Kubo v0.40.0-rc1 is out!

This release candidate focuses on content addressing consistency, gateway spec compliance, and reliability. Please help us test before the final release.

Highlights

  • Same CID everywhere (IPIP-499) – CIDv0 and CIDv1 UnixFS profiles that produce identical CIDs across IPFS implementations
  • Cancelled ipfs add cleans up after itself – no more orphan blocks after Ctrl+C
  • Accelerated DHT Client and Provide Sweep now work together – content providing waits for the initial FullRT DHT crawl, so pins are properly distributed if you use both
  • Go 1.26 – lower memory usage and fewer GC pauses (Green Tea GC)
  • Gateway spec updates (IPIP-523, IPIP-524), PubSub flood resistance, ipfs swarm addrs autonat, WebUI v4.11.0

See the full changelog for all changes, including new diagnostic commands, WebUI v4.11.0, Badger v1 deprecation, and more.
