But not sure when. We are very busy with some urgent stuff behind the scenes. Once that is sorted we will (re)start working on the (very overdue) maintenance release.

If you'd like to assist in making the updated release happen sooner, then please feel free to help out. TKLDev (our build infrastructure) is free open source as is the phplist appliance build code. If you need a hand then post back and I'll do what I can to head you in the right direction...
