# 0.15.0
- Rename types as per [discussion 2174].
`Relay` has been renamed to `Behaviour`.
The `Relay`, and `Client` prefixes have been removed from various types like `ClientTransport`.
the `v2` namespace has also been removed, users should prefer importing the relay protocol as a module (`use libp2p::relay;`),
and refer to its types via `relay::`. For example: `relay::Behaviour` or `relay::client::Behaviour`.
See [PR 3238].
- Update to `libp2p-core` `v0.39.0`.
- Update to `libp2p-swarm` `v0.42.0`.
