## 0.24.1
- Deprecate `handler`, `codec` modules to make them private. See [PR 3847].
[PR 3847]: https://github.com/libp2p/rust-libp2p/pull/3847
## 0.24.0
- 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`.

## 0.1.1
- 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.
