I will chime in here and hopefully paraphrase what Ted and Mats have

Major release numbers 4.x, 5.x of the LSB should be a signal to both
ISVs and Distribution vendors of:

o major new functionality
o changes to binary compatibility

Minor release numbers (X.1, X.2, etc.) should be

o tightening up of specifications
o fixes to the specification
o *minor* *additions* to the specification for new functionality

At Digital we had a third level to the numbering scheme (X.x.a) where
the "a" was an architecture dependent release.

Coupled with this numbering scheme is a roadmap that is at least two
major releases out, so people could plan where to do their work.
Therefore the customers could make a decision if they were going to
support a "4.0" release, a "4.1" release or skip directly to a "5.0"

Sorry if this email is redundant to y'all, but the numbering scheme
worked well for us, and our customers appreciated the planning it
