Parity v1.8.6 (2018-01-10)

Parity 1.8.6 fixes a critical issue with the database eventually filling up user's disks. Upgrading is highly recommended as it will significantly improve your user experience. As a bonus, this release should enable users with slower hard-disk drives to catch up with the latest block again. Also, warp-sync performance was significantly improved. Please note, that the initial database compaction after upgrading might temporarily reduce the node's performance.

In addition to our gas price histogram, this version now allows you to dynamically set the default gas price as percentile from the last 100 blocks (it defaults to median: 50).

--gas-price-percentile=[PCT]        Set PCT percentile gas price value from
                                    last 100 blocks as default gas price
                                    when sending transactions.

Last but not least, this release also fixes consensus issues with the Expanse chain enabling Byzantium. If you run Parity configured for Expanse, you might have to resync your chain after the upgrade.

Parity v1.8.5 (2017-12-29)

Parity 1.8.5 changes the default behavior of JSON-RPC CORS setting, detects same-key engine signers in Aura networks, and updates bootnodes for the Kovan and Foundation networks.

Note: The default value of --jsonrpc-cors option has been altered to disallow (potentially malicious) websites from accessing the low-sensitivity RPCs (viewing exposed accounts, proposing transactions for signing). Currently domains need to be whitelisted manually. To bring back previous behaviour run with --jsonrpc-cors all or --jsonrpc-cors http://example.com.

The full list of included changes:

• Beta Backports (#7297)
  • New warp enodes (#7287)

Parity v1.8.4 (2017-12-12)

Parity 1.8.4 applies fixes for Proof-of-Authority networks and schedules the Kovan-Byzantium hard-fork.

• The Kovan testnet will fork on block 5067000 at Thu Dec 14 2017 05:40:03 UTC.
  • This enables Byzantium features on Kovan.
  • This disables uncles on Kovan for stability reasons.
• Proof-of-Authority networks are advised to set maximumUncleCount to 0 in a future maximumUncleCountTransition for stability reasons.
  • See the Kovan chain spec for an example.
  • New PoA networks created with Parity will have this feature enabled by default.

Furthermore, this release includes the ECIP-1039 Monetary policy rounding specification for Ethereum Classic, reduces the maximum Ethash-block timestamp drift to 15 seconds, and fixes various bugs for WASM and the RPC APIs.

Parity v1.8.1 (2017-10-20)

Parity 1.8.1 fixes several bugs with token balances, tweaks snapshot-sync, improves the performance of nodes with huge amounts of accounts and changes the Trezor account derivation path.

Important Note: The Trezor account derivation path was changed in this release (#6815) to always use the first account (m/44'/60'/0'/0/0 instead of m/44'/60'/0'/0). This way we enable compatibility with other Ethereum wallets supporting Trezor hardware-wallets. However, action is required before upgrading, if you have funds on your Parity Trezor wallet. If you already upgraded to 1.8.1, please downgrade to 1.8.0 first to recover the funds with the following steps:

1. Make sure you have 1.8.0-beta and your Trezor plugged in.
2. Create a new standard Parity account. Make sure you have backups of the recovery phrase and don't forget the password.
3. Move your funds from the Trezor hardware-wallet account to the freshly generated Parity account.
4. Upgrade to 1.8.1-beta and plug in your Trezor.
5. Move your funds from your Parity account to the new Trezor account.
6. Keep using Parity as normal.

If you don't want to downgrade or move your funds off your Trezor-device, you can also use the official Trezor application or other wallets allowing to select the derivation path to access the funds.

The full list of included changes:

• Add ECIP1017 to Morden config (#6845)
• Ethstore optimizations (#6844)
• Bumb to v1.8.1 (#6843)
