Subject: [PATCH 1/2] Add CHANGES.md

List each release with a `## VERSION (YYYY-MM-DD)` header, newest first,
so that scripts can extract the release notes. The notes for releases
since 2020 are summarised from the git history; older releases have only
their header. Dates are those in PackageInfo.g at the release tag, or of
the tagged commit.

Subject: [PATCH 2/2] Reduce the first release's notes to "Initial release"

A first release has no earlier one to differ from, so a list of additions
and fixes says nothing a reader could act on.
