What's new in this version:

What's new:
- Fix for a battery drain issue on some machines
- Fix for flashing with "movie mode" on some machines
- Updated Sparkle (automatic updater)
- Now 10.7 minimum (and 64-bit only) due to the Sparkle update
- Support for "big" latitudes where the sun doesn't set or rise some days

What's not fixed on all machines (outside our control):
- White spots on video
- Issues with "automatic brightness" (e.g., darkroom appears not to work on some models with it on, still), but this is getting better with dot-revs.
- Finally, if you are still having trouble with "automatic brightness", we added a pref for testing a fix we made earlier, which is now off. To use, type this to the Terminal: "defaults write org.herf.Flux ambientfix 1", and restart f.lux.
