⚠️ Breaking changes

Require that heatmap-color use expressions instead of stop functions #5624
Remove support for validating and migrating v6 styles
Remove support for validating v7 styles #5604

✨ Features and improvements

Improve label collision detection #5150
- Labels from different sources will now collide with each other
- Collisions caused by rotation and pitch are now smoothly transitioned with a fade
- Improved algorithm for fewer erroneous collisions, denser label placement, and greater label stability during rotation
Add sqrt expression #5493
