Can't get past v3.6.4

[AltairWorke]

It's been over a year since I installed NetBox and I've done at least one upgrade to get me to v3.6.4. I wan't to move to 4.x but I understand from the release notes that I have to go through v3.7.x to get some database upgrades needed for 4.

However, if I do a git pull from my NetBox directory my current version of 3.6.4 is the newest listed. No amount of git checkout v3.7.8 variation will get me anything but an "did not match any file(s) known to git" error.

If I just do a git pull origin master IT WILL download v4.0.6, but obviously a ./upgrade.sh ultimately fails because of the Missing 'users_user' Relation in Database

How can I force the version. I am assuming it has something to do with the output of the following? But I can't figure out what to change.
