# 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`.
