# Changes -> 0.5.1

- 3ds
  - Remove Gfx values that are present in Backend Tamplate
  - Move to default Palladium Namespace
  - Set the Input Flags
- Desktop
  - Move to PD Namespace
  - Comment out old keyboard stuff
  - HidDriver needs a rewrite but is functional enough
- Core
  - Add u128 class (only used in input driver so far
- Drivers (Core)
  - Move Gfx to PD namespace
  - Move Vertex/Index Pos and Projection Mtx to Gfx template
  - Add Keyboard support with u128 to Hid
  - Add a Update func if no hiddriver is specified (to prevent crashes when requestign inputs)
- Image
   - Add RGBA -> BGRA support (used in windows bitmaps iirc)
- Lithium
  - Add Vertex/Index counters to drawlist
  - Add a LoadTTF from Mem func and let the loadfile func use PD::IO::LoadFile2Mem (looks cleaner)
  - Add LoadDefaultFont (which loads one of the integrated fonts if the PD_LI_INCLUDE_FONTS flag was passed on palaldium build) !!! Note that there are no fonts integrated yet due to i dont know how to handle licensing...
- UI7
  - Add MouseLeft support to Input handler
  - Use xy coords of the Viewport to create Menus inside it
  - Get num of Vertices/Indices out of FinalDrawList
  - Add some Palladium Info to metrics Menu
  - Readd Compiler string
- pdfm
  - New tool that creates fonts.cpp/fonts.hpp
