Release highlights

Percona XtraBackup 8.1.0-1 is based on MySQL 8.1 and fully supports the Percona Server for MySQL 8.1 Innovation series and the MySQL 8.1 Innovation series. This release allows taking backups of Percona Server 8.1.0-1 and MySQL 8.1.

In the Innovation series, the server shifts to a component infrastructure, the keyring’s functionality remains the same. Percona XtraBackup 8.1.0-1 supports the component keyring_vault. Users can back up their encrypted data after they convert from the keyring_vault plugin to the keyring_vault component.
