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

Subject: Re: [lustre-discuss] Upgrade to 2.11: unrecognized mount option

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