docs/changes held 26 per-feature change notes and their index,
written while each feature was built. They were working records, not
documentation: they cite internal milestone numbers and plan steps,
several describe designs that changed before they shipped (the nano
note's config schema and a proxy plugin that was never built), and
nothing in the code, the build or the other docs refers to them. New
notes stopped being added a while ago; the commit messages carry that
record now.
The directory leaves the tree in this commit. Its contents stay
reachable in history, and the files were kept outside the repository
before removal. No code, build or test changes.
