The list of officially supported databases has been updated:

  • MariaDB 10.6 is out of support and thus Nextcloud dropped support for it.
  • The minimum supported version of MariaDB is now 10.11 LTS.
  • MySQL 8.0 is out of support and thus Nextcloud dropped support for it.
  • The minimum supported version of MySQL is now 8.4 LTS.
  • MySQL 9.7 is released as a new LTS version and is now supported by Nextcloud.

Note on MySQL 9+
MySQL 9+ dropped support for MD5, some parts of the Nextcloud ecosystem might still rely on it. You need to make sure that after upgrading to MySQL 9+ you load the MySQL component for MD5 support, to do so run this on your MySQL 9+ server:

  `INSTALL COMPONENT 'file://component_classic_hashing';`

supported database version

  • PG18 is now recommended (> PG14 supported)

32-bits support

If you still use 32-bit system it’s time to plan an upgrade. The topic is really controversal since some time and 32-bit support becomes harder every day. 2 years ago the decision was made to avoid hard removal of 32-bit support, but it’s clear it will disappear sooner than later..
