mozilla-central is CLOSED for Firefox release candidates

[Benjamin Smedberg]

Per the triage meeting today, mozilla-central is now CLOSED so that
release engineering can prepare Firefox 4 release candidates. This means
that NO CHANGES may land, even things which may have Firefox or Mobile
blocker flags.

Rob Sayre is preparing a plan for the mechanics of how we reopen the
tree for both pending changes for Firefox Mobile 4 and new work for
Firefox 5. This includes all the related details about how we manage
nightly testers, branching, feature landings, and the schedule. Until
this plan is finalized, the tree will remain absolutely frozen.

Please direct any followup to mozilla.dev.planning.
