Release v3.4.6: fix duplicate PerformanceMetricsSubscriber registration.
Changelog
Fixed
- PerformanceMetricsSubscriber – Removed duplicate kernel event registration caused by combining
EventSubscriberInterface/getSubscribedEvents()with#[AsEventListener]on the same methods. Registration is now only viaEventSubscriberInterface(priorities unchanged:kernel.request31,kernel.terminate-1024). Hosts that forcedautoconfigure: falseto avoid double metrics can drop that override after upgrading.
