How to determine latest production release from a git master branch?

I am still a newbie on git. When I did a git clone ... on any packages, it mostly downloads from the master branch.

My understanding is a master branch should contain both development and release codes.
If so, is it possible to find out the latest (production) release version from the downloaded master branch?

If every release is marked with an annotated tag, git describe is what you need (cite from man page):

git-describe - Show the most recent tag that is reachable from a commit

If your last released version is for example 2.6.9, git describe will give you the following output:

2.6.9-<NUMCOMMITS>-g<CURRENTREV>

If your current branch points directly to 2.6.9, NUMCOMMITS and CURRENTREV will not be printed and the command only yields 2.6.9.

However, if you did some commits since 2.6.9 (e.g. 3), NUMCOMMITS will be 3 and CURRENTREV will be the 7 chars of the abbreviated last commit hash (e.g. 2597536):

2.6.9-3-g2597536

Same could be achieved for unannotated tags using the --tags switch:

git describe --tags

The OP precises in the comments that "release version" isn't about having binaries (deliveries) in the repo, but getting the versions which are used to produced delivery.

git tag alone is not well suite, because the order isn't always pertinent.

However, as i explained in "How to sort git tags?", this would give the right order (with git 2.0+)

git tag -l --sort=refname "v*"
# or
git tag -l --sort=version:refname "v*"

v17
v16
...
v9
...
v1
