After several years of development, the well-known f.lux program has finally been
updated to version 3.9 (without beta). It implemented a large number of new features, some of which were not enough before.

Recall that f.lux is a program that changes the color profile of a monitor, depending on the time of day. At night, warm color tones are set up, which correspond to artificial lighting in the apartment, cold ones during the day, corresponding to daylight. Thus, the eyes are much less tired, because the glow of the monitor becomes more natural and corresponds to the environment.
Most importantly, in the new version, the restriction on the minimum color temperature of 3400 ° K has been removed. Now the temperature can be reduced to 2700 ° K or even less, if you so wish.
