Debian 12 Bookworm: Best New Features
We give you a summary of the new features and enhancements of the Debian 12 Bookworm (upcoming) release.
Debian 12 has been under development for a few months and slowly moving towards a final release. As of publishing this, it is currently under the hard freeze. That means no major package changes or enhancements are expected.
This release comes with several new features and improvements, making it an exciting release for Debian enthusiasts. In this article, we will discuss the best new features of Debian 12 Bookworm and how they can benefit users.
Let’s take a look.
Debian 12 Bookworm: New Features
Linux Kernel
This release features Linux mainline Kernel 6.1, released in December 2022. Timeline-wise, Debian 12 is only one Kernel release behind as of now. Hence, you get the latest and greatest hardware support with stable Kernel 6.1.
Highlights features of this Kernel include initial Rust framework support, updates to Intel and AMD’s upcoming CPU/GPU line-ups, performance improvements of btrfs and other file systems and more.
We already have a dedicated article about Kernel 6.1 features if you want to learn more.
Non-free packages in the installer
A critical change related to the Debian ISO files arrives in Debian 12. Since the beginning, Debian has provided different ISO files for “Free” and “non-free” packages. The proprietary “non-Free” packages are part of separate ISO files. Hence, if you need driver support for your special hardware, then you can download separate ISO files for your laptop/desktop/servers.
However, this experience makes it a little confusing for the end user to pick the correct Debian ISO. The Debian team launched a community voting last year to pick the best option to handle “non-free” packages.
As per the results, the primary ISO files now contain both free and “non-free” ISO files.
So, what changed?
When you try to download official Debian ISO files, you only need to choose one ISO file (DVD size) containing everything. Furthermore, the small net-installation ISO is also present, including “non-free” firmware.
You can look at this guide regarding Debian ISO.
Pipewire by default for GNOME
If you use GNOME desktop in Debian Linux, then a piece of good news for you.
Debian 12 with GNOME desktop making Pipewire and Wireplumber manager by default sound server, replacing Pulseaudio. The modern Pipewire is already introduced in Ubuntu, Fedora, Pop!_OS and other leading distros.
A new version of Apt (2.6) package manager
Debian 12 is introducing the latest version of apt package manager version 2.6. Apt 2.6 version specifically handles the non-free ISO image support introduced in this release. The changes include the non-free firmware will be enabled by default, and apt will show updates to the non-free packages.
Desktop environments
All the major desktop environments are now up to date in Debian 12, except GNOME. Because GNOME 44 was released just a few days back, it won’t make it to Bookworm due to schedule conflicts. Debian 12 is already on hard freeze.
Hence, in Debian 12, you get the GNOME 43version which is not that far behind compared to the latest release. Furthermore, if you are shifting from Debian 11, then it will be a huge GNOME upgrade.
Fortunately, KDE Plasma 5.27 is now available in this release. KDE Plasma is the final Plasma 5 version and is likely to become LTS until Plasma 6 is ready. Hence, it was a significant upgrade. The KDE Plasma maintainers managed to pull this off.
In addition, Xfce 4.18 in Debian 12 is bringing an improved desktop experience with stunning Thunar features. Also, LXQt 1.2, MATE 1.26 and LXDE 11 are the latest versions featured in Debian 12.
Here’s a summary:
- GNOME 43
- KDE Plasma 5.27
- LXDE 11
- LXQt 1.2
- MATE 1.26
- Xfce 4.18

Default theme and wallpapers
In every release, Debian introduces some stunning artwork from the community. Debian 12 default artwork themed as “Emerald”.
“Elegantly polished and chiseled, or in their raw and natural state, gemstones can have an infinite number of shapes.”
With the Emerald theme, the creator wanted to combine light and minerals in a clean, almost ethereal design.
The default theme and banners are visible across the installer, animated Plymouth, wallpaper and all the places.
Here are some of the images picked up from the official gallery.
