I am a software developer, but I have no direct knowledge of how Apple
It would appear from the structure and history, however, that the first
digit is a major release milestone, i.e. 10.0, 10.1, 10.2, 10.3, 10.4 and
that the numbers date back all the way to NextStep/OpenStep days.
The second position (the letter) would be most likely major integration
points, or internal milestones. I would *guess* that they may be related
to internal development lines (branches) and therefore favor the integration
point viewpoint, but again I have no internal insight.
One reason I favor the branch integration position is that the profusion
of letter revisions is waining as OS X matures. There are likely fewer
discussions internally as to "which way to proceed" which would cause
fewer branches, and fewer integration points.
