WinUAE v2.3.3 Beta 4 is released. WinUAE is the commodore amiga emulator for Windows. WinUAE is a mostly complete software emulation of the hardware of the Commodore Amiga 500/1000/2000. A Commodore Amiga, for those who don’t know, is a 16/32 bit computer system based on the Motorola 680×0 CPU and a few specially designed custom chips that provide very good graphics and sound capabilities. Its first incarnation, the A1000, appeared in 1985, followed by the highly successful A500 and A2000 models. WinUAE is a port of the originally written for Unixish systems UAE; but over time, it seems the Windows port, WinUAE has become the best version available on any platform. WinUAE is free software: you are welcome to distribute copies of it and/or modify it, under certain conditions. There is no warranty of any kind for UAE. For more details concerning these issues, please read the GNU General Public License, which describes the terms under which WinUAE is distributed.

WinUAE v2.3.3 Beta 4 changelog:
- rawinput was not enabled properly in all situations (mainly affected -rawhid parameter)
- write log message if D3D command pipeline flush fails or is not supported (tearing in new vsync mode)
- added win32.gui_page= configuration entry, selects default panel when GUI opens
- magic mouse in fullwindow mode only uncaptures if mouse would move to another monitor
- quickstart mode now sets sound mode to "disabled but emulated" if it was "disabled", previously it was always set to "emulated".
- CD/CD image switching on the fly was unreliable (different problem than b2 fix)
- optimization that detects if sprite changed has not been working for ages
- sprites above or below bitplane area and AGA border sprite bit set caused graphics garbage around the mouse cursor in some situations.
- possible fix for autoresolution aspect ratio problems when filter aspect ratio setting is enabled
- removed default scroll lock -> inhibit screen updates key mapping
- AROS ROM updated

Remaining new vsync updates coming later...
