Lunar

6.7.12

Improvements

• Improve Auto Blackout by ignoring displays with empty or incomplete `name
• Print CLI location and restart shell after installation

Fixes

• Fix Software Dimming not being applied instantly when using the lunar displays CLI

6.7.11

Fixes

• Fix Sync Mode not using nits on MacBook Air and iMac (Apple Silicon only)

6.7.10

Improvements

• Shave off another 250 milliseconds from the CLI startup time

Fixes

• Fix menu appearing on the main display instead of the one where the icon was clicked, on fullscreen apps
• Fix positioning of the new "Disable volume keys on display sleep" setting
• Fix resolution being changed erroneously

6.7.9

Improvements

• Disable volume keys handler on sleep and re-enable on wake to prevent CoreAudio from hanging and cause system lag
• Speed up CLI startup time

Fixes

• Fix a long-standing issue where LED Cinema and Thunderbolt displays would overflow the brightness value, causing the display to go dark at specific brightness levels (39 and 78)
• Fix Location Mode not being selectable when using manual coordinates

6.7.8

Fixes

• Move max DDC brightness back to 255 for Cinema and Thunderbolt displays
• Fix brightness being sent to the monitor continuously in Sensor Mode, even if the value hasn't changed
• Ensure the Sensor Mode Lux update interval is correctly used with wireless sensors

6.7.7

Fixes

• Fix nits OSD appearing erroneously when HDR state is being changed

6.7.6

Fixes

• Fix flickering in smooth transitions when holding the brightness keys
• Fix nits value not updating all the time

6.7.5

Features

• Smoother Sync Mode brightness adaptation

Fixes

• Fix printing SentryCrashExceptionApplication by mistake in the CLI output
• Fix nits OSD not appearing where it should after resolution change
• Ensure Full Range remains enabled even when the system reports an incomplete status

Improvements

• Add hidden setting syncModeBrightnessKeyPressedExpireSeconds

Showing OSD on target monitors in Sync Mode requires only taking into account the changes that happen within a waiting period after the brightness key press.

That period was previously 0.5 seconds, which was now increased to 1 second and made configurable via the syncModeBrightnessKeyPressedExpireSeconds hidden setting. Some systems take longer to propagate the brightness change events and this setting should help with that.

• Optimise code path leading from the Sync source brightness change to the Sync target brightness adaptation
• More intuitive nits range calculation in Sync Mode

6.7.4

Fixes

• Fix color adjustments not being applied anymore on some screens

  • when opening the lid of the MacBook while clamshell mode is disabled
• Stop brightness and lux CLI listeners when the socket closes

Features

Full Range XDR Brightness

This is a new approach for unlocking the 1600nits of brightness in Apple's XDR displays, developed in collaboration with Istvan from BetterDisplay.

It has the following key differences from the previous XDR Brightness method:

• It doesn't clip colors in HDR content - no more washed out colors
• The system adaptive brightness keeps working and uses the full range
• There's no lag when going from SDR to XDR brightness
• Can work in tandem with f.lux

Downsides:

• It only works on Apple XDR screens
• The screen will flash one or two times when toggling Full Range

The system will still adapt the maximum nits of brightness based on the ambient light, so you might get a max of 800 nits in a dark room and 1600 nits in sunlight.

Disabling the system adaptive brightness will turn off this behaviour.

Preset unlocking

The Change Screen Preset Shortcut now allows you to unlock various functions that are locked by macOS when using reference presets:

• Brightness Control
• Adaptive Brightness
• Night Shift
• True Tone

Improvements

• Allow overlay dimming to work on Airplay screens when the MacBook is in Blackout
• Automatically use the mirroring method for Blackout when the MacBook is connected to an wireless display

Fixes

• Disable Dark Mode after disabling Night Mode
• Ensure Night Mode does disable after unchecking it
• Fix app hanging when initializing Location Services in some cases
• Fix Dark Mode being disabled erroneously
• Make sure to re-enable keyboard backlight after disabling Blackout
• Fix CLI not working after a few standby cycles
• Fix rounded corners not being applied on app launch

6.5.0

Features

• Night Mode: minimize jarring flashes of white regions on dark backgrounds. This is a combination between:
  • lower whitepoint: lower the whitepoint of the screen to make white regions appear less bright
  • warm colors: filters blue light to further minimise eye strain on bright colors
  • enhanced contrast: keeps text readable even at such low brightness levels

The following video shows the difference between simply having Dark Mode on with a low brightness, and having Night Mode on top of that.

If you pay attention to the hand that is scrolling, you'll notice that the flashes of light from the white regions have less effect with Night Mode enabled. In the same way, your eyes will see less of a difference in perceived brightness between the dark background and the bright regions that may appear unexpectedly while scrolling on a web page.

The technique is quite similar to what f.lux does, but with the added benefit of enhancing contrast for readability.

Fixes

• Important fix on DDC commands causing a crash when the queue is full
• Allow http on non-local custom domains/IPs of light sensors
• Fix not keeping Disconnect API disabled with DisplayLink running
• Fix built-in screen having 100% brightness after waking up from sleep in some cases
• Make sure external sensor available state is kept up to date
  • Fixes a problem where both internal and external sensor data would be used at the same time

Improvements

• Limit Gamma whites and blacks sliders to avoid full black/white screens
• Allow disabling Sub-zero dimming by setting Min Brightness to 0
