openethereum/docs/CHANGELOG-1.2.md

Note: Parity 1.2 reached End-of-Life on 2016-11-07 (EOL).

Parity v1.2.4 (2016-08-09)

Parity 1.2.4 Is a maintenance release that fixes a few issues related to mining and peer synchronization. This release is marked as stable.

• Backports for beta #1888
• BETA: fixed trace_transaction crash when block contained suicide #1782

Parity 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
• tracing backport #1770
• Backport commits to beta #1763
• Deadlock on incoming connection (#1672) #1675
• [BETA] Removed DAO soft fork traces #1640

Parity v1.2.2 (2016-07-16)

New

• DAO hard-fork.

DAO hard-fork implementation conforms to the specification 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.

Full changelog

• DAO hard-fork (#1483) #1636
• Backports for beta #1628
• don't batch best block for branches (#1623) #1626
• Merge bugfixes from master to beta #1605
• (BETA) using block options cache instead of general cache for rocksdb #1613
• Backport sealing fixes to beta #1583
• v1.2.2 in beta #1581
• Skipping transactions with invalid nonces when pushing to block. (#1545) #1547

Parity 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
• (BETA) add artifacts #1420

Parity v1.2.0: "Security" (2016-06-24)

Blog post

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. 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).
