I upgraded XFRM to the 4th beta version today via command line, and noticed that unlike XFMG it does not rebuild permissions after upgrading. Wasn't sure if that was deliberate or if I missed something.
Ah, ok. I was prompted to complete the upgrade when I refreshed the ACP and it completed rebuilding permissions. Prior to upgrading XFRM I did XFMG so maybe that was because of that?
