On regressions: MDEV-36765: JSON Histogram cannot handle >1 byte characters #4080 "Starting from 10.11.12, Incorrect handling of UTF-8 characters (and other character sets requiring more than a single byte representation) in the minimum/maximum positions of a table during the execution of ANALYZE TABLE tbl PERSISTENT FOR ALL resulted in an endless loop consuming more memory and prevented the server from terminating." histogram_type=DOUBLE_PREC_HB <https://mariadb.com/kb/en/server-system-variables/#histogram_type> as a packaged configuration would prevent a default ANALYZE TABLE table hitting this otherwise the patch: The minimal patch is https://github.com/MariaDB/server/commit/39bb34b9c536b8fd750643ff2a688def4d9... (my fault for making JSON types utf8mb4 in JSON_UNQUOTE, so please have my apologies) MDEV-36871 mariadb-backup incremental segfault querying mariadb_backup_history #4112 "Mariabackup since MDEV-30000 <https://jira.mariadb.org/browse/MDEV-30000> (10.11.12, 11.4.6, 11.8.2) has a regression when using --incremental-history-name which incorrectly handled the forcing of the innodb checkpoint causing Mariabackup to crash. Also discovered that in the mysql.mariadb_backup_history the format column when --stream=mbstream was used was recorded as "tar". This has been corrected to "mbstream". Under Windows the full path of mariabackup.exe was used as in the "tool" column of the history table and this is now only recording the executable name without the path. Resilience against user specified --incremental-history-name or --incremental-history-uuid which exceeds the field size also produces an error rather than behaving erroneously." So this is impacting those that use incremental backups and history tables. fixed by: https://github.com/MariaDB/server/commit/2d1e019f4f5ada670aa6baaea0a126a4d32... Few others are listed https://jira.mariadb.org/issues/?jql=project%20%3D%20MDEV%20AND%20fixVersion...) There's a few Galera ones worth looking at, and one XA bug.

Hi all MariaDB packagers!
At https://repology.org/project/mariadb/versions I can see 54 entries about MariaDB 11.8.2 in distros. The most notable one still missing is Fedora Rawhide. Michal, did you run into any issues?
Others with 11.8.2 already in their distro: Have you come across any major regressions or things to highlight?
In Debian and Ubuntu there are zero bugs reported about MariaDB 11.8 series specifically, so I am not aware of any particular regressions.

Hi MariaDB packagers!
MariaDB 11.8.2 is finally here and thus a long-term supported version for next 5 years! If you have not already, check out
https://mariadb.org/11-8-lts-released/
Looking at https://repology.org/project/mariadb/versions I see that a handful of distros already have the new MariaDB 11.8 LTS released for general availability last week. Congrats to Chrisian Hesse for being the fastest (non-automated) human importer and landing 11.8.2 in Arch Linux on June 4th!
I uploaded MariaDB 11.8.2 to Debian yesterday. In Debian the amount of additional metadata is rather extensive and building MariaDB on 16 different CPU architectures is also a lot. If you only now started working on 11.8, and you run into any build or test issues, you might want to check out the Debian packaging and patches as all those generic issues have been fixed in Debian: https://salsa.debian.org/mariadb-team/mariadb-server
Debian may also have a bunch of other packaging files that may be useful for others too. For example
https://salsa.debian.org/mariadb-team/mariadb-server/-/blob/debian/latest/de...
lists every single system variable that has been added, removed, deprecated or had the default value changed. You can see this information also for every single minor release imported to Debian by looking at the git history of the directory
https://salsa.debian.org/mariadb-team/mariadb-server/-/tree/debian/latest/de... .
Additionally the file
https://salsa.debian.org/mariadb-team/mariadb-server/-/blob/debian/latest/de...
summarizes how users and permissions are best managed.
