openHAB 2.2 Release

Half a year has passed since openHAB 2.1 and I am very happy that we still made it before Christmas, so that you have something nice to play with during the holiday season: openHAB 2.2 is out!

openHAB 2 has arrived!

Three years after initiating the Eclipse SmartHome project, I am proud to finally announce the general availability of openHAB 2.0, the first openHAB release that is based on Eclipse SmartHome!

They are now available in version 1.9.0 and can be used on existing openHAB 1.8 installations.
