MariaDB Server 10.3 Release Candidate Now Available

Today, we are releasing MariaDB Server 10.3.5, which is our first Release Candidate for 10.3.

Now feature complete, our user and customer base can move from reviewing and testing new features to integrating MariaDB Server into their staging environment to prove it against existing applications and to enhance their applications with new use cases provided through the abundance of new and exciting features in MariaDB Server, like temporal data processing. Another strong focus of this version is database compatibility where we have added several new features. With MariaDB Server 10.3, it’s even easier to migrate from legacy database systems to open source MariaDB.
