The latest code freeze for Firefox 3.5 beta 4 (formerly 3.1) deadline has slipped. The reason being due to some remaining outstanding priority 1 issues.
“Code freeze was scheduled for today, but as just announced, some of the P1 blockers have not yet been resolved and so we’ve delayed the freeze to wait for these fixes,” said Firefox’s Director Mike Beltzner.
Beta 4′s release is still slated for next week. A list of remaining P1 blockers can be found on Bugzilla.
