Note
Low Risk
Generated data-only update with no application logic changes; fingerprint scoring may shift slightly for some scripts until consumers pick up the new weights.
Overview
Automated Tracker Radar build output from Jenkins refreshes regional release statistics and API fingerprint weights used when scoring scripts for fingerprinting behavior.
Regional
releasestats.txt(AU, CA, CH, DE, FR, GB, NL, NO, US) now report slightly lower domain and entity counts than the previous snapshot—for example US moves from ~22.4k domains / ~2.6k entities to ~21.9k / ~2.6k.api_fingerprint_weights.jsonis regenerated from the latest crawl: per-API weights shift across the board (suspicious vs non-suspicious call ratios). Several touch/input-related APIs andNavigator.prototype.keyboardnow share a much higher weight (~7237 vs ~5524 previously), which will change how fingerprint scores aggregate for resources that use those APIs.Reviewed by Cursor Bugbot for commit 6b27f37.
