## 0.42.2
- Do not implicitly dial a peer upon `identify::Behaviour::push`.
Previously, we would dial each peer in the provided list.
Now, we skip peers that we are not connected to.
See [PR 3843].
[PR 3843]: https://github.com/libp2p/rust-libp2p/pull/3843
## 0.42.1
- Migrate from `prost` to `quick-protobuf`. This removes `protoc` dependency. See [PR 3312].
[PR 3312]: https://github.com/libp2p/rust-libp2p/pull/3312
## 0.42.0
- Update to `libp2p-core` `v0.39.0`.
- Move I/O from `Behaviour` to `Handler`. Handle `Behaviour`'s Identify and Push requests independently by incoming order,
previously Push requests were prioritized. see [PR 3208].
- Update to `libp2p-swarm` `v0.42.0`.
- Don't close the stream when reading the identify info in `protocol::recv`. See [PR 3344].

See [PR 3011].
- Replace `Handler`'s `ConnectionHandler` implemention `inject_*` methods with the new `on_*` methods.
See [PR 3085].
- Update `rust-version` to reflect the actual MSRV: 1.62.0. See [PR 3090].

## 0.40.0
- Update dependencies.
- Rename types as per [discussion 2174].
`Identify` has been renamed to `Behaviour`.
The `Identify` prefix has been removed from various types like `IdentifyEvent`.
Users should prefer importing the identify protocol as a module (`use libp2p::identify;`),
and refer to its types via `identify::`. For example: `identify::Behaviour` or `identify::Event`.
