Hi, Greg.

(Sorry to reply to such an old post.)  I trust what you're saying about
the history of the NetBSD stable branches, but that doesn't seem to
match what I read on the NetBSD release glossary and graphs page:

There it says the following about stable maintenance branches:

  What you will find on a stable branch is the last release (major
  or minor) plus whatever bug fixes and enhancements which will be
  going into the next minor release, pulled up from the NetBSD-current
  development branch. For example, if the latest release is 6.0, the CVS
  branch for it is "netbsd-6" which can be thought of as containing an
  alpha version of the following 6.x releases.

An "alpha version" does not sound stable to me. :-)  Maybe the wording
should be changed to not call it an "alpha" version, or maybe a more
clear statement about the stability of the stable branch (like your
statement above) should be added?
