AI translates the explanation and quiz text while preserving code and answer scoring.

API versioning strategies in Laravel include URL prefixes (Route::prefix('v1')->group(...)), header-based versioning (Accept: application/vnd.myapp.v2+json), or versioned API Resource classes producing different response shapes per version. Deprecation should be communicated via response headers (Deprecation, Sunset) well before removing an old version. Keeping versioned controllers/resources thin and delegating shared logic to services avoids duplicating business logic across versions.
