The update dialog (server and desktop) now reads changelog/index.json and renders title, intro and groups; the release workflow builds the GitHub Release body and name from changelog/<version>.md; oc-dev, the issue-intake agent, AGENTS.md and the changelog skill no longer point at the file. CHANGELOG.md stays as a legacy copy for installs up to 1.22.1, which fetch it for update notes. The generator refreshes it while it exists and never recreates it, so deleting it after 2026-09-19 retires it for good. Generated outputs hold released versions only, so editing unreleased.md never makes them stale: agents write that file and nothing else, and oc-dev create-release does the generation.

Release notes source
One file per release, plus unreleased.md for what has not shipped. At release time oc-dev create-release turns unreleased.md into <version>.md with today's date and renders packages/vscode/CHANGELOG.md (extension, shown by the Marketplace as is) and index.json (website and the app's update dialog) from the released files. Edit the files here; the generated ones are overwritten and hold released versions only, so editing unreleased.md never leaves them stale.

Optional intro paragraph shown above the groups.
## App
### New
- Something the user could not do before.
### Improvements
- Something they could do works better now.
### Fixes
- Something was broken; name the symptom.
### Misc
- Bundled tool versions, packaging, platform support, retirements.
## VS Code
### Fixes
- Only what the extension actually mounts. Written separately, on purpose.
Groups may appear in any order in a source file; the generator emits them as New, Improvements, Fixes, Misc and drops empty ones. A release without a ## VS Code section is absent from the extension changelog. Every release needs a title; unreleased.md carries only the title line in its front matter and gets version and date at release time.
bun run changelog:check validates every source file and fails when a generated file is behind the released sources; CI runs it. It writes nothing.
CHANGELOG.md at the repo root is legacy: app versions up to 1.22.1 fetch it from main for their update notes. It is refreshed while it exists and never recreated; delete it after 2026-09-19 and it is gone for good.
How to write the title and the bullets lives in .agents/skills/changelog-authoring/SKILL.md.
