Engst The f.lux team has released version 37.2 of [1]f.lux, the automatic screen color management utility to fix a battery drain issue and flashing when in 'movie mode' on some machines. The update also adds support for 'big latitudes' where the sun doesn't set or rise on some days, plus a Check for Updates button. For those using OS X 10.11 El Capitan who are experiencing colors left behind after the upgrade (when automatic brightness is enabled), the f.lux team has released version 37.3.
