I'm not normally one to try any x.0.0 release, but TAC just suggested we look at it as a fix to an ongoing AP crash issue we're having on a batch of 505 we just recently rolled out. Obviously we'll do the usual research and lab it out as much as we can, but that's never a perfect match for going live.
Has anyone out there tried 8.7.0.0 in a production environment yet, and if so, how has it worked out for you?
