Hi @debieo
Server version 4.13 (together with Analytics Platform version 4.4) is scheduled for release at the end of this month (i.e. just over a week from now). However, this is a .0 release which is not recommended for production. We will release a production ready release a little later, you can follow this thread to get a notification on the release.
