v0.18.0

What's Changed

Notable changes / breakages

• The HTTP retriever no longer sends car-scope along with dag-scope parameters. This parameter was renamed during the course of development of the Trustless Gateway specification and has been kept until now for backward compatibility.
• The daemon now returns a 502 error when no candidates are returned from the indexer, this is in line with a suggestion in the specification.
• Various types and utilities have been extracted to https://pkg.go.dev/github.com/ipld/go-trustless-utils, users of Lassie as a library will likely need to update some of the types and packages used. This includes the github.com/filecoin-project/lassie/pkg/verifiedcar package now being moved to https://pkg.go.dev/github.com/ipld/go-trustless-utils/traversal.
• Lassie now has a new bitswap concurrency variable: BitswapConcurrencyPerRetrieval: WithBitswapConcurrencyPerRetrieval() and WithBitswapConcurrency() for the library, and --bitswap-concurrency-per-retrieval and bitswap-concurrency for the CLI now control bitswap concurrency. There is one global maximum concurrency and a per-retrieval concurrency that can be set to determine how many blocks to attempt to fetch in parallel where possible.
• DeferredCarWriter has been extracted to https://pkg.go.dev/github.com/ipld/go-car/v2/storage/deferred
• The dups=[y|n] parameter in the Content-Type for an HTTP transfer is properly handled; what a server says it provides, Lassie will accept and handle accordingly.
• --ipni-endpoint now works on both daemon and fetch modes in the CLI.
