There's a certain arbitrariness to this analysis, since all that is being considered is an increment in the major version number. If the author were looking at operating systems this way, Apple hasn't released a new operating system in nearly 10 years! (OS 10.0 Cheetah was released on 3/24/01)
Not to offend anyone, but Chrome major version releases tend to feel relatively incremental compared to what I had come to expect from Firefox.
The developer tools have been steadily improving, apart from that I can't recall to much exactly.
Will be interesting to see if Firefox can keep to their new release schedule after 4. Otherwise it seems that Chrome just iterates to fast compared to Firefox. Chrome 9 is a long way ahead of Firefox 3.6, sure Firefox 4 might even it up but if every release has this kind of beta time Chrome will just keep skipping ahead.
Hey, there you go. I noticed some great additions to the Inspector.
I'm pretty sure that the reason I can't come up with the differences is that the change is so gradual. I know Chrome has been improving, it's just not a dramatic change like FF 1 to 2 or IE 6 to 7. But Chrome 4 to 9 doesn't even seem like a dramatic change. if they were using normal versioning, I don't even know if it would be time for Chrome 2.0 yet.
Why would that be offensive? Chrome major version number changes are a: typically invisible to the user, and b: chosen for merely engineering reasons. If tech blogs didn't exist to tell people about major version changes in chrome most user's wouldn't have the slightest clue what version they were running.
tl;dr Chrome's major version releases are supposed to be incremental.
These really do reflect the most significant releases of each browser, regardless of arbitrary major/minor/micro version number changes... Firefox 3.6 was as major a release in that universe as Chrome 8 was in theirs.
Check the Wikipedia pages for each major browser to see just how much changed in the versions represented. (Perhaps I should link them!)
