Version 2.1.2 - November 23, 2025¶

🎨 Improvements

We have now added an Advanced Search on the Exercise List page allowing users to find exercises based on sheet music patterns.

🐛 Bug Fixes

Reports page fixed
JS file not loading - Fixed template path ('js/...' not '/js/...') and view pointing to wrong template
Variant selection - Now selects correct voice type variant when user changes voice type
Range filtering order - Deduplicates first, then applies range filter (so variants aren't filtered out before selection)
Edge/Stretch modes - Always applies range filter for edge/stretch training
Comfort + voice type - Skips range filter when exploring different voice types in comfort mode
Applied to both pages - category-exercises and category-list use same logic
No-profile CTA - Users without range test now see a nice prompt to take the test

🎨 Improvements

Personalized Exercise Filtering

Added three-tier vocal range filtering: Comfort Zone (within range), Edge Training (1-3 semitones beyond), and Stretching (3-6 semitones beyond)
Exercises are now filtered based on user's tested vocal range across all carousels (YouTube Songs, Pro Backing, Skills,Categories)
Smart variant selection automatically shows the best exercise variant for the user's voice type

New "Choose Exercise Range" modal with visual vertical range bar
