Check differences between (nightly) releases

I’m not super familiar with Git yet. How can I check the differences between two nightly builds of Ionic?

In the ionic-bower repo, all nightly releases have a nice and neat version number. In the original Ionic repo, where the actual code is that I want to compare, I can’t find such tags.

For instance how could I see the differences between nightly-1712 and nightly-1713?

I would expect that the CHANGELOG.md file is being auto-updated but that doesn’t seem to be the case.

This should show you all the changes since beta 1
