I read about users confusion with wine version numbering scheme. Personally, I would redirect these confused users to the wiki page at wikipedia where it discusses what the numbers mean in a software version numbering scheme.

The MAME project had the same user confusion when it went from 0.99 to 0.100. Several of the users of MAME had expected the next version to be 1.00.
