Now 2.13.15 is released, a Scala 3 user may be wondering - what changes are relevant to me? Should I upgrade the library?
Release notes are not much helpful in this respect, as most of the changes are in the compiler.
Filtered closed issues and closed PRs lists tell something, but are all library issues marked with library?
The release notes would communicate library bug fixes; the issues are labelled.
I don’t know what the plan is to “unfreeze” the library, but I assume they have a plan which they will eventually share.
Tickets are, well, usually properly labeled.
I’d suggest using git for this. In the scala/scala repo, use a command such as git log -p v2.13.14..v2.13.15 -- src/library. A few of the PRs are just cleanups and doc; looks like the only actual changes are in PRs 10793, 10810, 10816, 10818.
Often not. We only release-note especially significant fixes. (None of these four PRs seemed to me to qualify.)
