I agree that the numeric MAJOR.MINOR.PATCHLEVEL is what seems most
familiar to me, though I don't see a problem using a letter for the
patchlevel either.  My comment about sorting is not an issue as the
schemes are not mixed, so I think package systems can use the either
scheme unchanged.

Using odd/even for stable/unstable may have some implications for the
development process, so it may not be suitable for any project, but if
used:  I suspect the first minor series (X.0.Z) would usually be
unstable, so unless there is precedence, it may be most convenient if
the odd minor versions are stable.
