Kubo changelog v0.24

v0.24.0

Overview

🔦 Highlights

Support for content blocking

This Kubo release ships with built-in content-blocking subsystem announced earlier this year. Content blocking is an opt-in decision made by the operator of ipfs daemon. The official build does not ship with any denylists.

Gateway: the root of the CARs are no longer meaningful

When requesting a CAR from the gateway, the root of the CAR might no longer be meaningful. By default, the CAR root will be the last resolvable segment of the path. However, in situations where the path cannot be resolved, such as when the path does not exist, a CAR will be sent with a root of bafkqaaa (empty CID). This CAR will contain all blocks necessary to validate that the path does not exist.

IPNS: improved publishing defaults

This release changes the default values used when publishing IPNS record via ipfs name publish command:

  • Default --lifetime increased from 24h to 48h to take full advantage of the increased expiration window of Amino DHT (go-libp2p-kad-dht#793)
  • Default --ttl increased from 1m to 1h to improve website caching and follow saner defaults present in similar systems like DNS (specs#371)

This change only impacts the implicit defaults, when mentioned parameters are omitted during publishing. Users are free to override the default if different value makes more sense for their use case.

IPNS: record TTL is used for caching

In this release, we've made significant improvements to IPNS caching.

Previously, the TTL value in IPNS records was not utilized, and the boxo/namesys library maintained a static one-minute resolution cache.

With this update, IPNS publishers gain more control over how long a valid IPNS record remains cached before checking an upstream routing system, such as Amino DHT, for updates. The TTL value in the IPNS record now serves as a hint for:

  • boxo/namesys: the internal cache, determining how long the IPNS resolution result is cached before asking upsteam routing systems for updates.
  • boxo/gateway: the Cache-Control HTTP header in responses to requests made for /ipns/name content paths.

These changes make it easier for rarely updated IPNS-hosted websites to be cached more efficiently and load faster in browser contexts.

Experimental Transport: WebRTC Direct

WebRTC Direct has now been introduced in go-libp2p v0.32.0. This transport protocol allows browser nodes to connect to other nodes without special configuration, such as TLS certificates. This can be useful for browsers that do not yet support WebTransport, for example.

Note that, at the moment, WebRTC Direct cannot be used to connect to a browser node to a node that is behind a NAT or firewall. This is being worked on go-libp2p#2009.
