+# go-libp2p v0.29.0 update with smart dialing
+
+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).  This release includes smart dialing, which is a prioritization algorithm that will try to rank addresses and protocols rather than attempting all options in parallel.  Anecdotally, we have observed [Kubo nodes make 30% less dials](https://github.com/libp2p/go-libp2p/issues/2326#issuecomment-1644332863) with no to low latency impact.
+
+This includes a breaking change to `ipfs id` and some of the `ipfs swarm` commands.  We no longer report `ProtocolVersion`.  This used to be hardcoded as `ipfs/0.1.0` and sent to other peers but was not providing any distinguishing value.  See [libp2p/go-libp2p#2294](https://github.com/libp2p/go-libp2p/issues/2294) for more information.
