+### Features
+
+* pubsub: add global signature policy ([#66](https://github.com/libp2p/js-interfaces/issues/66)) ([946b046](https://github.com/libp2p/js-interfaces/commit/946b046))
+* update pubsub getMsgId return type to Uint8Array ([#65](https://github.com/libp2p/js-interfaces/issues/65)) ([e148443](https://github.com/libp2p/js-interfaces/commit/e148443))
+

+### BREAKING CHANGES
+
+* `signMessages` and `strictSigning` pubsub configuration options replaced
+with a `globalSignaturePolicy` option
+* new getMsgId return type is not backwards compatible with prior `string`
+return type.

 The interface aims to specify a common interface that all pubsub router implementation should follow. A pubsub router implementation should extend the [EventEmitter](https://nodejs.org/api/events.html#events_class_eventemitter). When peers receive pubsub messages, these messages will be emitted by the event emitter where the `eventName` will be the `topic` associated with the message.
