I do not consider wikipedia to contain the absolute truth, but it's
often a good source of a general consensus.

"In principle, in subsequent releases, the major number is increased
when there are significant jumps in functionality, the minor number is
incremented when only minor features or significant fixes have been
added, and the revision number is incremented when minor bugs are fixed."

If TYPO3 version numbers are used differently a big warning sign might 
be needed :-)
OTOH Ingo might not find it necessary, because it was never stated 
anywhere that a .x version is a minor update ;-)
