I never understood why people were all that hung up about the version numbering. The number now is the point release, they just dropped the major version number, which was actually pretty arbitrary (see below).
So instead of stressing that it's version 26, call it 4.26 and be happy.
Long boring part:
Major version numbers historically were saved for major - potentially incompatible - releases. So, if you were using v3.x of something, be careful about upgrading to v4.x, right? Two reasons why that totally doesn't apply with browsers, though
1) there is extremely rarely any compatibility breakage. Only in the case of people writing to proprietary and deprecated features, and those are basically broken by design (hi, ActiveX). Go to zombo.com and be welcomed to a site that has been working since 1999.
2) For the sake of the Web, people really need to keep moving, upgrading with the web. If people feel they need to stay back with v3.x or whatever "just to be safe" then developers can't implement upcoming standards that are getting to be really important. The death of XP (more precisely, IE 6) is a great thing for the web in general. (Yes I know IE8 runs in XP... it's not all that great either).
Version numbers aren't something that the web user should ever really worry about. If it were that important, then each web page really should have a version number.
