On Linux: Kernel Release Number, Part II you can read Linus say this:
(Of course, the rules do matter in the sense that there has to be some
point to the consistency. You can have a consistent rule that "the
ChangeLog entries must rhyme", and I think it's a great rule, and I
encourage anybody who wants to to set up such a "rhyming kernel tree", but
that doesn't mean that it makes a lot of difference to people ;).
Changelog in rhyme... ROFL.
