April 2026 performance summary for laravel/framework: - Delivered Debounce-based Queued Job Execution to optimize background processing. Implemented a DebounceLock cache-based ownership model and the DebounceFor attribute to ensure only the most recent queued job with the same debounce identity executes, introducing last-dispatch-wins semantics and reducing redundant work across high-throughput queues. - Replaced previous Debounced middleware and ShouldBeDebounced interface with a streamlined attribute-driven approach, simplifying usage and improving maintainability. - Achieved deep integration with core queue flow: PendingDispatch, CallQueuedHandler, and transactional rollback logic to ensure correct ownership checks and safe execution even under failures. - Enhanced reliability and observability: introduced JobDebounced event, expanded test coverage, and stabilized behavior across the Beanstalkd and Redis drivers. - Refined lifecycle and TTL semantics: moved from lock-based debounce to a cache-key approach, with generous TTL for garbage collection and race-free supersession checks, reducing deadlock risk and improving correctness in delayed dispatch scenarios.
