Great news to share: grid services now updated to OpenSim 0.9.0. This should fix a lot of the teleport issues and border crossings issues with var regions. Older simulators are still functional with the new services and teleporting between 0.8 and 0.9 simulators has been working well too. If you are running 0.9 and have run across any bugs please open a mantis asap with detailed information as well as clear method to reproduce.
