Official Raspberry Pi OS Is Now Based on Debian GNU/Linux 11 “Bullseye”

The latest Raspberry Pi OS release, dated October 30th, 2021, is the first to switch bases from the old-stable Debian GNU/Linux 10 “Buster” to the Debian GNU/Linux 11 “Bullseye” operating system series, and it uses the Linux 5.10.63 LTS kernel by default.

But the Debian Bullseye rebase is just the cherry on top, as the newest Raspberry Pi OS release features all of its desktop components and applications build against the GTK+ 3 open-source application framework for the in-house built PIXEL desktop environment based on LXDE.
