The Mozilla team this morning officially released the public version of Firefox 4.
The final code is based essentially on the first release candidate that shipped March 9, sans a few fixes. Bugs that surfaced after RC1 shipped were addressed in a follow up release candidate 2 for Windows, OSX and Linux that slipped out late last week.
The team plans to ship out a quick fix patch code named "Anteater" within the next two weeks if necessary. Then, a "Macaw" update is expected two to three weeks from today that will incorporate other fixes discovered during the first month of use.
The beta testing process began last June.
