In this release, we adopted a PR naming convention (Angular's, PR 1615) that should facilitate auto-generation of release notes, so this may be the last hand-written release note, organized by committer. From now on, I believe they'll be organized by type (new features, bug-fixes, CI changes, etc.).

Also, this is the last release with tag and release title formatted as just `f"{version}"`; starting with the next one, the tag name with be `f"v{version}"` and the release title will be `f"Version {version}"`.

jpivarski removed `std::cout` from ArrayBuilder and `print` from several of the tests.

ianna migrated ArrayBuilder to the new GrowableBuffer: PR 1542.

Moelf fixed a misleading error message: PR 1544.
