In "git w.x.y.z", the decoding is:
w: not likely to change short of a complete rewrite or something that
is quite incompatible (i.e., will probably remain "1" for quite a
while)
x: when this jumps, it is a "big" version change, meaning there may be
some minor incompatibilities or new ways of doing things. For
example, 1.5.0 introduced a lot of usability changes and the
separate-remotes layout became the default. In 1.6.0, we stopped
shipping "git-*" in the PATH, and started using some new packfile
features by default. And so on. If you want to know more, see
Documentation/RelNotes/1.?.0.txt.
y: when this jumps, it is a new release cut from master that does not
have any "big" changes as above. There will be new features and
some bugfixes. See RelNotes/1.7.?.txt for examples of what gets
included.
z: when this jumps, it is a bugfix release based on the feature
release w.x.y. See RelNotes/1.7.5.?.txt for examples.
Getting more to your actual question, I don't know that we ever use any
particular name like "major" or "minor" for any of them. We do tend to
use the terms "feature release" for w.x.y releases and "bugfix release"
for w.x.y.z.
