Maintainer notes:

A number of critical bugs, that showed up since the last version released for Fedora, has been fixed: problems with Spider SE on armv7hl and several problems with replication.

The package source is NOT the officially released tarball for 10.4.10 version, but a later snapshot of upstream Git, in order to contain some critical patches without which the package won't be fit for release to Fedora.
Thus most of the 10.4.11 version release notes apply too: https://mariadb.com/kb/en/library/mariadb-10411-release-notes/

Highlighted changes:

Option "wsrep_cluster_address" in "/etc/my.cnf.d/galera.cnf" now MUST be configured, or the server will refuse to start, when replication is enabled (option "wsrep_on" is set to "1")
That means, when you install "mariadb-server-galera" package, the server won't start out-of-the-box anymore and requires to be configured prior first start.

Plans for future:

A 10.4.11 version should be released soon. If no issues would be found, I will try to pack it into base Fedora Rawhide (= NOT as a module; but the module will be also available)
This step is planned for a long time: https://fedoraproject.org/wiki/Changes/MariaDB_10.4 and has been publicly anounced.
