Features
MariaDB Server
Versioning
MariaDB version numbers follow MySQL's numbering scheme up to version 5.5. Thus, MariaDB 5.5 offers all of the MySQL 5.5 features. There exists a gap in MySQL versions between 5.1 and 5.5, while MariaDB issued 5.2 and 5.3 point releases.
Since specific new features have been developed in MariaDB, the developers decided that a major version number change was necessary.
Licensing
The MariaDB Foundation mentions:
MariaDB Server will remain Free and Open Source Software licensed under GPLv2, independent of any commercial entities.
Third-party software
MariaDB's API and protocol are compatible with those used by MySQL, plus some features to support native non-blocking operations and progress reporting. This means that all connectors, libraries and applications which work with MySQL should also work on MariaDB—whether or not they support its native features. On this basis,

At the time of founding in 2013 the Foundation wished to create a
governance model similar to that used by the
Eclipse Foundation. The Board appointed the Eclipse Foundation's Executive Director Mike Milinkovich as an advisor to lead the transition.
The MariaDB Foundation's first sponsor and member was MariaDB Corporation Ab that joined in 2014 after initial agreements on the division of ownership and roles between the MariaDB Foundation and MariaDB Corporation.
E.g. MariaDB is a registered trademark of MariaDB Corporation
Ab, used under license by the MariaDB Foundation. MariaDB Corporation Ab was originally founded in 2010 as SkySQL Corporation Ab, but changed name in 2014 to reflect its role as the main driving force behind the development of MariaDB server and the biggest support-provider for it. Foundation CEO at the time,
Simon Phipps quit in 2014 on the sale of the MariaDB trademark to SkySQL. He later said: "I quit as soon as it was obvious the company was not going to allow an independent foundation."
Simon Phipps was CEO of the Foundation from April 2013 to 2014. Otto Kekäläinen was the CEO from January 2015 to September 2018.
