 Ask the user to review, publish notes on the [Appwrite changelog](https://appwrite.io/changelog), generate specs if the API changed, and add request/response filters if needed.
 
+`APP_CACHE_BUSTER` is not a version number and does not track releases. It salts the response cache key in [`Request::cacheIdentifier()`](src/Appwrite/Utopia/Request.php) for the routes labelled `cache` (file preview, avatars). Bump it only when cached output would now be wrong — a changed image pipeline or new bundled avatar assets — since every bump orphans every entry and regenerates them.

 ### Self-hosted RC / final
 
 A release is not ready until a **fresh install** and an **upgrade from the previous stable** both work with realistic data. Previous baseline = highest stable semver tag lower than the target (ignore RC/beta/alpha; prefer `git ls-remote --tags origin`).

 **Upgrade:** install the previous stable image, seed broad data (empty values, long strings, relationships, mixed permissions), keep volumes, switch to the target image, run migrate. Migration must complete, be idempotent, and preserve seeded data through public API reads/writes.

 Do not approve an RC/final until both gates pass, metadata matches the target, and unintended public breaks have filters (or the owner documents the break on the changelog).
