In October, we celebrated the release of Raspberry Pi OS Bookworm.
Raspberry Pi OS Bookworm is extremely ambitious.
It makesseveral changesto Pi OS' underlying architecture and replaces the old X11 display system with Wayland.

In effect, the operating system is far less cumbersome, far more attractive, and potentially more secure.
But an OS revision of this scale can be buggy.
Major Pi OS versions usually get their first “bug-fix release” after just one or two weeks.
This time, it tooktwo monthsto patch the OS.
The default Raspberry Pi OS theme, called PiXflat, was introduced in 2019.
As explained by Simon Long, the PiXflat theme is basically a long CSS file.
Unfortunately for Simon Long, the color values in PiXflat were hard coded.
Every update to the light theme would need to be manually applied to the dark theme.
So, all of PiXflat’s color values were replaced by variables.
Creating a variation on the PiXflat theme is now a simple task.
A small window will appear onscreen.
Navigate to the “System” tab, and grab the dark theme.
