For the first problem there is a change. I don't know how to change code in github but basically UNIT_POWER no longer exists. If you can change code yourself, edit the tags.lua to say UNIT_POWER_UPDATE.

EDIT I've looked at the latest tags.lua and it has already been changed so download the latest clone :)
