As you might have noticed on github, the team has been quite active on master during last months; after almost twenty 3.0.x bug fix releases, we're eventually working on a new minor, 3.1.0.
Among the most relevant changes that are coming in the new minor there are default Java 8 target, revisited project structure / testsuite and a major cleanup of old and deprecated APIs. On the last topic, Ron has been preparing a very good document you might want to read for easy migration of old (RESTEasy 2.3 style) code.
Clearly, bug fixes and new features are coming too in 3.1.0! We're trying to deal with as much pull requests as possible (keep sending them, thanks!) and one that I'd like to mention here is from Julien Viet who contributed a new server adapter for Vert.x integration.
We've tagged two 3.1.0 Beta releases so far, both available as artifacts on Maven repository. I'm currently waiting for the last one to be merged into WildFly master (PR here).
If you have some time, consider early checking your projects with the new 3.1.0 and feel free to report back any issue (btw, as a reminder, note we have new mailing lists since some months!). We plan to go CR soon and hopefully release at before the end of October.
Stay tuned :-)
