Google does a lot of A/B testing, so listing new changes may be pointless as the new features may be available only to select few.
Also developers have no incentive to document changes. It’s a hassle to compile a list of changes since last release, and people don’t read the Changelog for every release, especially with auto updates on.
I’d be great if they could at least use an LLM to compile the Changelog
A developer here, I usually list user - facing changes in the Changelog.
Even if the changes are not listed, general “bug fixes and performance improvements” is a worthwhile update too. These updates can contain fixes to annoying UX glitches, or really speed up the app, if a new faster API endpoint was added to the backend, and app change is needed to make use of it. You will also get security updates, to the app and its bundled libraries which is important nowadays.
