Lightspark 0.4.5 Flash Player Released
Besides dropping in the new graphics engine, which was the result of months of work, there isn't too much more to look at with Lightspark 0.4.5. Obviously it doesn't yet support Adobe's brand new video acceleration method that's part of Adobe Flash 10.2, but that acceleration works damn well if you are using NVIDIA hardware to exploit VDPAU. With an Intel IGP, however, it will just heat your lap.
