 **TODO**: add links to IPIP https://github.com/ipfs/specs/issues/376
 
+# go-libp2p v0.29.0 update
+
+We updated from [go-libp2p](https://github.com/libp2p/go-libp2p) [v0.27.7](https://github.com/libp2p/go-libp2p/releases/tag/v0.27.7) to [v0.29.0](https://github.com/libp2p/go-libp2p/releases/tag/v0.29.0).
+
+The main intresting new feature is smart dialling, this is a prioritisation algorithm that will try to rank addresses and protocols.
+So when we are contacting one peer we aren't firing ~4 connections at attempts in parallel anymore.
+
+This includes a breaking change to `ipfs id` and some of the `ipfs swarm` commands, we do not report `ProtocolVersion` anymore.
+
+This used to be harcoded `ipfs/0.1.0` and sent to other peers but never did anything intresting.
