Laravel 13.6.0 ships several notable features. The headline addition is debounceable queued jobs via the #[DebounceFor] attribute — when the same job is dispatched multiple times within a time window, only the last dispatch executes. A maxWait parameter prevents indefinite deferral. The release also adds JSON response support for the built-in /up health route (useful for API-only apps and load balancers), a new JsonFormatter for structured logging compatible with ELK/Datadog, and Cloudflare Email Service integration. Testing improvements include multi-record assertions for assertDatabaseHas/assertDatabaseMissing, and the hasAttached factory method now accepts arrays of pivot arrays. Additional fixes cover validation rules, enum support in BroadcastManager, PasswordBrokerManager, and NotificationChannelManager, plus SQS named credential providers.
