Yeah. Why? I just got version 5.
Was I asleep for a month?
it's their (ridiculous IMO) new "fast-release" schedule. I think this was spurned by two things:
-Chrome versions adding up fast (version 12 currently, I believe).
-One of the firefox devs read a book on agile programming and is now an expert.
As far as I'm concerned, the differences between Firefox 4 and Firefox 5 come nowhere near what ought to be required for a major version change. I mean, sure, there is no real rule saying what does and does not constitute such a change, but to me, changing the major version for a few tweaks and speedups, and fixes, seems a bit dishonest, if not just confusing.
TO make things worse there is already discussion about how a
nightly build of Firefox 8 is faster than Chrome 14. Chrome is on version 12. what the heck is going on
Next we'll have MS release a press release saying that while IE 9 is slower than Chrome 12 and Firefox 5, IE 13 will be faster than Chrome 19 and Firefox 11. And announcing how their version numbers will no longer be sequential but be numbered using the fibonacci sequence.
