+**Issue #59 Resolved**: Comprehensive animation system with 30+ easing functions
+- Property-based animations for all UI classes (Frame, Caption, Sprite, Grid, Entity)
+- Individual color component animation (r/g/b/a)
+- Sprite sequence animation and text typewriter effects
+- Pure C++ execution without Python callbacks
+- Delta animation support for relative values

+### 2025-01-03: Major Stability Update
 **Major Cleanup**: Removed deprecated registerPyAction system (-180 lines)
 **Bug Fixes**: 12 critical issues including Grid segfault, Issue #78 (middle click), Entity setters
 **New Features**: Entity.index() (#73), EntityCollection.extend() (#27), Sprite validation (#33)
