Drupal update to specific version (not dev) with git I have a Drupal folder made with command:

git clone --branch 7.x https://git.drupalcode.org/project/drupal.git 


Now I want to update it to the actual version (7.67). When I run

git pull origin 7.x


or 

git pull origin 7.67


Every time I get the 7.68-dev version, not 7.67. What am I doing wrong?
I know how to get the specific version with composer, but in this situation I need to get it with git pull command.
Just to expand on this for future reference:

Releases in git are created as tags.  To see the available releases, do the initial pull from the repo, then you can see the available tags with the command:

git tag


To check out the specific release, do:

git checkout [tag-id]


You will see a message about previous head and current head.

Check that you are on the correct tag with:

git status


It should indicate that you are currently in a headless state.
