v2.2.0

Features

• Open sources only — openSourcesOnly: true on search excludes the paywalled source group (paywall/paywalled_sources) for every kind and aggregate, both as a flat filter and inside an advanced query ($not); the default still searches all sources. A note under the result says the exclusion was applied
• Source group lookup — suggest(type: "sourceGroups") lists the curated source groups so options.sourceGroupUri and ignoreSourceGroupUri can be resolved by name; it requests 100 rows because the catalog exceeds the API's default page of 20

Improvements

• Toolchain — Development dependencies move to eslint 10, vitest 5, TypeScript 6.0 and esbuild 0.28; no change to the published package
