- Added: EnableExplicit/DisableExplicit: variables must be declared with Define, Global, Protected, Shared or Static.
- Added: Defined(Name, Type) compiler function. Type can be #PB_Constant, #PB_Variable, #PB_Array, #PB_LinkedList, #PB_Structure, #PB_Interface
- Added: ReDim for single and multi-dimensionned arrays
- Added: Import/ImportC/EndImport to import functions and variables from external .lib
- Added: LinkedList and Arrays can now be passed as procedure parameters
- Added: PseudoTypes: p-ascii, p-unicode, and p-utf8
- Added: Assembler and Linker errors for CLI compiler are now directly displayed
- Added: OpenGL subsystem for multimedia applications
- Added: full alphachannel support for Sprite3D library (trough PNG and TIFF)
- Added: Subsystem() compiler directive to check if a subsystem is in use

- Added: 'Step over' and 'Step out' features to the debugger
- Added: Process library
- Added: Shared objects (.so) creation
