- [ ] #3384
- [ ] #3386
- [ ] #3407

## 🔦 Highlights

#3384 separates out go-libp2p/core as a separate module. This allows libraries to build against the core interfaces rather than a specific version of go-libp2p.

#3386 shows an outline of how customize a go-libp2p host, and only bring the parts one needs.

## ✅ Release Checklist

- [ ] **Stage 0 - Finishing Touches**
- [ ] Go through relevant libp2p repos looking for unreleased changes that should make it into the release. If you find any, cut releases.
- [ ] Run `go get -u ./...` to see if there are any out-of-date deps that look important. If there are, bubble them. Try to avoid _directly_ updating indirect deps in go-libp2p's `go.mod` when possible.
- [ ] **Stage 1 - Release**
- [ ] Publish the release through the GitHub UI, adding the release notes. Some users rely on this to receive notifications of new releases.
- [ ] Announce the release on the [discuss.libp2p.io](https://discuss.libp2p.io).
- [ ] **Stage 2 - Update Upstream**
- [ ] Update the examples to the final release
- [ ] Update the upstream dependencies to the final release and create PRs.
