  • Implemented the support of the lz4 compression algorithm. More information in PXB-1857.

Bugs Fixed

  • xbcloud did not update date related fields of the HTTP header when retrying a request. Bug fixed PXB-1874.
  • xbcloud did not retry to send the request after receiving the HTTP 408 error (request timeout). Bug fixed PXB-1875.
  • xtrabackup did not accept decimal fractions as values of the innodb_max_dirty_pages_pct option. Bug fixed PXB-1807.
  • If the user tried to merge an already prepared incremental backup, a misleading error was produced without informing that incremental backups may not be used twice. Bug fixed PXB-1862.
