What's New in CDL Permit Prep
1.0.2
August 17, 2026
Clearer study feedback. After each answer the app now says what actually happens next — whether you will see it again sooner or later — instead of naming an internal scheduling step. Your progress shows as a mastery level rather than a box number: on the study screen, in the deck browser, and in your stats.
