CyberNet News announced earlier Mozilla has released Beta 4 of Firefox 3. I am not all the certain if this is the final version of Beta 4. Normally, Mozilla does not do version releases first thing on Mondays, the release notes still say Release Candidate plus there was a re-spin or two on the Windows builds just on this past Friday. Also on Friday was the Community Test Day where they did use the release candidate for testing. Further Mozilla has a ‘releases’ section designated for ‘Betas’ (http://www.mozilla.com/en-US/firefox/all-beta.html) and Beta 4 is not listed there. The Weekly Update Meeting is in a couple hours and that should clarify when Beta 4 will be released.
Edit: From today’s Weekly Update Meeting, Beta 4 on track to ship today.
