MariaDB 10.3 is an evolution of MariaDB 10.2 with several entirely new features not found anywhere else and with backported and reimplemented features from MySQL.

MariaDB 10.3.7 is a Stable (GA) release.

Notable changes of this release include:

MyRocks Storage Engine is now Stable (GA)
Spider Storage Engine is now Stable (GA)
Two new ALTER TABLE ... ALGORITHM options, INSTANT and NOCOPY, which allow operations that would require any data files to be modified, or that would require rebuilding the clustered index respectively, to be refused rather than potentially perform slowly, as well as other ALTER TABLE improvements. (MDEV-13134, MDEV-14168)
The embedded server library now supports SSL when connecting to remote servers.
New system variable secure_timestamp for restricting the direct setting of a session timestamp (MDEV-15923)
New status variables feature_json for monitoring JSON functionality usage and feature_system_versioning for system versioning.
Remove InnoDB 5.7 version number from MariaDB 10.3 onwards (MDEV-16172)
Fixes for instant ADD COLUMN (MDEV-14906, MDEV-15060, MDEV-15871, MDEV-16065)
Various performance fixes and code cleanup, including clean up InnoDB parameter validation (MDEV-12218)
Fixed hangs on shutdown (MDEV-13779) and EXPORT (MDEV-13987)
As per the MariaDB Deprecation Policy, this will be the last release of MariaDB 10.3 for Debian 7 Wheezy and Fedora 26
 
Thank you for correction.

How to check which versions are available in DA?
 
The changelog above is a comparison to the previous 10.3 release. It was never in DA.

The real and significant changelog (if DA team add it and somebody wish to upgrade from 10.2 to 10.3) is the following:

https://mariadb.com/kb/en/library/upgrading-from-mariadb-102-to-mariadb-103/

This one sounds really bad (what about customers coming from other webhost with a mysql dump from previous version? I guess they could use a phpMyAdmin export?):

mysqldump in MariaDB 10.3 includes logic to cater for the mysql.transaction_registry table. mysqldump from an earlier MariaDB release cannot be used on MariaDB 10.3 and beyond.

You are wrong. Old backups can be restored on 10.3 with no problems.

What it says is that you cannot make backups on MariaDB 10.3 with a mysqldump binary for older version. For example you won't be able to backup a 10.3 database with a 10.1 mysqldump util. Who is ever doing that anyway?

FYI: I tried to run it on FreeBSD 11.1 and failed. The "make" and "make install" commands were successful; however trying to run it was not. The /var/log/messages got the following error upon startup:

(mysqld), uid 0: exited on signal 11 (core dumped)

So... Don't be in hurry to upgrade I guess.
