  Waiting for 3.0 to land and emancipate us from our 'master's. Bringing about true social change, one SHA at a time.

  It's unfortunate that change IDs aren't considered. There was a discussion [1] in 2025, and it has resurfaced a couple of times since.Basically, the idea is to attribute a new kind of ID to an initial 'change'. During review, or whenever a commit is rebased, the change ID is kept, whereas the commit of course changes. This allows tooling to identify all previous versions of a change, and is what enables "per-commit" code review à la Gerrit [2] (which IMO is a much better experience than the branch-review-squash model that GitHub normalized). It's also used in jj, although I'm not familiar with that.As of today, any tool that wants a change ID needs to somehow encode it in commit message bodies. The proposed discussion was about making a change ID a standard header field that git would natively keep across rebases.[1] https://lore.kernel.org/git/Z_OGMb-1oV0Ex05e@pks.im/T/#mf941...[2] https://gerrit-review.googlesource.com/Documentation/user-ch...

  Why not transitioning to SHA3 directly? IIRC lenght extension attacks are not currently feasible on SHA2, but still theoretically possible.

  Will we ever get integer commit references like we have in mercurial ?

  `git add --resolved` is a wonderful idea, and definitely something I would start using.

  It appears that BitBucket also does not currently support SHA256 hashes.https://jira.atlassian.com/browse/BCLOUD-23729

  Does it mean that when switching trop sha1 to sha256 you need to forcepush and rewrite all history? Wouldn’t that be a massive source of potential vulnerabilities?

  I'm still looking for a simple way to "save" a snapshot of my work in git, without all the ceremony of stashing etc

  Are they going to fix all the bad defaults in Git 3.0?

  Why am I not surprised that GitHub is dragging its heels on sha256? I assume they just aren't able to change fundamental parts of their system now. So no sha256, no IPv6 etc. They can only sprinkle bits around the edges.

  > It is a binary file optimized for both space efficiency and quick access. Since then, it has been possible to create a repository that uses a reftable rather than the old file-based mechanism,Good, are there (m)any other plans to ditch the slow files and use proper database? Or is it only reserved for various post-git competitors?
