#🛠 BREAKING CHANGES

#Removed mdns_legacy implementation

The modern DNS-SD compatible zeroconf implementation (based on this specification) has been running next to the mdns_legacy for a while (since v0.11). During this transitional period Kubo nodes were sending twice as many LAN packets, which ends with this release: we've removed the legacy implementation.

#🔦 Highlights

#🛣️ Delegated Routing

Content routing is the a term used to describe the problem of finding providers for a given piece of content. If you have a hash, or CID of some data, how do you find who has it? In IPFS, until now, only a DHT was used as a decentralized answer to content routing. Now, content routing can be handled by clients implementing the Reframe protocol.

Example configuration usage using the Filecoin Network Indexer:

ipfs config Routing.Routers.CidContact --json '{
  "Type": "reframe",
  "Parameters": {
    "Endpoint": "https://cid.contact/reframe"
  }
}'

#👥 Rename to Kubo

We've renamed Go-IPFS to Kubo (details).

Published artifacts use kubo now, and are available at:

• https://dist.ipfs.tech/kubo/
• https://hub.docker.com/r/ipfs/kubo/

To minimize the impact on infrastructure that autoupdates on a new release, the same binaries are still published under the old name at:

• https://dist.ipfs.tech/go-ipfs/
• https://hub.docker.com/r/ipfs/go-ipfs/

The libp2p identify useragent of Kubo has also been changed from go-ipfs to kubo.

#🎒 ipfs repo migrate

This new command allows the you to run the repo migration without starting the daemon.

See ipfs repo migrate --help for more info.

#🚀 Emoji support in Multibase

Kubo now supports base256emoji encoding in all Multibase contexts. Use it for testing Unicode support, as visual aid while explaining Multiformats, or just for fun:

$ echo -n "test" | ipfs multibase encode -b base256emoji -
🚀😈✋🌈😈

$ echo -n "🚀😈✋🌈😈" | ipfs multibase decode -
test

$ ipfs cid format -v 1 -b base256emoji bafybeigdyrzt5sfp7udm7hu76uh7y26nf3efuylqabf3oclgtqy55fbzdi
