-- Add new `on_swarm_event` method to `NetworkBehaviour` that accepts a `FromSwarm` enum and update
-  `inject_*` methods to call `on_swarm_event` with the respective `FromSwarm` variant and deprecate
-  `inject_*`.
-  To migrate, users should replace the `NetworkBehaviour::inject_*` calls with a single
-  implementation of `NetworkBehaviour::on_swarm_event` treating each `FromSwarm` variant in
-  the same way its corresponding `inject_*` call was treated.
-  See [PR 3011].
-
-- Add new `on_connection_handler_event` method with the same signature as `inject_event`, make the
-  default implementation of `inject_event` call `on_connection_handler_event` and deprecate it.
-  To migrate, users should replace the `NetworkBehaviour::inject_event` calls
-  with `NetworkBehaviour::on_connection_handler_event`.
