> I'd just like to know why every release is a major number increment. At the rate they are going we are going to be at Firefox 39 in 3 years. Why couldn't we stick with the major.minor release numbering where only major upgrades got a new major number?
Firefox and Chrome both bump the major version number every 6 weeks, because they *do* include changes in those 6-week updates that break earlier stuff. Not bumping the major version number would be potentially misleading, since people assume minor version numbers do not introduce incompatibilities.
Firefox also had the reason that Chrome already used that numbering scheme, so it makes sense to standardize on one that is familiar to people already.
Side note: I'm surprised by the comments here on LWN. I expect Slashdotters to say "Mozilla and Google are just trying to get high version numbers, it's all marketing, blah blah", but here? I expect more from LWN readers! ;)
