f.lux 4.108:

  • Improves support for DisplayLink (docking stations and USB-connected displays) and older GPUs.
  • Fixes some crashes.

f.lux 4.103:

  • We are seeing a memory leak from a bug in the latest version of Windows 10 (18362), so for now, we’ve made f.lux restart (quietly) when RAM usage gets too high. Hopefully this will be fixed soon.
  • The “surface keys” menu item is visible again in options.

f.lux 4.84:

  • This new version of f.lux has a grayscale mode and new key to turn it on: Windows + End.
  • You may already know about Tristan Harris and the Center for Humane Technology. They’ve explained how apps mess with our attention, so even the colors used on our screens are chosen to distract you. At first, we didn’t think this problem would be as bad on the desktop as it is on your phone.
  • The big surprise is how distracting the icons on the top and bottom of your screen are. These icon colors are the kind of thing you see in candy stores and on fire alarms, but we have to ignore them just to get work done. Without those colors, your computer looks more like a magazine that can help you focus on reading or thinking—it feels different, like a sheet of paper.
  • Also, turning your devices to grayscale does not remove blue light, so f.lux will continue to do what it does.
  • In this version, there’s also dusk-to-dawn support for people with Hue lights, so you can put Hue lights outside and use f.lux to turn them off during the day.
  • There are some bugfixes too.

f.lux 4.78:

  • Fixed bugs that caused sliders to draw wrong at 125% and 200%.
  • Slightly slower dimming with Alt-PgDn.
  • Windows 10 fixes.
  • Installer fixes.

f.lux 4.76:

  • More flashing fixes.
  • Disabled function-key hotkeys (you can turn them on again by hand).
  • Fixes a problem with the recent Windows 10 April update that resets f.lux’s color settings when devices are added to the system (including headphones and mice).
  • Fixes some crash bugs.
  • Adjust warmth of Hue lights (relative to screen).
  • Early support for LIFX via LAN API.
  • Early support for YeeLight (Xiaomi Mi) via LAN API.
  • Options menu reorganized (so there can be more).
  • Checkbox to allow a laptop to sleep even when lighting controller is on.
  • Some installer and crash fixes.

  • Fixed Bugs.
