GNOME 3.24 Released (softpedia.com)
prisoninmate quotes a report from Softpedia: GNOME 3.24 just finished its six-month development cycle, and it's now the most advanced stable version of the modern and popular desktop environment used by default in numerous GNU/Linux distributions. It was developed since October 2016 under the GNOME 3.23.x umbrella, during which it received numerous improvements. Prominent new features of the GNOME 3.24 desktop environment include a Night Light functionality that promises to automatically shift the colors of your display to the warmer end of the spectrum after sunset, and a brand-new GNOME Control Center with redesigned Users, Keyboard and Mouse, Online Accounts, Bluetooth, and Printer panels. As for the GNOME apps, we can mention that the Nautilus file manager now lets users browse files as root (system administrator), GNOME Photos imitates Darktable's exposure and blacks adjustment tool, GNOME Music comes with ownCloud integration and lets you edit tags, and GNOME Calendar finally brings the Week view. New apps like GNOME Recipes are also part of this release. The full release notes can be viewed here. Softpedia notes in conclusion: "As mentioned before, it will take at least a couple of weeks for the new GNOME 3.24 packages to land on the stable repositories of your favorite distro, which means that you'll most probably be able to upgrade from GNOME 3.22 when the first point release, GNOME 3.24.1, is out on April 12, 2017."
There is a perplexing amount of GNOME hate in the top comments. I'm a very happy user. I've been using Linux almost exclusively in all capacities since about 1999 and have sampled and/or used a lot of desktop environments. GNOME is the best, IMHO.

No, that is a serious thing. Colour temperature of the ambient light around you affects with your day-night cycle. We are made to respond to the sun's light which is colder in the morning (to wake you up) and warmer in the evening (which helps you sleep).
When the primary light source is your computer/device screen then that is what affects you the most.
This has been covered several times before here on Slashdot. Some that are easy to find.

However, I think that the change should not be abrupt but be gradual to better cohere with the sun's natural cycle. But I suspect that they chose to make it a special mode so as not to interfere with colour accuracy during work time.
Myself, I wish that I could also get LED bulbs that changed colour temperature gradually depending on the time of day, and that they wouldn't be expensive and hackable (Like Phillips ... ). I live in the North where some winter days are darker than summer nights, and thus artificial light is important all day.
