  • Performance regression in fil_space_t::try_to_close() introduced in MDEV-23855 (MDEV-30775)
  • InnoDB recovery hangs when buffer pool ran out of memory (MDEV-30551)
  • InnoDB undo log truncation fails to wait for purge of history (MDEV-30671
  • MariaDB crash due to DB_FAIL reported for a corrupted page (MDEV-30397)
  • Deadlock between INSERT and InnoDB non-persistent statistics update (MDEV-30638)
  • InnoDB hang on B-tree split or merge (MDEV-29835)
  • Performance regression in locking reads from secondary indexes (MDEV-30357)
  • Improve adaptive flushing (MDEV-26055)
  • Make page flushing even faster (MDEV-26827)
  • Purge misses a chance to free not-yet-reused undo pages (MDEV-29593)
  • InnoDB temporary tablespace: reclaiming of free space does not work (MDEV-26782)
  • Deadlock between CHECK TABLE and bulk insert (MDEV-30798)
  • UPPER() returns an empty string for U+0251 in uca1400 collations for utf8 (MDEV-30661)
  • System-wide max transaction id corrupted after changing the undo tablespaces (MDEV-30311)
  • Fix miscount of doublewrites by Innodb_data_written (MDEV-31124)


  • mariadb-backup doesn't utilise innodb-undo-log-directory (if specified as a relative path) during copy-back operation (MDEV-28187)
  • mariabackup issues error messages during InnoDB tablespaces export on partial backup preparing (MDEV-29050)
  • mariadb-backup does not copy Aria logs if aria_log_dir_path is used (MDEV-30968)
  • Race condition between buffer pool flush and log file deletion in mariadb-backup --prepare (MDEV-30860)


  • Fixed a deadlock on parallel slave involving full image Write event on the sequence engine (MDEV-29621)
  • Fixed an attempted out-of-order binlogging error on slave involving ALTER on the sequence engine (MDEV-31077)
  • Corrected non-versioned master to versioned slave replication on no-unique attribute table (MDEV-30430)
  • Mended encrypted binlog master to error out to gtid-mode slave when master could not decrypt a binlog file (MDEV-28798)
  • Refined optimistic parallel slave to error-exit without any hang (MDEV-30780)
  • Ensured SHOW-SLAVE-STATUS is processed on the parallel slave having a necessary mutex always intialized (MDEV-30620)
  • Fixed the slave applier to report a correct error when gtid_slave_pos insert fails for some (engine) reasons (MDEV-31038)
  • Made parallel slave reports in performance schema consistent with that of show-slave-status (MDEV-26071)


  • Split Materialized optimization is improved to re-fill the materialized table only if necessary. The fewer number of table refills is taken into account when choosing query plan, too (MDEV-26301)
  • New optimizer_switch option, hash_join_cardinality, is added. It is off by default. When set to ON, the optimizer will produce tighter bounds for hash join output cardinality. (MDEV-30812)
  • Queries using SELECT DISTINCT some_expression(aggregate_function()) could produce wrong query result. (MDEV-20057)
  • ANALYZE FORMAT=JSON now prints more information about Block Nested Loop joins: block-nl-join element now has r_loops, r_effective_rows and r_other_time_ms fields (MDEV-30806, MDEV-30972).
  • A GROUP BY query with MIN(primary_key) in select list and primary_key<>const in the WHERE could produce wrong result when executed with "Using index for group-by" strategy (MDEV-30605)
  • EXPLAIN could erroneously report that Rowid Filter optimization is used for partitioned tables. Partitioned tables do not support it. (MDEV-30596)
  • A bug in selectivity computations for SINGLE/DOUBLE_PREC_HB histograms could cause wrong estimates to be produced. This could cause the optimizer to pick sub-optimal query plans (MDEV-31067).

Docker Official Image

  • Add replication setup to containers contributed by Md Sahil (MDEV-29762)
  • Added LTS tags for easier identification of LTS releases:
    • lts-jammy
    • lts
