Security

[1.13.0]

Added

  • New option --http-retrieval-denylist. It can be used to avoid connecting to disallowed hosts.

Changed

  • upgrade to Boxo v0.30.0
  • upgrade go-ds-xxx packages to support go-datastore v0.8.2 query API
  • updated go-libp2p to v0.41.1

Fixed

  • Fix exporting of routing http client metrics: the endpoint will now include ipfs_routing_http_client_* metrics routing clients are used. See docs/metrics.md for more details.

Security

  • This release upgrades quic-go to v0.50.1. It contains a fix for a remote-triggered panic.

[1.12.0]

Added

  • HTTP block retrieval support: rainbow can now use Trustless HTTP Gateways to perform block retrievals in parallel to Bitswap.
    • This takes advantage of peers with /tls + /http multiaddrs (HTTPS is required).
    • You can enable HTTP retrievals with --http-retrieval-enable, and limit it to urls of specific hostnames with --http-retrieval-allowlist <hostname>.
    • You can also ignore provider records from certain peer IDs with --routing-ignore-providers <peerID> (for example to ignore peer IDs from bitswap endpoints of providers that offer HTTP).
    • NOTE: this feature works in the same way as Bitswap: known HTTP-peers receive optimistic block requests even for content that they are not announcing. See Boxo's CHANGELOG for more information.

[1.11.0]

Changed

  • The default DNSLink resolver for .eth TLD changed to https://dns.eth.limo/dns-query and .crypto one changed to https://resolver.unstoppable.io/dns-query #231
  • Upgrade to Boxo v0.28.0
  • Upgrade go-ds-pebble to v0.4.2 and pebble to v1.1.4
  • updated go-libp2p to v0.40.0
  • require minimum go version 1.24 in go.mod

[1.10.1]

Added

  • Add support for custom DNSLink resolvers (e.g. to support TLDs like .eth, .crypto). It is possible to set custom DoH resolvers by setting RAINBOW_DNSLINK_RESOLVERS with the same convention as Kubo's DNS.Resolvers ) #224

[1.10.0]

Changed

  • boxo v0.26.0
    • This has a number of significant updates including go-libp2p v0.38.1 and go-libp2p-kad-dht v0.28.1
  • Upgrade to latest nopfs v0.14.0

[v1.9.0]

Added

  • Added endpoints to show and purge connected peers #194
  • Added flags to configure bitswap/routing tuning params:
    • routing-max-requests
    • routing-max-providers
    • routing-max-timeout

Changed

  • boxo v0.25.0
  • go-libp2p-kad-dht v0.28.1
  • passing headers that require authorization but are not authorized now results in an HTTP 401 instead of ignoring those headers
  • Bitswap settings: Increased default content-discovery limits, with up to 100 in-flight requests.

[v1.8.3]

Changed

[v1.8.2]

Changed

  • updated go-libp2p to v0.37.0
  • require minimum go version 1.23.2 in go.mod

[v1.8.1]

Changed

[v1.8.0]

Added

  • Support implicit protocol filters from IPIP-484 and customizing them via --http-routers-filter-protocols. #173
  • Dedicated tracing docs.

[v1.7.0]

Added

  • Ability to specify the maximum blocksize that bitswap will replace WantHave with WantBlock responses, and to disable replacement when set to zero. #165
  • Support use and configuration of pebble as datastore. Pebble provides a high-performance alternative to badger. Options are available to configure key tuning parameters (pebble-* in rainbow --help).

[v1.6.0]

Changed

  • Updated Go in go.mod to 1.22
  • Updated dependencies

Fixed

  • a bug whereby FindPeer won't return results for peers behind NAT which only have /p2p-circuit multiaddrs go-libp2p-kad-dht#976

[v1.5.0]

Added

  • Simple end-to-end test to check that trustless-gateway-domains are set correctly. #151 #157
  • HTTP API to dynamically list logging subsystems and modify logging levels for subsystems. #156

Changed

Fixed

[v1.4.0]

Added

  • Tracing per request with auth header (see RAINBOW_TRACING_AUTH) or a fraction of requests (see RAINBOW_SAMPLING_FRACTION)
  • Debugging with Rainbow-No-Blockcache that is gated by the Authorization header and does not use the local block cache for the request

Changed

  • go-libp2p 0.35
  • boxo 0.21

Fixed

  • Added more buckets to the duration histogram metric to allow for tracking operations that take longer than 1 minute.
  • Release version included in --version output.

[v1.3.0]

Added

  • Now supports remote backends (using RAW block or CAR requests) via --remote-backends (RAINBOW_REMOTE_BACKENDS).
  • Added configurable libp2p listen addresses for the Bitswap host via the libp2p-listen-addrs flag and RAINBOW_LIBP2P_LISTEN_ADDRS environment variable

[v1.2.2]

Fixed

  • Rainbow no longer initializes Bitswap server by default, restoring behavior from v1.0.0.

[v1.2.1]

Fixed

  • Rainbow no longer provides announcements of blocks via Bitswap. This is not needed to provide blocks to peers with RAINBOW_PEERING_SHARED_CACHE.
  • Rainbow no longer keeps track of other peer's Bitswap wantlists. It will only reply if they have the block at the moment. This should reduce the processing and memory usage.

[v1.2.0]

Added

  • ✨ Now supports automatic peering with peers that have the same seed via --seed-peering (RAINBOW_SEED_PEERING). You can further read how this works in docs/environment-variables.md.

[v1.1.0]

Added

  • ✨ Now supports local cache sharing with peers provided via --peering (RAINBOW_PEERING). You can further read how this works in docs/environment-variables.md.

[v1.0.0]

Our first version. Check the README for all the information regarding 🌈 Rainbow.
