After a series of alpha and beta releases, some of which have been released into the wild, we're happy to announce that we created a release candidate for the 5.4 release.
We have fixed a couple of bugs, updated some internal libraries and improved performance and stability.
This release is available from the Maven Central Repository, or as a direct download.
Please give it a spin and let us know how it is working for you. If you find any bugs, please report them on the users' mailing list or create a JIRA issue.
Happy testing!
