I am learning to build custom image for my rpi4. I successfully built new image with all my needed packages and files based on 22.03.2. It is working fine so far. Now 22.03.2 is out and I will try to switch to new branch. I don't want to lose my 22.03.2 project(includes configuration/files/firmware images) just in case I need switch back to 22.03.2.
What is proper way to do it? and how to switch back to original branch?
