# 0.29.0 [unreleased]

- 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 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.
