Some checks failed
Go / build-and-release (push) Has been cancelled
Privileged events are now filtered based on ACL mode, allowing open access when ACL is "none." Added tests to verify behavior for different ACL modes, ensuring unauthorized and unauthenticated users can only access privileged events when explicitly permitted. Version bumped to v0.34.2.
