Version 1.1.1
Patch ReleaseSep 5, 2025
Highlights
- Fixed edge animation and copy/paste functionality
- Resolved TypeScript compilation errors
- Improved clipboard operation reliability
Bug Fixes
- • Fixed edge animation for connected nodes - Edges now properly animate when their connected nodes are selected via individual selection, Ctrl+click multi-select, or box selection
