I'm not sure if you've been using Merge Requests here, but if you do you can compare each version against another. There are two dropdowns near the top of the "Changes" tab: "Compare <master> and <latest version>". Here you can compare versions against the target branch and other versions. > I think GitHub and Gitlab both can handle ... commit ranges, can they > not?

At GitLab we keep track of the commit IDs a branch has been (maybe only if there is a Merge Request for that branch, I'm not sure). We can use this information to compare versions. I think, to some people in this thread, the use-case for Change-IDs is pretty similar: you want to tie information about two commits together. If there is a branch, you have this information, but in a mail-based workflow (or in Jujutsu) there is no branch. In that case a Change-Id can fill that gap. >> If you make a comment on a _specific commit_, the feature doesn't kick >> in at all. GitLab just tells you that this comment was made "on an >> outdated change in commit xyz". As I mentioned, you might need to create a MR to retain/see this information, I'm not entirely sure. > The point is that GL demonstrates that these things can be done.

If you don't do that, you can't. Having a Change-Id embedded in the commit, retains that information in Git's DB. -- Toon
