It was sent to lustre-discuss (among others). Maybe I’ve fallen foul of Eli’s spam filter :-)

I think you missed it – It came out a few days ago, and Peter Jones announced it in what I assume was the usual manner.  Maybe there’s a “which lists were sent to” issue?

OT: Did I miss the mail announcing Lustre 2.11 or all the recent 2.11 mails early adapters?

I suspect it's automatically added by SELinux, but I couldn't tell you
