v0.18.0

We're happy to announce the v0.18.0 release of go-libp2p.

🛠 Breaking Changes

In this release, we're continuing our repo consolidation. We've moved the following repositories into go-libp2p:

• go-libp2p-autonat
• go-libp2p-discovery
• go-libp2p-connmgr
• go-addr-utils
• go-libp2p-netutil
• go-sockaddr

If you've been using functions from these repositories, please make sure to point those to go-libp2p.

🔦 Highlights

The main feature of v0.18.0 is the Resource Manager. The Resource Manager allows the configuration of (among others):

• the number of incoming / outgoing connections
• the number of incoming / outgoing streams
• the number of streams per protocol, and per service
• memory usage

For details on how this works, and how to change limits, refer to the README of the Resource Manager.

In this release, we've finished the transition from ipfs/go-log@v1 to ipfs/go-log@v2. One less dependency!
