# 0.30.1 [2021-04-21]
- Fix timely discovery of peers after listening on a new address.
[PR 2053](https://github.com/libp2p/rust-libp2p/pull/2053/)
# 0.30.0 [2021-04-13]
- Derive `Debug` and `Clone` for `MdnsConfig`.
- Update `libp2p-swarm`.
# 0.29.0 [2021-03-17]
- Introduce `MdnsConfig` with configurable TTL of discovered peer
records and configurable multicast query interval. The default
query interval is increased from 20 seconds to 5 minutes, to
significantly reduce bandwidth usage. To ensure timely peer
discovery in the majority of cases, a multicast query is
initiated whenever a change on a network interface is detected,
which includes MDNS initialisation at node startup. If necessary
the MDNS query interval can be reduced via the `MdnsConfig`.
The `MdnsService` has been removed from the public API, making
it compulsory that all uses occur through the `Mdns` `NetworkBehaviour`.
An `MdnsConfig` must now be given to `Mdns::new()`.
[PR 1977](https://github.com/libp2p/rust-libp2p/pull/1977).
- Update `libp2p-swarm`.
# 0.28.1 [2021-02-15]
- Update dependencies.
# 0.28.0 [2021-01-12]
- Update dependencies.
# 0.27.0 [2020-12-17]
- Update `libp2p-swarm` and `libp2p-core`.
# 0.26.0 [2020-12-08]
- Create multiple multicast response packets as required to avoid
hitting the limit of 9000 bytes per MDNS packet.
[PR 1877](https://github.com/libp2p/rust-libp2p/pull/1877).
- Detect interface changes and join the MDNS multicast
group on all interfaces as they become available.
[PR 1830](https://github.com/libp2p/rust-libp2p/pull/1830).
- Replace the use of macros for abstracting over `tokio`
and `async-std` with the use of `async-io`. As a result
there may now be an additional reactor thread running
called `async-io` when using `tokio`, with the futures
still being polled by the `tokio` runtime.
