Major (or public) releases will have an extension
that is divisible by 0.05 (e.g., 0.75, 0.80, 0.85).
Major releases are expected to be stable.
Minor (or development) releases will have an extension
that is divisible by .01 (e.g., 0.71, 0.72, 0.73).
As of release 0.90.0,
the "pico" version number (the third number) also carries a meaning :
only even numbers are used for releases, the odd numbers are the
development versions between releases.
This means 0.90.1 is a development version (not a release),
0.90.2 is probably the release to follow 0.90.0.
There has been a time in which minor releases were not very stable.
Writing this is tempting the odds,
but minor releases have been stable for a long time,
we expect them to remain so.
Releases will be accompanied by announcements to
comp.windows.x.motif and various newsgroups and newsfeeds.
