MariaDB 11.8.2 now returns a NULL value instead of a 0 (zero) value for UNIX_TIMESTAMP(), which breaks our application and possibly others. So be sure to test carefully before upgrading!.

Why upgrading too quickly is not always a good idea. This morning, we upgraded to the #MariaDB 11.8.2 LTS release, and this afternoon we encountered the following issue:. Unsupported DB! MariaDB version 110802 is newer than maximum allowed 110599.Warning! Unsupported MariaDB.

It looks like this weeks #MariaDB releases have a regression (more locking, lock wait timeout, etc.). So do NOT upgrade for the moment! Downgrade seems to solve the problem again. MDEV-36766, MDEV-36772, MDEV-36759.

The next #MariaDB release (2025-01) can replicate from #MySQL 8.0 Master. Not sure why you would need that, but good to know. Have some people missed the migration a few years ago?.

We upgraded our first production #MariaDB 10.11 database to 11.4.3. It worked quite well. A few issues were solved quickly. Could cause some operational problems with huge databases. More details we will tell you in a consulting engagement.

With the new Backup- and Recovery-Manager Version 2.3.0 for #MariaDB and #MySQL, a partial physical database restore (only one database/schema) is much faster and easier than with conventional on-board tools.
