# 0.22.0 [2021-02-15] - Rename the crate to `libp2p-swarm-derive`. # 0.21.0 [2020-11-25] - Update for compatibility with `libp2p-swarm-0.25`. # 0.20.2 [2020-07-28] - Generate fully-qualified method name for `poll` to avoid ambiguity. [PR 1681](https://github.com/libp2p/rust-libp2p/pull/1681). # 0.20.1 [2020-07-08] - Allow users to opt out of the `NetworkBehaviourEventProcess` mechanism through `#[behaviour(event_process = false)]`. This is useful if users want to process all events while polling the swarm through `SwarmEvent::Behaviour`.
