Download f.lux 4.28 beta

A new beta release of f.lux has been released with version number 4.28. This program adjusts the color of the screen to the position of the sun. For example, the screen is brighter during the day and when the sun goes down the color becomes ‘warmer’. Not only is this calmer for the eyes, it could even help with sleeping problems. The program helps find your location on Earth so that it knows exactly when the sun sets. F.lux is available for Windows, Linux, macOS, iOS and Android, but the beta is currently only for Windows. Below is an overview of the major changes made in version 4, followed by the changelog of the last few versions.

what’s new:

• Analyzes your displays to show you how bright they are to your body: adjust your backlight and watch!
• Bedtime mode: warmer light before bed gets you ready for sleep, and works with all kinds of schedules
• Disable by app (so you don’t forget Photoshop)
• Backwards alarm clock: reminder not to stay up late
• Presets to help adjust your settings
• Color filters for eyestrain and other uses
• A wider range of color settings
• New hotkeys to adjust color (alt+shift+PgUp and alt+shift+PgDn)

Changes:

• Reduced impact on game frame rates
• Resolution independent interface, for high DPI displays
• DisplayLink monitors (connected by USB) work in a lot more cases now

Smart Lighting:

• Hue integration now supports more light types
• LAN API with support for telling other devices when f.lux changes

Changes in version 4.28

• Menus are juggled around to help simplify the UI (we are not done yet)
• Mouse cursor checkbox was broken, now fixed

Changes in version 4.26

• Software mouse cursor now switches on automatically when colors change, so you keep a hardware cursor during the day (you’ll have to turn it on again in Options)
• When you don’t enter your location, defaults are quite a bit better
• Fixes some cases for wake from sleep
• Some adjustments to vignette mode

Changes in version 4.25

• We noticed a lot of laptops are looking very “green-yellow” so we spent some time to figure out what was going on. We were able to pull some data out of the monitors that describe their colors better than Windows does, and so we’re trying to use that data to do more accurate colors now. In the Options menu, there is a checkbox called “Use Monitor Data for Calibration”. We’re turning this on for everyone in this build, so we’d like to know if you think it looks better, or worse!
• Second, we’ve improved “crushed shadows” by adjusting the response automatically when you dim your screen, so we think photos look a lot better in this new build
• There’s a new full-screen vignette mode we’re trying out, which manages to show about 60% less light, while still being readable (for some things).
• Enabling software mouse cursor doesn’t require a logout anymore
• Bugs fixed on wake from sleep. f.lux should always come back now.
• Notifiers should never steal keyboard focus, and hotkeys are usable in fullscreen apps/games, because we don’t pop notifiers that kick you back to the desktop
