2.9 is imminent (possibly later today) so probably best to hang on for that or stick with 2.7 for a little while longer if you are running the x12 core, are happy with it and don't need the latest fixes and features yet (mostly alternative ROM mapping functions in 2.9 it seems, changelog).
@Thread Thanks, as always everyone here is helpful

I also want to say to the vampire team, thanks for all the excellent work and continued support. I know that the 2.7 gold thread got a bit contentions at times, but I consider the vampire the most initiative thing to come to amiga in a long time. I have been using my vampirized A2000 more than any other amiga in many many years.
