Firefox 3.1b3 - на следующей неделе, Firefox 3.1b4 - через 6 недель после b3.

Mike Shaver сегодня пролил свет на график выхода бет Firefox 3.1:

As David mentioned in his previous thread, we have been holding beta 3 on a handful of JS patches, chiefly "upvar" (https://bugzilla.mozilla.org/show_bug.cgi?id=452498). That patch is getting close, but the continuing and great work on fixing other final-release blockers means that we're accumulating a lot of changes on the 1.9.1 stream that would benefit from wider feedback from our beta testers. To that end, we're going to wrap up beta 3 in the next week regardless of upvar status; a 4th beta will follow approximately 6 weeks after, as a vehicle for more testing of tracemonkey, video, places and other eagerly-awaited improvements as well as feedback from beta 3.
