This release is the current GA (Generally Available) stable release in the 2.0 series.
This release contains over 20 fixed bugs, some of the more significant bugs fixed are:
- After creating a full compressed backup, performing a compressed/uncompressed incremental backup would fail because xtrabackup_checkpoints was compressed. This has been fixed by omitting xtrabackup_checkpoints from compression, so that a full backup could be used for incremental backups without decompression. Bug fixed #977652 (Alexey Kopytov).
- Streaming backups with –stream=tar would fail if the file size was bigger than 8GB. Fixed by changing the libarchive format from USTAR to restricted PAX which supports bigger file sizes. Bug fixed #977998 (Alexey Kopytov).
- innobackupex was calling the tar utility unconditionally when streaming ib_lru_dump and xtrabackup_galera_info. Which led to a broken stream when the xbstream format was used. Bug fixed #983720 (Sergei Glushchenko).
- XtraBackup binary could fail with the “log block checksum mismatch” error when reading the partially written log block. Bug fixed #1015416 (Alexey Kopytov).
