Added

• key field to ClientIssue in ClientSample — identifier of the related issue or resolution when one is provided.
• Documentation on IceCandidatePairStats.state, and source comments recording which RTCStatsIceCandidatePairState symbols are no longer in the W3C spec: new (never standardised) and cancelled (removed after w3c/webrtc-stats#66; last published in the 2016-12-14 Working Draft). Both symbols are retained for backward compatibility — no field or enum value was removed, so the wire format is unchanged.

Wire-format warning. ClientIssue field numbers shift because protobuf numbering follows sorted field order: payload moves 2 → 3 and timestamp 3 → 4. A decoder built against 3.2.0 will misread these. See docs/GENERATOR.md.

Changed

• The generator was rewritten in TypeScript (src/, run with npm run generate). The legacy index.js and its root-level helpers were removed. Generated TypeScript, Avro and protobuf output is byte-identical to the previous implementation.
• schemaVersion is now exported from the ClientSample module only. It was previously emitted by every generated module, which made src/index.ts re-export the same name twice and broke npm-samples-lib’s build (TS2308). The package still exports schemaVersion from its entry point.
• Generated Markdown no longer runs a section heading onto the end of the preceding table row, and no longer prints undefined for enum fields that have no description.
• All packages moved to TypeScript 7 with "module": "nodenext". Emit is still CommonJS; published entry points are unchanged.
• Dependencies refreshed: avro-js 1.12.1, @bufbuild/buf 1.72.0, @bufbuild/protobuf and @bufbuild/protoc-gen-es 2.13.0. Removed argparse, json-schema-to-markdown, protobufjs and typedoc, none of which were used.

Fixed

• @observertc/samples-decoder could not be imported. ClientSampleDecoder imported fromBinary from @bufbuild/protobuf/dist/cjs/from-binary, a path that stopped existing in protobuf-es v2; requiring the package threw ERR_PACKAGE_PATH_NOT_EXPORTED. It now imports from the package root.
