very desktop-centric review..

Traditionally SuSE used major version numbers that just incremented every
year and minor version numbers for the (quarterly) releases within a year.
They changed it when release cycles got longer, but I don't know how the
current system works. If there is any.

So, no. A SuSE user could never rely on major/minor version numbers to
actually tell you how much changed in a release. It's much better to just
read the release notes.
