## 0.43.1
- Handle partial push messages.
Previously, push messages with partial information were ignored.
See [PR 4495].
[PR 4495]: https://github.com/libp2p/rust-libp2p/pull/4495
## 0.43.0
- Observed addresses (aka. external address candidates) of the local node, reported by a remote node via `libp2p-identify`, are no longer automatically considered confirmed external addresses, in other words they are no longer trusted by default.
Instead users need to confirm the reported observed address either manually, or by using `libp2p-autonat`.
In trusted environments users can simply extract observed addresses from a `libp2p-identify::Event::Received { info: libp2p_identify::Info { observed_addr }}` and confirm them via `Swarm::add_external_address`.
See [PR 3954] and [PR 4052].
- Remove deprecated `Identify` prefixed symbols. See [PR 3698].
- Raise MSRV to 1.65.
See [PR 3715].
- Reduce the initial delay before running the identify protocol to 0 and make the option deprecated.
See [PR 3545].
- Fix aborting the answering of an identify request in rare situations.
See [PR 3876].
- Actively push changes in listen protocols to remote.
See [PR 3980].

## 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.

## 0.42.0
- Update to `libp2p-core` `v0.39.0`.

See [PR 3085].

## 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`.
