- This tries even more to fix the "white cursor" bug in 10.15.1, but we are not sure yet if we've got it.

New in F.lux 36 Beta (Aug 20, 2015)
- Dim on disable It’s always been painful to disable f.lux for a color check or late-night design work, so we’ve provided a new option that dims your screen (a lot) when you disable. Check out the “Options” menu for this feature.
- Backwards alarm clock For years we’ve wanted an alarm clock that answers the question, “How much sleep will I get if I go to bed now?” So we made a little version of it for f.lux.
- Better transitions If you woke up your laptop late in the day, f.lux used to do a very slow transition (as if you were “used to” the orange color). Now it transitions quickly to daylight instead. Also, we’ve tuned up behavior at night and in the morning for “bedtime” mode: the night-time and early morning transitions are longer now.
- Expanded daytime settings For users who prefer very warm settings during the day, we’ve made an option that lets the sliders go all the way to 1900K, all the time. We prefer accurate color during the day, but quite a few people have asked for extra control like this. You can find this feature in the Options menu.
- Less CPU We made improvements to the profile writer for dual-GPU macs. So this new version should have less impact on those systems especially.
- Fixes for El Capitan f.lux is unfortunately incompatible with Apple’s “Ambient light compensation” feature, so we’ve turned it off while f.lux is running.
- Melanopic lux analysis A new screen analyzer in the About box.
New in F.lux 34.0 (Oct 27, 2014)
- A "Dark Mode"-compatible icon
- f.lux can switch automatically to OS X "dark mode" at sunset
- Ability to adjust system color profile for dual-GPU Macbook Pros: keeps screen from flashing when changing apps
- More accurate sunset and sunrise times
- Improvements to Darkroom animations and text quality
- Improved timing accuracy when your machine sleeps
- Fixed bugs with sleeping late on weekends
- NOTE: Please don't upgrade if you are running Leopard (10.5) or earlier.
New in F.lux 30.1 (Apr 9, 2014)
- daytime slider goes down to 2700K now, instead of 3400K before
New in F.lux 30.0 Beta (Mar 14, 2014)
- New warmer bedtime setting, with a custom schedule based on when you wake up
- Visualization of your day
- New effects and adjustments: movie mode, disable by app, and disable until sunrise.
- Notifiers go away after 30 seconds, rounding fixes, UI fixes.
New in F.lux 28.0 Beta (Mar 8, 2014)
- Improvements, Movies and Darkroom:
- There’s a Movie Mode to watch movies while preserving shadow detail, skintones, and sky colors. It lasts 2½ hours, longer than most feature films.
- There’s a way to disable f.lux until sunrise.
- There’s even a super-red mode we call Darkroom.
- Reworked all animations to make them smoother and cause less impact on your Mac.
- f.lux now works with your actual schedule:
- f.lux adjusts to your actual day, not just sunrise and sunset.
- It looks nice, showing you a visualization of your day.
- There are tons of new effects and adjustments.
- Your schedule:
- The new version of f.lux makes a schedule just for you, so you can use a screen that knows when you sleep, as well as when the sun’s up. We found a way to combine your day with sunrise and sunset.
- With the new f.lux, your screen warms up to make things look better at sunset. But then later, around the time you would start feeling sleepy, we do a little more, helping you get to bed on time. We've even tried to time this second phase with your body's natural release of melatonin. You may find you want a more moderate effect at sunset now, because the bedtime setting can be more intense.
New in F.lux 23.0 (Sep 30, 2013)
