Evolve API Platform APIs via deprecation (deprecationReason/sunset, RFC 8594/9745), the recommended alternative to versioning; plus path/header strategies.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Api Platform Versioning (Symfony) ## Use when - A field, operation, or resource is being renamed or removed and consumers need time to migrate. - Announcing a removal date to clients with `Sunset` and `Deprecation` headers. - Deciding between deprecation and parallel `/v1` and `/v2` surfaces. - A breaking representation change that deprecation and groups cannot express. ## Default workflow 1. Try deprecation first: set `deprecationReason` on the resource, the operation, or `#[ApiProperty]`. 2. Add `sunset:` with a date, and on v4 add `headers` carrying `Deprecation` (RFC 9745) and a `Link` with `rel="successor-version"`. 3. Before v4, emit those headers from a `KernelEvents::RESPONSE` listener. 4. Only if still breaking, expose parallel `uriTemplate` values (`/v1`, `/v2`) with distinct groups, or output DTOs with one provider per version. 5. Mark the old operation as deprecated in OpenAPI, document the changes per version, and test every active version. ## Guardrails - Prefer deprecation: path versioning is the fallback, not the default. - Always set a sunset date and keep at most 2 or 3 versions active. …

How to install
mdr add dev-toolings/superpowers-symfony/api-platform-versioning@sha256:5549c1901f05d255The line at the top of this page pins the label git:20261005.7b53095, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
