KiCAD diff between two branches or at least between two tags or at least between two commits

https://github.com/rusefi/hw_microRusEfi/branches has branched of the most important (for me :) ) actively developed PCB

which we already have the script for automated per-commit diffs, a different use-case is a diff between two historic revisions that case should probably be a command line tool?

if we place script inside https://github.com/rusefi/kicad-libraries/ we would have it in https://github.com/rusefi/hw_microRusEfi/ via existing submodule reference

What else would get it? I don't think we need it for this repo, as the only kicad_pcb files are outlines.

Actions can be set up to run on release. That would work for repos that contain one piece of hardware.

https://github.com/rusefi/hw_microRusEfi has two boards - MRE and MRE test fixture
https://github.com/rusefi/hw_55_te would be one of public PnP boards
and a couple private PnP boards which are similar to https://github.com/rusefi/hw_55_te in terms of layout

With having more than one file per repo, I think having a version.txt file will be the best option.
Actions can be run on changes to particular files. I think we'd have to have an action for each board on a repo, unless I can come up with something better.
