Firefox

Yeah it could work too. Like you said though it's subjective and internal arguments about what deserves to be big or not sounds tiring :p. For marketing large changes, inventing a buzzword seems to be working well enough.

I guess to each their own, but I kind of like not knowing the version. I just use Firefox and if I really care what's new I can look at the changelog, or see it in the what's new pop-up.
