✅ 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 to see if there are any out-of-date deps that look important.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.
  • Make sure local tests are passing.
• Stage 1 - Upstream Testing
  • Create testing branches in lotus & go-ipfs with the new go-libp2p release and run CI/tests. Many upstream projects are tested in CI, but lotus & go-ipfs are not.
    • filecoin-project/lotus
    • ipfs/go-ipfs
  • (someday) Run upstream testground tests. Unfortunately, this is too time consuming at the moment.
    • (someday) Run bitswap testground tests.
    • (someday) Run DHT testground tests.
• Stage 2 - Infrastructure Testing
  • How: Using the testing branches created above, work with the infrastructure team to deploy the new libp2p versions to our infrastructure.
  • Where:
    • A go-ipfs gateway.
      • Deploy
      • Analyze
        • Look at pprof profile dumps, especially CPU profiles and heap allocation profiles, noting any significant changes.
    • A go-ipfs bootstrapper.
      • Deploy
      • Analyze
        • Look at pprof profile dumps, especially CPU profiles and heap allocation profiles, noting any significant changes.
        • Check peers (e.g., ipfs swarm peers) to make sure we're connecting to peers on all transports.
        • Check advertised addresses and protocols (e.g., ipfs id) to make sure they're sane.
• Stage 3 - Release
  • Tag the release on master.
  • 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.
• Stage 4 - Update Upstream
  • Update the examples to the final release. Pay special attention to deprecated repos
  • Update the upstream testing branches to the final release and create PRs.
    • filecoin-project/lotus
    • ipfs/go-bitswap
    • ipfs/go-ipfs
    • libp2p/go-libp2p-kad-dht
    • libp2p/go-libp2p-pubsub
    • libp2p/go-libp2p-daemon
• Make required changes to the release process.
