[git] How to get the changes on a branch in Git

Similar to several answers like Alex V's and NDavis, but none of them are quite the same.

When already in the branch in question

Using:

git diff master...

Which combines several features:

  • it's super short
  • shows the actual changes

Update:

This should probably be git diff master, but also this shows the diff, not the commits as the question specified.
