Changelog between console image snapshots

I seek clarity on the changelog between various snapshot releases of the console image[1].

On a related note, I have built a console image using OMAP image builder[2] was hoping to rebuild the console and tag it to a particular release/version. How do I do that?

I understand that there is at least one git repo, such as bootscripts[3] on the BBB debian image. How can I map them to the commit corressponding to the snapshot version.

And are there other files on the image that are version controlled similarly? Thanks
