official beta plugins packageが更新されてるね。

[Plugins as of 30th of december 2009]
- SSSPSX pad plugin, updated to 1.7, is included again. Works with savestates now.
- GSdx now has some hacks in place, that might fix common upscale glitches.
- GSdx also has a new upscale method called Scaling. X2 scaling works best.

All the usual small tweaks and fixes are in here as well, of course
