# 0.24.0 [unreleased]

- Update to `libp2p-core` `v0.39.0`.

- Rename types as per [discussion 2174].
  `RequestResponse` has been renamed to `Behaviour`.
  The `RequestResponse` prefix has been removed from various types like `RequestResponseEvent`.
  Users should prefer importing the request_response protocol as a module (`use libp2p::request_response;`),
  and refer to its types via `request_response::`. For example: `request_response::Behaviour` or `request_response::Event`.
  See [PR 3159].

- Update to `libp2p-swarm` `v0.42.0`.

- Always properly `close()` the substream after sending requests and
responses in the `InboundUpgrade` and `OutboundUpgrade`. Otherwise this is
left to `RequestResponseCodec::write_request` and `RequestResponseCodec::write_response`,
which can be a pitfall and lead to subtle problems (see e.g.
https://github.com/libp2p/rust-libp2p/pull/1606).

# 0.1.0

- Initial release.
