The next-gen rule engine (NGRE) of openHAB 2.5 has now become the official rule engine within openHAB. Good news is that your rule DSL files are not impacted by this change and should run smoothly on it. The only change you’ll have to look our for in your rules is the fact that rules now use Java Time API instead of Jodatime, so some expressions need to be slightly adapted.
