@Gary LaPointe -

So I’m still a little confused on the what is considered “minor”.

Clearly minor is not getting me the development releases.
Minor will get me 3.7.1 (right?)

But will minor updates get me 3.8? Is a 0.1 upgrade “minor”?

I’d think a jump from 3.x to 4.0 would be considered major…?

Saying that a jump from 3.x to 4.0 is major would be a version schema where X is a major update, and X.Y is a minor update.

That's not how versioning works in WordPress. In WordPress:

X: no such version
X.Y: major
X.Y.Z: minor

So, there is no such thing as WordPress Version 3, nor will there ever be anything such as WordPress Version 4.

Major WordPress versions are 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, and soon: 3.8.

Minor versions are 3.6.1, 3.7.1, etc.

And here's the kicker: versions 2.9, 3.0, and 3.1 are all equally major versions. Likewise, versions 3.9, 4.0, and 4.1 will all be equally major versions.

This is a common point of confusion - and, I suspect, perhaps a contributor to some people not updating from version X.0 to version X.1 or later.
