What's New in This Version (release notes for build 9) • New free trial: 20 assessments over 14 days to get you started. • Purchase credit packs anytime — purchased credits never expire. • Improved accuracy of the dilation-velocity (ADV) metric: now shows "N/A" when there's no measurable re-dilation, instead of a misleading 0.0. • Stability and reliability improvements.
