• Tested on 10.6.24, the issue is not reproducible anymore. (MDEV-30456)

• InnoDB could crash if the definition of the InnoDB persistent statistics tables were incorrect. (MDEV-31740)

• SIGSEGV in maria_rtree_split_page | maria_rtree_add_key (MDEV-31766)

• MariaDB upgrade fails when using innodb_encrypt_tables=ON and innodb_checksum_algorithm=crc32, which is not the default. innodb_checksum_algorithm=crc32 is used only if explicitly specified or if the table has been created which MariaDB 10.4 or a prior version (MDEV-36556)

• Assertion `bulk_insert == TRX_NO_BULK' failed in trx_t::assert_freed from innodb_shutdown (MDEV-36771)

• Fix spider view protocol failures for higher versions (MDEV-37204)

• ALTER TABLE allows adding unique hash key with duplicate values (MDEV-37296)

• When the server was started in read-only mode with encryption enabled, the fix ensures that InnoDB avoids creating any encryption thread.Testing: encryption.innodb-read-only(MTR Test) contains scenario that can be used to test this change. (MDEV-37299)

• InnoDB partition table disallow local GTIDs in galera (MDEV-37373)

• The minimum value of the parameter innodb_ft_min_token_size was increased to 1, similar to the parameter ft_min_word_len. (MDEV-37423)

• Parallel slave worker crashes During Backup at retrying (MDEV-37453)

• decimal_digits_t trips GCC -Wconversion (MDEV-37477)

• The performance of innodb_adaptive_hash_index=ON was improved further. We introduce the parameter innodb_adaptive_hash_index_cells that can be configured with SET GLOBAL. The specified value will be effectively multiplied by innodb_adaptive_hash_index_parts, because each partition will contain its own hash table. (MDEV-37482)

• mariadb-dump -T did not encode table names like the server did for frm files, so some tables can be created in the server, but not dumped with mariadb-dump -T, for example, a table con on Windows. (MDEV-37483)

• Fix crash by correctly updating SP instruction state after instruction re-parsing , preventing dangling reference. (MDEV-37489)

• Failure to detect corruption during backups of Aria table (MDEV-37520)

• Fix server_audit rwlock Performance Schema instrumentation (MDEV-37555)

• Assertion failure sql_base.cc:3927: bool open_and_process_routine (MDEV-37581)

• The forced use of THD accessor functions hurts InnoDB performance (MDEV-37619)

• Fedora MariaDB depends on mysql-selinux (MDEV-37680)

• Frequent timeouts of the test innodb.innodb_bug38231 (MDEV-37743)

• Assertion `transaction.is_streaming()' failed in void wsrep::transaction::adopt(const wsrep::transaction&) (MDEV-30764)

• Exchange partition with virtual columns fails (MDEV-34033)

• Parameterized PS converts error to warning, causes replication problems (MDEV-34046)

• Assertion failure in online_alter_log_row or server hang upon replicating REPAIR on mysql.gtid_slave_pos (MDEV-34134)

• Recovery of Aria transactional tables did not work in big-endian machines like s390x and Sparc.(MDEV-34914)

• Innodb did not handle case-sensitivity on Windows correctly prior to this fix in its data dictionary, converting all names to lowercase. This resulted in inconsistency, if data directory was in case-sensitive NTFS directory, as well as in situations when data directory was copied from Windows to Unix systems. This is fixed in this patch. (MDEV-34953)

• ALTER TABLE could fail to update InnoDB persistent statistics. (MDEV-35163)

• Assertion `nests_entered == cur_sj_inner_tables' failed in JOIN::dbug_verify_sj_inner_tables on SELECT (MDEV-35206)

• ASAN: use-after-poison in st_select_lex::print (MDEV-35816)

• Corrected python3 compatibility of myrocks_hotbackup thanks to contributor i18n.site (MDEV-36010)

• Explain format=json with a DML statement containing a derived table and some manner of execution abortion, a timeout or kill will lead to an assertion or crash. (MDEV-36034)

• view-protocol: sys_vars.slave_parallel_threads_basic (MDEV-36385)

• only mtr test has been fixed (MDEV-36710)

• The PrivateDevices=false directive in the systemd service has been removed as it was an old kernel incompatibility that this directived worked around. With this, the MariaDB is restricted further. Those using InnoDB on raw devices will need to add an override for this. See https://mariadb.com/docs/server/server-management/starting-and-stopping-mariadb/systemd#useful-systemd-options (MDEV-36721)

• ALTER TABLE tbl_a ADD PARTITION (PARTITION pt2) MSAN uninitalized read (MDEV-36723)

• Fix COALESCE and IFNULL functions to use - (i) argument nullness, (ii) type conversion safety of fallback values to decide nullability of result. (MDEV-36851)

• Fixed bug in maria-backup where maria-backup would crash during the 'maria_recovery' part. This could happen if server was doing repair or creating indexes while the backup was running. (MDEV-36860)

• Improve runtime dependency packaging on Windows (MDEV-36904)

• On Windows, when MSI package is installed, with ADDLOCAL parameter passed to msiexec.exe, and Visual C++ Redistributable package is not installed on the target machine, installation may fail during "create database" step. (MDEV-36938)

• MyRocks storage engine can no be built on aarch64 non-linux platforms (MDEV-37001)

• sql/wsrep_allowlist_service.cc:40:27: runtime error: member call on null pointer of type 'Wsrep_schema' (MDEV-37136)

• Killed query with side effects without error (MDEV-37198)

• galera.galera_sst_encrypted LeakSanitizer: detected memory leaks (MDEV-37206)

• mtr galera_3nodes.galera_garbd_backup test failures (MDEV-37209)

• Ensure that Annotate_rows is always written direct after GTID information, before any table_map events. Before this patch the event could be written in a random position in the binary log. This change make the place of the Annotate_rows event predictable. When mixing transactional and not transactional tables in the same transaction, the Annotate rows event was not always written in the case of a rollback. This is now fixed. (MDEV-37356)

• Downcast of address to Item_func_eq but of type Item_func_equal in opt_split.cc(add_ext_keyuse_for_splitting) found with UBSAN (MDEV-37438)

• There was a very small chance of InnoDB crashing or misbehaving after an attempt to reduce innodb_buffer_pool_size. (MDEV-37447)

• It appears that some error conditions don't store error information in the Diagnostics_area. For example when table_def::compatible_with() check fails error message is stored in Relay_log_info instead. This results in optimistically identical votes and zero error buffer size breaks wsrep-lib logic as it relies on error buffer size to decide whether voting took place. To account for this, first try to obtain error info from Relay_log_info, then fallback to Diagnostics_area. If that fails use some random data to distinguish this condition from success. This requires bumping of the application protocol to 8 since vote message generation algorithm has changed. (MDEV-37494)

• The galera_new_cluster script was installed into the scriptdir in the 2025 Q3 releases. It previously was in the bin dir. The difference is only noticeable on bintar releases. (MDEV-37497)

• Make Server Debug + Clang compile ready (MDEV-37502)

• UBSAN: nullptr-with-nonzero-offset/pointer-overflow in row_log_apply_ops (MDEV-37626)

• BsonGet_String and JsonGet_String with a NULL argument resulted in an empty string warning. This now has an "Argument is NULL" warning. (MDEV-37633)

• IS TRUE incorrectly converts outer join to inner (MDEV-37653)

• CHECK TABLE…EXTENDED could flag bogus corruption on a column prefix index. (MDEV-37659)

• innodb.sys_defragment fails sporadically in CI with wrong result (MDEV-37669)

• During workload after crash recovery, an incorrect (too large) innodb_buffer_pool_pages_dirty could be reported. (MDEV-37677)

• main.lotofstack /main.sp-error fails in MSAN+Debug (MDEV-37705)

• LOCATE(X,Y,NULL) is not NULL (MDEV-37740)

• Table Charset Mismatch (Primary/Replica) via Event (MDEV-37744)

• Lock checks for secondary indexes were unnecessarily accessing some history and could access freed BLOB pages that correspond to column prefixes. (MDEV-37753)

• gcov doesn't work on macOS (MDEV-37791)

• main.repair_symlink-5543 broken on macOS (MDEV-37851)

• Using mytop with DBD-MariaDB and host=localhost specified resulted in an unexpected error because the driver did not expect a port 3306. Contribution thanks to Jean Weisbuch. (MDEV-37852)

• sys_vars.thread_cache_size_func fails sporadically (MDEV-37890)

• main.public_privileges fails sporadically (MDEV-37893)

• Some performance schema tests fail on builds without WSREP (MENT-1944)

• If the user specifies some tls-related parameters in spider table creation with odbc/mariadb backend (unlikely), these parameters could be ill-formatted in the odbc connection string, causing them to be ignored by the driver. (MENT-2407)
