RC3 has been published – complete with automatic HSV color conversion. You can get the new code from here:

RC3 fixes a bug that came up if the Clock and Data pins were on the same port. There are also simple new example programs, and a super-handy new “RGBCalibrate” sketch which is designed to help you quickly and easily figure out the ‘order’ of the R, G, and B LEDS on any given strip.
As advertised, RC3 also includes automatic HSV to RGB color conversion, so you can now work with HSV colors much more easily. The simplest example of this is also the most compelling; you can assign an HSV color directly to an RGB color, and the conversion is fast and automatic:
// Set pixel to hue=160, full saturation & brightness
leds[i] = CHSV( 160, 255, 255);
There’s new documentation up on the wiki, now, too, covering the basics of HSV color, automatic color conversion, etc.

You may want to start from the top of that page, or skip down to the section called “Setting HSV Colors”.
Enjoy the new code. Please let us know if it’s working for you, or if it isn’t. We feel like we’re getting pretty close to “full release” now, but we want to make sure we address quickly any problems that come up.
