  • Add @fingerprintjs/fingerprintjs dependency for browser-based fingerprinting
  • Enhanced fingerprints now use deterministic format: fp-{hash} (no random suffix)
  • Legacy fingerprints keep random suffix for collision avoidance: legacy-{hash}-{suffix}
  • Update analytics to properly detect both fingerprint formats
  • Add comprehensive integration tests for both fingerprint types
  • Enhanced fingerprints provide better uniqueness through browser signals
  • Maintain backward compatibility with existing legacy fingerprints
