CHANGELOG.md

CHANGELOG.md records the changes of each version, newest entry first. release.mjs reads it to commit, tag and push.
An entry is a ## x.y.z heading, a blank line, one summary line, a blank line, and the changes as - items.
The summary line is the commit message: a type prefix as in the git history (feature:, fix:, update:), then one sentence. It must not start with - or #.
An entry whose version is already tagged (git tag) is released and must not be changed. Changes after it go into a new entry above it.
Record every change you make in the newest untagged entry; when there is none, add one. Raise the patch version for fixes and the minor version for features.
Items describe what changed for the user, not the reasoning; reasons go to ADR.md.
Do not run release.mjs without -n; committing, tagging and pushing need the user's approval.
