Seems to be frozen now. D'oh, I was too late to get my first FreeBSD feature (woohoo!) added to the 11.2 release notes. So I'll just randomly post it here in case anyone cares:
The procctl(2) syscall has been updated to support
PROC_PDEATHSIG_CTL, similar to Linux® PR_SET_PDEATHSIG. [r333162]
The RELEASE is functionally equal to the last Release Candidate (eg RC3); any functional change - eg anything other than documentation - would trigger another RC.
The "official" announcement is scheduled for tomorrow and, until it hits, the ISO images, etc., are still subject to change.
