libp2p-swarm-derive 0.34.2

## 0.34.2

- Generate code for `libp2p-swarm`'s `FromSwarm::NewExternalAddrOfPeer` enum variant.
  See [PR 4371](https://github.com/libp2p/rust-libp2p/pull/4371).

- Restore support for generic constraints on behaviours combined with `out_event` generated by `NetworkBehaviour` where no where clause is used.
  See [PR 5003](https://github.com/libp2p/rust-libp2p/pull/5003).

## 0.34.1

  See [PR 4825](https://github.com/libp2p/rust-libp2p/pull/4825).

## 0.34.0

- Adapt to interface changes in `libp2p-swarm`.
  See [PR 4706](https://github.com/libp2p/rust-libp2p/pull/4076).
- Remove supported for deprecated `#[behaviour(out_event = "...")]`.
  To same functionality is available using `#[behaviour(to_swarm = "...")]`
  See [PR 4737](https://github.com/libp2p/rust-libp2p/pull/4737).

## 0.33.0

## 0.32.0

- Fix `NetworkBehaviour` Derive macro for generic types when `out_event` was not provided. Previously the enum generated
  didn't have the `NetworkBehaviour` impl constraints whilst using the generics for `<Generic>::OutEvent`.
  See [PR 3393].

- Replace `NetworkBehaviour` Derive macro deprecated `inject_*` method implementations
  with the new `on_swarm_event` and `on_connection_handler_event`.

## 0.31.0

- Add `prelude` configuration option.
  The derive-macro generates code that needs to refer to various symbols. See [PR 3055].

[PR 3090]: https://github.com/libp2p/rust-libp2p/pull/3090

## 0.30.1

- Fix an issue where the derive would generate bad code if the type parameters between the behaviour and a custom
  out event differed. See [PR 2907].
- Fix an issue where the derive would generate incorrect code depending on available imports. See [PR 2921].

## 0.23.0 [2021-04-14]

- Extend `NetworkBehaviour` callbacks, more concretely introducing new `fn
  inject_new_listener` and `fn inject_expired_external_addr` and have `fn
  inject_{new,expired}_listen_addr` provide a `ListenerId` [PR

## 0.20.1 [2020-07-08]

- Allow users to opt out of the `NetworkBehaviourEventProcess`
mechanism through `#[behaviour(event_process = false)]`. This is
useful if users want to process all events while polling the
swarm through `SwarmEvent::Behaviour`.
