How to compare two tags with git?

Question

I would like to do a diff between two tags and committed changes between those two tags. Could you please tell me the command?

Answer 1

For a side-by-side visual representation, I use git difftool with openDiff set to the default viewer.

Example usage:

git difftool tags/ tags/

If you are only interested in a specific file, you can use:

git difftool tags/: tags/:

As a side-note, the tags/s can be replaced with es if you are interested in diffing branches.
