Percona announces the GA release of Percona XtraBackup 2.4.8 on July 24, 2017. You can download it from our download site and apt and yum repositories.
Percona XtraBackup enables MySQL backups without blocking user queries, making it ideal for companies with large data sets and mission-critical applications that cannot tolerate long periods of downtime. Offered free as an open source solution, Percona XtraBackup drives down backup costs while providing unique features for MySQL backups.
New features:
- To avoid issues with MySQL 5.7 skipping redo log for DDL Percona XtraBackup has implemented three new options (
--lock-ddl,--lock-ddl-timeout, and--lock-ddl-per-table) that can be used to place MDL locks on tables while they are copied. - New
--check-privilegesoption has been implemented that can be used to check if Percona XtraBackup has all required privileges to perform the backup.
Bugs Fixed:
- xtrabackup would hang with
Waiting for master thread to be suspendedmessage when backup was being prepared. Bug fixed #1671437. - xtrabackup would fail to prepare the backup with
6th page is not initializedmessage in case server didn’t properly initialize the page. Bug fixed #1671722. - xbstream could run out of file descriptors while extracting the backup which contains many tables. Bug fixed #1690823.
- When a table was created with the
DATA DIRECTORYoption xtrabackup would back up the.frmand.islfiles, but not the.ibdfile. Due to the missing.ibdfiles backup then could not be restored. Bug fixed #1701736. - Percona XtraBackup incorrectly determined use of
master_auto_postionon a slave, and thus generated invalidxtrabackup_slave_infofile. Bug fixed #1705193. - Percona XtraBackup will now print a warning if it encounters unsupported storage engine. Bug fixed #1394493.
- Percona XtraBackup would crash while backing up MariaDB 10.2.x with
--ftwrl-*options. Bug fixed #1704636. - xtrabackup
--slave-infodidn’t write the correct information intoxtrabackup_slave_infofile when multi-source replication was used. Bug fixed #1551634. - Along with
xtrabackup_checkpintsfile, xtrabackup now copiesxtrabackup_infofile into directory specified by--extra-lsndiroption. Bug fixed #1600656. - GTID position was not recorded when
--binlog-infooption was set toAUTO. Bug fixed #1651505.

What kind of issues? 5.7 only? Where can we read more about it? Some details would be greatly appreciated. Thank you.
Backup of MySQL 5.7 would abort if there were DDLs. This feature adds an option to block DDLs. You can find more information in the original bug report.
Thank you very much Hrvoje.
