There is some manual overhead, but I think the alternative is worse (breaking changes go untracked). It's a good idea to have an ongoing changelog like this, and I don't see a way to manage it other than manually.
Your point around consistency is an important one. The example in the linked Nessie PR looks pretty good to me, with a short blurb for each item and a link to the PR. I suppose the exact criteria that necessitate an entry to the changelog are also a little unclear, but in general if there's a user-facing change that a single reviewer feels warrants an entry I feel we're better off adding it. I agree with JB that this feels similar to updating documentation when you make a code change. --EM On Thu, May 15, 2025 at 11:09 PM Yufei Gu <flyrain...@gmail.com> wrote: > It does seem to introduce quite a bit of manual overhead.
