New Concept build for the Xperia X brings Night Light, January security update

Sony's Concept for Android program is still going strong on the Xperia X. Those who are running the stock-ish experience can look forward to a new update today, that is currently rolling out for everyone who chose the Experimental track when switching to the Concept builds.
The new update comes less than a month after the last one, which brought Android 7.1.1 Nougat with it. Today's release isn't as important, but it does nevertheless contain Google's January security patches.
Additionally, you'll get an updated Home launcher and Xperia Transfer Mobile app. But perhaps the most important new feature is Night Light, which will filter blue light from the screen when activated through Settings. This is becoming a pretty standard feature on smartphones these days, as blue light at night is said to mess with your sleep cycle. Hence, using the Night Light at night should make you fall asleep easier.
You can program the feature to turn itself on automatically from sunset to sunrise, or do it manually if you want to. After applying the new update you'll be running build N4F26I9, as seen in the screenshots above. This is still based on Android 7.1.1, of course.
