Debian 11 Based Raspberry Pi OS 2021-10-30 Update Available to Download, Raspberry Pi OS is a Debian-based distribution custom-built for Raspberry Pi computers. The development team have published a new version of Raspberry Pi OS which carries the code name “Bullseye”.
The new version is based on Debian 11 and upgrades a number of desktop components. “All of the desktop components and applications are now using version 3 of the GTK+ user interface toolkit. GTK+ is a layer of software that applications can use to draw standard user interface components (known as ‘widgets’) such as buttons, menus and the like, so that all applications have a consistent look and feel. Up until now, most of the desktop has used version 2 of the GTK+ toolkit, but increasing numbers of Debian applications are using GTK+3, so to try and keep things consistent, we’ve upgraded all our software and the desktop itself to the newer version. GTK+3 has been around for several years now, and people have occasionally asked why we didn’t move to it before now. The simple answer is that many things are much easier to do with GTK+2 than with GTK+3, particularly when it comes to customising the appearance of widgets – GTK+3 has removed several useful features which we relied upon. It has ended up being necessary to find work-arounds to a lot of these – hopefully no one will notice them and everything will still work as before!” Additional details can be found in the project’s.
