Go-libp2p v0.22.0

[marten]

We’re happy to announce the v0.22.0 release of go-libp2p.

go-libp2p is a mono-repo now

This release finishes our long-term effort of consolidating repositories (#1556), turning go-libp2p into a mono-repo. In this release, we’ve moved the last 4 remaining repositories here:

• GitHub - libp2p/go-libp2p-resource-manager: An implementation of the libp2p network resource manager interface
• GitHub - libp2p/go-libp2p-peerstore: an object to manage sets of peers, their addresses and other metadata
• GitHub - libp2p/go-eventbus: a simple and fast eventbus for type-based local event delivery.
• GitHub - libp2p/go-libp2p-core: Interfaces and abstractions that make up go-libp2p

As with our last consolidation release (v0.20.0), this means that some import paths might have changed. The recommended way of updating is the following:

1. Run go get -u ./.... This will pull in updated dependencies, including updates for all the repositories listed above.
2. Run staticcheck ./.... All repositories listed above were deprecated, and staticcheck will generate errors when they are imported.

Other noteworthy changes

• When no Identity is passed to libp2p.New, we generate a private key for you. We now generate an Ed25519 key instead of a RSA key (#1576).
• AutoRelay now actively polls for new candidates, instead of expecting the application to continuously deliver new candidates (#1569).
