  Solaris jumped from 2.6 to 7 (the "2." is now implicit). Of course, Windows NT jumped from 4.0 to 2000. ;)

      Vista was 6.0. Windows 7 was 6.1 and 8 was 6.2 (8.1 was 6.3). They finally bumped up the version to 10 with Windows 10.

    Java went from 1.4 to 5. Although not completely; it took until 9 for the actual directory names etc to change.
