rewritten Git-History of Branch main

[cocker-cc]

Hello,

Question: is it true, that the Git-History of Branch main is rewritten frequently?

I come to this Question, because our Workflow is to take main and to add our Changes on top in a separate Branch, currently some 60 Commits.
To follow your proceeding Development we then regularly rebase our Branch against main. This used to work flawlessly.

But in recent Times – perhaps since one Year or so – this leads to Rebase-Conflicts, and further Investigation reveals, that the old main is not there anymore as it was.

Example: currently our Commits sit on Top of 0e725b4c, which was main's last Commit then in 2024-02, but today I find this very Commit in main with a different Commit-ID and the former Commit-ID is not existing anymore.

The most recent common Commit-ID between main and our Branch is identical to the former master from 2020. All later Commits have gotten new Commit-IDs. So the Rebase starts there which is annoying, because I have to handle Conflicts, which have nothing to do with my Work at all.
