-These methods were deprecated because they can be used in a way which does not
-hold the channel reference alive long enough to receive the events.
+Type: Deprecation revoked
 
-Use [`diagnostics_channel.subscribe(name, onMessage)`][] or
-[`diagnostics_channel.unsubscribe(name, onMessage)`][] which does the same
-thing instead.
+These methods were deprecated because their use could leave the channel object
+vulnerable to being garbage-collected if not strongly referenced by the user.
+The deprecation was revoked because channel objects are now resistant to
+garbage collection when the channel has active subscribers.
