v0.13.0

Changed

• Removed If-None-Match test that sent bare CID as weak ETag (W/"<CID>") for directory listings. Matching a bare CID against a DirIndex-* ETag is not a spec requirement, just an optimization specific to boxo/gateway. Test moved to ipfs/boxo#1129. #261
• BREAKING: Range request tests (TestGatewayUnixFSFileRanges) moved to a new path-range-gateway spec. Gateways that do not support HTTP Range requests can now skip them with --specs -path-range-gateway. Multi-range response detection via side-effect was replaced by AnyOf that accepts both single-range and multipart responses. #258

Fixed

• HeaderBuilder.Clone() was copying Key_ into Value_, silently weakening response header assertions in cloned test cases (e.g. range request and CAR helpers). #280
• Removed X-Content-Type-Options: nosniff assertion from dag-json and dag-cbor response tests in TestNativeDag. The spec only requires this header for application/vnd.ipld.car and application/vnd.ipld.raw responses. #282
• CheckNot error messages now include a human-readable description of the negated check instead of printing Go pointer addresses (e.g. not(contains 'nosniff') instead of &{0x140001b3710}). #282
• Removed Content-Type request header from range test helpers. GET requests should not include Content-Type per RFC 7231 section 3.1.1.5, as it describes message body payload. #282
• JSON report now uses suite_pass/suite_fail actions for the overall test suite result, making it easier to distinguish from individual test pass/fail events. #250
• JSON report (--json-output) is now streamed as tests run instead of being generated after the suite finishes. Results appear in the file incrementally, and partial output is preserved if the process is interrupted. #249
