## Parity [v1.8.1](https://github.com/paritytech/parity/releases/tag/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](https://github.com/paritytech/parity/pull/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.
