[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.
