# ejabberd 17.04
- URL: https://www.process-one.net/blog/ejabberd-17-04/
- Published: 2017-04-10T22:00:00.000Z

- Author: Jérôme Sautret

Less than a month after previous release, ejabberd 17.04 is out with bug-fixes and new features: Redis and SQL backends can now be used to store some RAM tables, the same way Mnesia is doing.

This release fixes few regressions from previous refactor. If you have troubles using PEP or using external modules with ejabberd 17.03, upgrade to 17.04 should fix everything.

Refactor efforts are still in progress. If you’re a developer, consider ‘jlib’ module as obsolete and do call common helpers (like type convertors) from the new ‘misc’ module instead.
