As before, MAJOR, MINOR, MICRO,
and PATCHLEVEL are numbers, with an absent number equivalent to 0.
All versions should be distinguishable purely by those four
numbers. The STATUS_TAG is purely informational, and lets you know how
stable we think the release is: “alpha” is pretty unstable; “rc” is a
release candidate; and no tag at all means that we have a final
release.
