jPOS 2.1.8 has been released. New development version is 2.1.9-SNAPSHOT and jPOS 3.0.0 (aka 'next').
See ChangeLog for details.
We will continue to maintain the 2.x.x series for a long while, so you can consider the 2.x.x series an LTS version, but all the fun and new features will happen in 3.x.x.
