MariaDB 10.10 preview releases now available

We are pleased to announce the fourth MariaDB series release under the  new release model,  MariaDB 10.10.0.

Maturing MariaDB more quickly

One of the purposes of the new model is to get features into the hands of users more quickly, in a form which supports stability by allowing the new feature to be more easily tested, separate from other new features being developed at the same time.
