Once again Mozilla has renumbered a future release in mid-build. They did this last year with Firefox 3.1 which became 3.5 with Beta 4 release in April. Firefox 3.7 has been renumbered as Firefox 4 with the upcoming Beta 1 release possibly as early as June 2010.

While these blockers do no affect the 3.5.10 release, Mozilla will not push out this release until 3.6.4 is ready to ship. No word yet on an updated release date, I am hoping to have some news in the next couple days for the end of the week Release Recap post.
