 - Update to `libp2p-swarm-derive` `v0.32.0`.
 
-- Remove type parameter from `PendingOutboundConnectionError` and `PendingInboundConnectionError`.
-  These two types are always used with `std::io::Error`. See [PR 3272].
-
 - Replace `SwarmBuilder::connection_event_buffer_size` with `SwarmBuilder::per_connection_event_buffer_size` .
   The configured value now applies _per_ connection.
   The default values remains 7.
   If you have previously set `connection_event_buffer_size` you should re-evaluate what a good size for a _per connection_ buffer is.
   See [PR 3188].
 
-- Add `PendingConnectionError::LocalPeerId` to differentiate wrong VS local peer ID errors. See [PR 3377].
-
-- Remove `PendingConnectionError:::IO` variant.
-  This was never constructed.
-  See [PR 3373].
-
 - Remove `DialError::ConnectionIo` variant.
   This was never constructed.
   See [PR 3374].
