# Rewrite 5
- 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
