Especially notable end-user-visible changes with this release:

Improved PSX emulation.
GameBoy system type selection(though not completely implemented for the case of selecting CGB for a DMG game).
For NES emulation, improved iNES mapper 69 expansion sound emulation accuracy.
Default video settings that make more sense with modern desktop PC setups.
Experimental support for interpolation on only one axis without the use of a pixel shader, via new values for the .videoip setting.
New pixel shaders "autoip" and "autoipsharper", and a different algorithm for "ipsharper", "ipxnotysharper", and "ipynotxsharper".
New video stretch modes, "aspect_int" and "aspect_mult2".
Changed "video.glvsync" setting semantics to make forcibly disabling vsync simpler.
Added new setting "video.blit_timesync", which can be set to 0 to reduce video latency by up to 1 frame, though with caveats.
Support for screen rotation for all supported emulated systems, and remapped the rotate button from "F8" to "ALT + O".
Increased the maximum supported sound output rate to 1048576 Hz.
Win32 build now compiled with gcc 4.5.4-prerelease(with flag -mstackrealign for the time being to work around a memory alignment issue, which may hurt performance).
