- Several improvements to make the recompilers work with newer compilers and add some workarounds about clang confusing itself.
- Fix several variables being the wrong size in the recompiler.
- Support absolute 64 bit addressing. (DRC:64 bit error messages)
- Zero extend data in dynrec core for LLVM compilation/
- Reduce overhead of the Mac version with a lot. Results in a speed increase.
- Replace NV_PixelDataRange with the more common ARB_PixelBufferObject extension. Should help with output=opengl.

- Add patches to work better when called by WINE:
- support WINE style namemangling.
- allow Z: to be moved to a different drive.

- Fix expanddot not caring about the size of the inputbuffer.
- Some fixes for the debugger related to starting a program through debug.com.
- Bring OS/2 port code up to date.
- Reduce the amount of warning when compiling with quite a bit.
- Allow 15/26/32 bits input to the opengl output.
- Add cmd-q as exit key for macs.
- Fix icon and titlebar on very old setups.
