# Rewrite 5

Browse Source 
- Move Libraries Source into pd directory and give them all their own CMakeLists.txt
- Partial rewrite core (color, autogenerated vec), lithium (now uses UNIQUE PTR for Commands), UI7
- Use MenuV2 as new standart in UI7
- Implementz ViewPort Pre alpha to UI7
- Add Line Drawing to DrawList (not Working)
- Implement a Complete new drievrs API (static Drivers)
- NO SUPPORT FOR SHARED LIBRARY BUILDS IN VERSION 5 YET
- Add Tools to Autogenerate Headers and Stuff
