CHANGELOG-1.3.md

Note: Parity 1.3 reached End-of-Life on 2017-01-19 (EOL).

Parity v1.3.15 (2016-12-10)

This patch release fixes an issue with syncing on the Ropsten test network.

• Backporting to stable #3793

Parity v1.3.14 (2016-11-25)

Parity 1.3.14 fixes a few stability issues and adds support for the Ropsten testnet.

• Backporting to stable #3616

Parity v1.3.13 (2016-11-18)

This release fixes an issue with EIP-155 transactions being allowed into the transaction pool.

• [stable] Check tx signatures before adding to the queue. #3521
• Fix Stable Docker Build #3479

Parity v1.3.12 (2016-11-16)

This stable release enables EIP-155/160/161/170 hardfork at block 2675000 (1885000 for test network).

• [stable] EIP-170 #3462
• #3035 Backport to stable #3441

Parity v1.3.11 (2016-11-11)

This is a maintenance release for the stable series to delay the EIP-155/160/161 hard fork transition. Update from 1.3.10 is mandatory. It also deprecates and disables the old Parity UI.

• [stable] Disable HF and UI #3372
• [stable] EIP-155 update with Vitalik's new test vectors (#3166) #3190
• Backport EIP-150 to stable #2672
• Create gitlab-ci.yml for stable #2517

Parity 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
• Backporting to beta #3149
• apply post-consolidation migrations after consolidating (BETA) #3048
• [beta] Fix the brainwallet functionality. (#2994) #3005
• Bumping json-ipc-server #2989
• Backports for 1.3.10 #2987

Parity 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
• Fixing botched merge #2767
• Backports for beta #2764
• Introduce EIP150 hardfork block for ETC #2736
• [beta] fix issues with no test dir present (#2659) #2724

• [beta] Fix migration system, better errors #2661

Parity 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.

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.

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

Full changes

• Backports to beta #2592

Parity v1.3.6 (2016-10-11)

• Backports to beta v1.3.6 #2571
• Use global state cache when mining #2529
• Transaction queue limited by gas #2528

Parity v1.3.5 (2016-10-08)

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
• Increase size of transaction queue by default #2519

Parity 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].
