Debian Linux is used by millions of users across desktops, servers, and it is the foundation of all the popular descendant operating systems such as Ubuntu and its derivatives. This Universal Linux Operating system Debian 11 Bullseye is the next stable version following the current stable Debian 10 Buster, which is currently going through the bug fix iterations.

In every Debian iterations, which typically spans around multiple years, we see thousands of packages are upgraded, included, and of course, removed. Following the hard freeze of Debian 11, we have now a fair idea about what are the new features and upgrades and what are the packages we say goodbye to in this release.

Before we summarize, if you are planning to install Debian 11 (sid), you can get the test copy right now and install it. I have included the download link at the end of this page.

  • 32-bit PC (i386) and 64-bit PC (amd64)

Debian Bullseye includes the current LTS kernel – Linux Kernel 5.10 which brings a fairly new set of hardware support, bug fixes, and performance improvements. Considering the Debian lifecycle, this is the ideal Kernel version you get with this release.
