Functionality Added or Changed


     * Offline backups are no longer supported by mysqlbackup.
       As a result, a number of options used for offline backup
       operations have been removed. See What's New in MySQL
       Enterprise Backup 8.0?
(http://dev.mysql.com/doc/mysql-enterprise-backup/8.0/en/what-is-new.html)
       for details. (Bug #27429244)

     * The server option --secure-auth, deprecated since MySQL
       5.7.5, is no longer supported by mysqlbackup. (Bug
       #27265328)

     * Servers' use of the keyring_encrypted_file
(http://dev.mysql.com/doc/refman/8.0/en/keyring-encrypted-file-plugin.html)
       and keyring_aws
(http://dev.mysql.com/doc/refman/8.0/en/keyring-aws-plugin.html)
       plugins is now supported. See Working with
       Encrypted InnoDB Tables
(http://dev.mysql.com/doc/mysql-enterprise-backup/8.0/en/meb-encrypted-innodb.html)
       for details. (Bug #27127898)

     * Information on the executed GTIDs is now included in the
       mysqlbackup output and the backup log when the backed up
       server has GTIDs enabled. (Bug #25978803)

     * The backup_history table now includes a server_uuid
       column, which stores the value of the server_uuid of the
       backed up server.

     * The options --ssl and --ssl-verify-server-cert, already
       deprecated in MySQL Enterprise Backup 4.1, have now been
       removed. Use the --ssl-mode option instead to configure
       the security mode of your connection to the server.

     * MySQL Enterprise Firewall
(http://dev.mysql.com/doc/refman/8.0/en/mysql-enterprise-firewall.html)
       is now supported.

     * A new option, --tls-version, specifies the protocols
       mysqlbackup permits for encrypted connections to MySQL
       servers.

     * A file now tracks information of external tablespaces
(http://dev.mysql.com/doc/refman/8.0/en/tablespace-placing.html)
       for a backup or restore in JSON format. See
       description for tablespace_tracker
(http://dev.mysql.com/doc/mysql-enterprise-backup/8.0/en/meb-files-backed-up-summary.html#meb_file_tablespace-tracker)
       in Types of Files in a Backup
(http://dev.mysql.com/doc/mysql-enterprise-backup/8.0/en/meb-files-backed-up-summary.html#meb-backup-files)
       for details.

     * The relay log for a backed-up slave server, instead of
       being restored always to the data directory on the target
       slave server, is now restored by default to the same
       location it was found on the backed-up slave server. It
       can also be restored to a different location specified
       with the new --relay-log option.

     * The binary log for a backed-up server, instead of being
       restored always to the data directory on the target
       server, is now restored by default to the same location
       it was found on the backed-up server. It can also be
       restored to a different location specified with the new
       --log-bin option.

     * The buffer size for cloud transfers can now be specified
       using the new --cloud-buffer-size option. See Cloud
       Storage Options
(http://dev.mysql.com/doc/mysql-enterprise-backup/8.0/en/backup-cloud-options.html)
       for details.

     * HTTP Basic Authentication and non-chunked transfer are
       now supported for backup and restore using OpenStack
       Swift-compatible object storage services. Two new
       options, --cloud-basicauth-url and
       --cloud-chunked-transfer, have been introduced for these
       purposes. See Cloud Storage Options
(http://dev.mysql.com/doc/mysql-enterprise-backup/8.0/en/backup-cloud-options.html)
       for details.

Bugs Fixed


     * After restoring a full backup, if the following restore
       of an incremental backup changed the restore location of
       the undo log, either mysqlbackup hung, or the restored
       server failed to start. With this fix, mysqlbackup quits
       with a proper error ("Undo tablespace in the base backup
       not found") in the situation.
       Users should make sure the undo log location does not
       change between successive restores of a full and an
       incremental backups, or of two incremental backups. (Bug
       #27530916)

     * mysqlbackup failed to backup to an Amazon S3 cloud
       storage. (Bug #27231229)

     * An apply-incremental-backup operation corrupted the
       non-InnoDB files in its target backup when the sizes of
       those files are smaller in the incremental backup than in
       the target backup. (Bug #27001934)

     * mysqlbackup could not establish a connection to the
       server with a Unix socket using the option
       --protocol=SOCKET. (Bug #26977679)

     * A number of memory leaks were observed when running
       mysqlbackup. They have now been fixed. (Bug #26495834,
       Bug #26373259, Bug #26093563, Bug #26423820, Bug
       #26497245)

     * After applying an incremental backup created with the
       --incremental-with-redo-log-only option to a full backup,
       the full backup's binary log became corrupted. (Bug
       #26403452)

     * On macOS, mysqlbackup failed to determine the relay log
       file name correctly and thus could not back up the relay
       log for a slave server. (Bug #25574605)

     * mysqlbackup only accepts values for --ssl-mode in upper
       case. With this fix, the option's value has become case
       insensitive. (Bug #25548088)

     * In a Group Replication
(http://dev.mysql.com/doc/refman/8.0/en/group-replication.html)
       setting for MySQL servers, when changes were made
       to one group member and a backup was taken on another,
       the relay log for the replication applier was missing
       from the backup, so that the restored server could not be
       started. (Bug #25534078)

     * mysqlbackup could not restore the auto increment values
       in tables and the corruptions flags for indexes onto a
       server. The tasks are now made possible by having
       mysqlbackup copying onto the restored sever blocks of
       redo logs that cover the during from the latest
       checkpoint to the time of backup, so that the server can,
       after restart, restore the incremental values and the
       corruption flags using those blocks.
