The 5.6 release blog post documented RegisteredController#eventRecorder(), which no longer exists: the recorder is now stateless and shared, with the reconciliation Context passed per call (EventRecorder#record(EventRecord, Context)), and it can only record events about the primary resource.

This replaces that section with how to plug in a custom EventRecorder via ConfigurationServiceOverrider#withEventRecorder and how it relates to context.eventRecorder().

Checked the rest of the docs (docs/content/en/docs): no other references to the removed API; the josdk.events.cluster-scoped-namespace and RBAC notes in configuration.md are still accurate.

Summary by CodeRabbit

• Documentation
  • Added guidance for configuring a custom event recorder, including its sharing and thread-safety requirements.
  • Clarified that the recorder receives reconciliation context and replaces the default recorder when configured.
  • Removed guidance on recording events outside reconciliation or for non-primary resources.

Walkthrough

The v5.6 release notes now explain how to configure a custom EventRecorder, describe its shared, stateless, thread-safe contract, and state that the default is a per-controller DefaultEventRecorder.

Changes: EventRecorder release notes

Layer / File(s)	Summary
Custom recorder configuration and contract docs/content/en/blog/releases/v5-6-release.md	The notes describe supplying a custom EventRecorder through withEventRecorder, its shared stateless and thread-safe contract, and the default per-controller recorder. They remove guidance about recording events outside reconciliation or for non-primary resources.

Merge Risk: Low · up to a7d3c

The release note should say that custom recorders must handle their own recording failures. This is a small documentation fix, and the merge risk is low.

State the error-handling requirement for custom recorders.

The SDK does not enforce best-effort recording around a custom recorder. If its sink throws, the exception can fail reconciliation.

Suggested fix

 bound to that context. Without a custom recorder, every controller records its events through a
 `DefaultEventRecorder` of its own.
 
+Custom recorders must log and swallow recording failures, including through their context-bound view.

 Two properties are worth calling out:
