-
-
-### Chores
-
-* remove peer-info usage on topology ([#42](https://github.com/libp2p/js-interfaces/issues/42)) ([79a7843](https://github.com/libp2p/js-interfaces/commit/79a7843))
-* update content and peer routing interfaces removing peer-info ([#43](https://github.com/libp2p/js-interfaces/issues/43)) ([d2032e6](https://github.com/libp2p/js-interfaces/commit/d2032e6))
-
-
-### Features
-
-* peer-discovery not using peer-info ([5792b13](https://github.com/libp2p/js-interfaces/commit/5792b13))
-
-
-### BREAKING CHANGES
-
-* topology api now uses peer-id instead of peer-info
-* content-routing and peer-routing APIs return an object with relevant properties instead of peer-info
-* peer-discovery emits object with id and multiaddrs properties
