New in f.lux 4.112 Beta (Nov 20, 2019)
- We added “Solar time” to the preferences, because we’re think it’s important. It’s not done because it’s going to have a more prominent role in the future, but for now, it’s here just to spark some discussion.
- If your solar time is after the current clock time, it’s likely that you live in a place that’s easy for night owls to be (because they can wake up late). And if you’re in a place where the solar time is much earlier than what your clock says, it’s easier for early birds, because they can go to bed early.
- Most of us wake up with our clocks (about 80% of people wake with an alarm clock), but our bodies tend to synchronize to the light we see. So when these two signals get far out of alignment, we sleep worse and have more health problems.

New in f.lux 4.84 (Nov 7, 2018)
- 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.

- Some adjustments to vignette mode
New in f.lux 4.25 Beta (May 8, 2017)
- This version tries to improve color calibration and fixes some bugs. What’s new:
- 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
New in f.lux 4.21 Beta (May 8, 2017)
- In this version, we’re showing everyone a little bit of the way we think about f.lux, giving you some measurements that we think are important. So far, we’ve not really brought “you” and your circadian timing into the f.lux interface.
- How light affects you:
- In this new build, we’ve exposed one of our models of how the light from screens affects your body (based on your screens’ sizes, and using our 5,000-person survey to approximate your viewing distance).
- As you adjust settings in f.lux now (or even as you change your laptop’s backlight, which is important), you’ll see one of five common-sense scores for how much light you’re seeing.
- As well, you’ll see a percentage, which we call “% daylight”. It’s a score for how much circadian effect the light you’re seeing might have, compared to broad daylight.
- But it’s also important to say, everyone’s a little bit different, so this is just a guideline. You might be more sensitive (especially if you’re under 20) or less sensitive (if you’re over 50, or if you spend a lot of time outdoors).
- Is light making you earlier or later? It’s about time too:
- Light you see in the morning makes your internal clock “advance” or set itself earlier, and light you see at night makes your clock “delay”. When these adjustments cancel out, your clock stays in about the same place. When you see too much light at night, your clock delays and you want to stay up later.
- This new f.lux version indicates the times of day that light is likely to make you later or earlier, so if you open the Preferences screen at night you will see “Light is making you later” and correspondingly “Light is making you earlier” in the morning.
- Other changes and fixes in this update:
- Notifications are redesigned, when you use the hotkeys (alt-pgup, alt-end, etc)
- Some extra support for wide color ranges on Windows 7
- Gaming mode (safe mode) is removed, because we’ve incorporated everything it does, finally. Use “very fast” transitions if you notice problems
- We now ask for the “earliest” time you wake up, to clarify what you should do when you have a variable schedule
New in f.lux 4.20 Beta (May 8, 2017)
- Optimized background performance more (should improve framerate drops), fixed some bugs
- Added ability to toggle software cursor in the Options (prevent white cursors!) - requires a reboot or logout
New in f.lux 4.19 Beta (May 8, 2017)
- Default to “slow transition” on purpose! We thought we had done that already, but people who had the old version were getting a fast transition.

New in f.lux 4.18 Beta (Apr 5, 2017)
