I built this package to bring that pattern to Laravel.

Each old version gets a transformer class with two methods:

- upgradeRequest() — converts old payload to current format before your controller runs - downgradeResponse() — converts response back to old format before it leaves

The middleware chains them automatically across versions. Your controllers never change.

Supports 4 version detection strategies: URL prefix, header, query param, Accept header. Ships with deprecation headers (Sunset, Deprecation), artisan commands for changelog and audit.
