+### Features
+
+* gossipsub as default pubsub ([#2298](https://github.com/ipfs/js-ipfs/issues/2298)) ([902e045](https://github.com/ipfs/js-ipfs/commit/902e045))

+### BREAKING CHANGES
+
+* The default pubsub implementation has changed from floodsub to [gossipsub](https://github.com/ChainSafe/gossipsub-js). Additionally, to enable pubsub programmatically set `pubsub.enabled: true` instead of `EXPERIMENTAL.pubsub: true` or via the CLI pass `--enable-pubsub` instead of `--enable-pubsub-experiment` to `jsipfs daemon`.
