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. Release Candidate 1 could be released as early as October 2010 which means we could see Firefox 4 released around Thanksgiving/Christmas. Whilst on the subject of Firefox 3.7/4.0, there is currently not a code name assigned to this build. They have been labeled as Mozilla Developer Preview.

Whilst checking on the upcoming Firefox releases I noticed Mozilla has posted a possible release date for Thunderbird 3.0.5 as the week of May 24th. Well post update when I have more info.

For those of you expecting an update for the Firefox 3.5 and 3.6 builds today, you will need to wait a bit longer. Due to some blockers on the upcoming 3.6.4 build discovered earlier this week, the upcoming releases have been postponed. 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.
