I'm pleased to announce that jberet-core 1.2.7.Final & 1.3.2.Final were released on Nov 8, 2018.  These are micro maintenance releases aimed for bug fixes.  They both include the fix for the following issue:

JBERET-459 JBeret batches fail following timed out transactions

If you encounter the same problem as described in the above issue, I'd encourage you to upgrade to either jberet-core 1.2.7.Final, or 1.3.2.Final.  The same fix has also been pushed to the master branch, and will be included in the next planned release (1.4.0.Beta1).
