)
- Increase size of transaction queue by default [#2519](https://github.com/paritytech/parity/pull/2519)

## Parity [v1.3.4](https://github.com/paritytech/parity/releases/tag/v1.3.4) (2016-10-07)

Parity 1.3.4 release contains more optimizations to internal caching as well as stability improvements.

It also introduces an ability for miners to choose a transaction ordering strategy:

    --tx-queue-strategy S    Prioritization strategy used to order transactions
                             in the queue. S may be:
                             gas - Prioritize txs with low gas limit;
                             gas_price - Prioritize txs with high gas price;
                             gas_factor - Prioritize txs using gas price
                             and gas limit ratio [default: gas_factor].

## Parity [v1.3.0: "Acuity"](https://github.com/paritytech/parity/releases/tag/v1.3.0) (2016-08-12)

As well as many bug fixes, 1.3.0 includes a number of important improvements including:
- **Optimisations** Heavily optimised block/transaction processing core - up to 2x faster than 1.2 series.
- **Database compression** Databases take as much as 30% less storage than before.
- **State snapshotting** An installation synchronised from scratch in 1-2 minutes can be made after downloading the 140MB state snapshot. See [the wiki](https://github.com/paritytech/parity/wiki/Getting-Synced) for more information.
- **Process isolation** The networking/chain-synchronisation is now a fully independent process.

Incremental improvements include:
- Additional [RPCs](https://github.com/paritytech/parity/wiki/JSONRPC) for transaction tracing, state diffing, VM tracing, asynchronous transaction posting, accounts metadata and message signing.
- Improved logging, including for chain reorganisations.
- Added a `--fast-and-loose` option for additional speed-ups which can compromise integrity on a dirty shutdown.
- Column families to ensure maximal inter-database integrity.
- Key naming includes date/time of creation.
- Various improvements to networking robustness and performance.
- Solidity compilation supported through RPC if `solc` is available.
- Various improvements to the miner including [HTTP push work notification](https://github.com/ethcoreparitytech/parity/wiki/Mining#starting-it).

## Parity [v1.2.4](https://github.com/paritytech/parity/releases/tag/v1.2.4) (2016-08-09)

Parity 1.2.4 Is a maintenance release that fixes a [few](https://github.com/paritytech/parity/pull/1888/commits) issues related to mining and peer synchronization.
This release is marked as stable.

- Backports for beta [#1888](https://github.com/paritytech/parity/pull/1888)
- BETA: fixed trace_transaction crash when block contained suicide [#1782](https://github.com/paritytech/parity/pull/1782)

## Parity [v1.2.3](https://github.com/paritytech/parity/releases/tag/v1.2.3) (2016-07-31)

Parity 1.2.3 is a patch release that addresses network stability issues for both Ethereum HF and Ethereum classic chains and brings a few changes to the transaction tracing API.

#### Tracing API changes
- Added tracing for `CALLCODE`, `DELEGATECALL` and `SUICIDE`
- `trace_call` returns traces in flat format
- Added 2 new methods: `trace_rawTransaction` and `trace_replayTransaction`

Note that to continue using tracing features in this version you need to re-sync the blockchain. This can be done by using `parity export $HOME/ethereum-chain-backup.rlp` , deleting the database usually located at `~/.parity/906a34e69aec8c0d` followed by `parity import $HOME/ethereum-chain-backup.rlp`.

- [beta] Updating UI [#1778](https://github.com/paritytech/parity/pull/1778)
- tracing backport [#1770](https://github.com/paritytech/parity/pull/1770)
- Backport commits to beta [#1763](https://github.com/paritytech/parity/pull/1763)
- Deadlock on incoming connection (#1672) [#1675](https://github.com/paritytech/parity/pull/1675)
- [BETA] Removed DAO soft fork traces [#1640](https://github.com/paritytech/parity/pull/1640)


## Parity [v1.2.2](https://github.com/paritytech/parity/releases/tag/v1.2.2) (2016-07-16)

#### New
- DAO hard-fork.

DAO hard-fork implementation conforms to the [specification](https://blog.slock.it/hard-fork-specification-24b889e70703) and is enabled by default.

#### Changed
- `--reseal-on-txs` defaults to `own`.
- DAO soft-fork support has been removed along with related command line options.

#### Resolved issues
- `--db-cache-size` consuming too much memory.
  `eth_getWork` RPC response additionally includes the block number.
- Skipping transactions with invalid nonces when pushing to block.
- Update sealing just once when externally importing many blocks (#1541).
- Transaction tracing skipping simple transactions (#1606).
- Other small fixes and improvements.

## Parity [v1.2.1](https://github.com/paritytech/parity/releases/tag/v1.2.1) (2016-07-01)

#### New
- Options for more precise mining tuning (see below).
- Informative notification when block mined.
- HTTP signal on new work-package.
- Optimised database insertion for self-mined blocks.
- Short-circuit for local transaction gas-price approval.
- A number of issues related to mining have been fixed.

##### Mining options
- `--author` is now required for mining.
- `--reseal-on-txs` Specify which transactions should force the node to reseal a block. By default parity updates the seal on incoming transactions to reduce transaction latency. Set this option to `none` to force updates on new blocks only.
- `--reseal-min-period` Can be used to control how often a new pending block is generated if `none` is not selected on prior option.
- `--work-queue-size` Controls how many pending blocks to keep in memory.
- `--relay-set`  Can be used to enable more strict transaction verification.
- `--remove-solved` Move solved blocks from the work package queue instead of cloning them. This gives a slightly faster import speed, but means that extra solutions submitted for the same work package will go unused.
- `--notify-work` Accepts a list of URLs that will receive a POST request when new work package is available. The body of the POST message is JSON encoded and has the same format as `eth_getWork` RPC response.

##### RPC

`eth_getWork` RPC response additionally includes the block number.

##### DAO soft-fork

DAO soft-fork control options have been replaced by the single `--fork` option which disables the soft-fork by default.

#### Changes

- v1.2.1 in beta [#1492](https://github.com/paritytech/parity/pull/1492)
- (BETA) add artifacts [#1420](https://github.com/paritytech/parity/pull/1420)

## Parity [v1.2.0: "Security"](https://github.com/paritytech/parity/releases/tag/v1.2.0) (2016-06-24)

[Blog post](https://blog.parity.io/announcing-parity-1-2/)

#### New

- Transaction signing UI.
- IPC/RPC module.
- Optimised mining support.
- Windows build.
- DAO soft-fork support.

##### Transaction signing UI

This is a new framework for signing transactions. It fulfills three requirements:
- You should never have to type your passwords into a Dapp.
- No Javascript code should ever hold a secret.
- No transaction should ever be signed without the consent of the user.

The feature is enabled through the `--signer` flag. When enabled, the user must ensure at least one "Signer UI" is set-up for managing transaction confirmation. There are two such UIs available; one through a Google Chrome Extension, separately installable and the second through a special web page hosted locally. Set-up must be done once for each such UI, through copying and pasting a token from the output console of Parity into the UI. Specific instructions are given in the UI.

From this point on, no transaction may ever be signed by Parity except through one of these allowed Signer UIs, and no password should ever be entered anywhere else.

##### IPC/RPC module and Mist/Geth compatibility

Should be started with `--geth` to ensure Mist compatibility.

##### Optimised mining support

Numerous improvements and optimisations have been added to our mining implementation. A large "active queue" ensures that late-included transactions are included in the mined block without sacrificing older results from latent-reported `ethminer` results.

##### Windows build

We're happy to announce full Windows support with 1.2!

##### Soft-fork

This release includes support for the proposed [DAO soft-fork](https://docs.google.com/document/d/10RktunzjKNfp6Y8Cu4EhR5V9IqxEZq42LU126EYhWY4/pub). Upon upgrade, all mining nodes can vote for or against the soft fork (this is done through altering the block gas limit; a gas limit of at most 4M results in the soft-fork being triggered).

By default, nodes vote "for" the DAO soft-fork (and try to reduce the gas limit to 3.1M). To vote against the soft-fork (keeping it at 4.7M), run with `--dont-help-rescue-dao`. Not upgrading is not recommended; if the majority votes with a soft-fork, an upgrade will be necessary to mine on the correct chain.

#### Changed
- Fast pruning method is now default for a fresh sync.
- Web UI renamed to Dapps UI.
- JSONRPC and Dapps UI enabled by default.
- CLI options ending `-off` renamed to GNU-consistent prefix `--no-`.
- Dynamic gas-pricing (data feed and statistical techniques used to determine optimum gas prices).
