Version 11.2 Release Date: December 18, 2021 (Release Notes)
After 2 years, 1 month, and 9 days of development, the Debian project is proud to present its new stable version 11 (code name bullseye), which will be supported for the next 5 years thanks to the combined work of the Debian Security team and the Debian Long Term Support team.
Debian 11 (bullseye) ships with several desktop applications and environments. Amongst others it now includes the desktop environments:
This release contains over 11,294 new packages for a total count of 59,551 packages, along with a significant reduction of over 9,519 packages which were marked as
obsolete and removed. 42,821 packages were updated and 5,434 packages remained unchanged.
bullseye becomes our first release to provide a Linux kernel with support for the exFAT filesystem and defaults to using it for mount exFAT filesystems. Consequently it is no longer required to use the filesystem-in-userspace implementation provided via the exfat-fuse package. Tools for creating and checking an exFAT filesystem are provided in the exfatprogs package.
Most modern printers are able to use driverless printing and scanning without the need for vendor specific (often non-free) drivers.
bullseye brings forward a new package, ipp-usb, which uses the vendor neutral IPP-over-USB protocol supported by many modern printers. This allows a USB device to be treated as a network device. The official SANE driverless backend is provided by sane-escl in libsane1, which uses the eSCL protocol.
bullseye activates its persistent journal functionality, by default, with an implicit fallback to volatile storage. This allows users that are not relying on special features to uninstall traditional logging daemons and switch over to using only the systemd journal.
The Debian Med team has been taking part in the fight against COVID-19 by packaging software for researching the virus on the sequence level and for fighting the pandemic with the tools used in epidemiology; this work will continue with focus on machine learning tools for both fields. The team's work with Quality Assurance and Continuous integration is critical to the consistent reproducible results required in the sciences. Debian Med Blend has a range of performance critical applications which now benefit from SIMD Everywhere. To install packages maintained by the Debian Med team, install the metapackages named med-*, which are at version 3.6.x.
Chinese, Japanese, Korean, and many other languages now have a new Fcitx 5 input method, which is the successor of the popular Fcitx4 in
buster; this new version has much better Wayland (default display manager) addon support.
bullseye includes numerous updated software packages (over 72% of all packages in the previous release), such as:
With this broad selection of packages and its traditional wide architecture support, Debian once again stays true to its goal of being
The Universal Operating System. It is suitable for many different use cases: from desktop systems to netbooks; from development servers to cluster systems; and for database, web, and storage servers. At the same time, additional quality assurance efforts like automatic installation and upgrade tests for all packages in Debian's archive ensure that
bullseye fulfills the high expectations that users have of a stable Debian release.
The Debian Project is an association of individuals who have made common cause to create a free operating system. This operating system that we have created is called Debian.
An operating system is the set of basic programs and utilities that make your computer run. At the core of an operating system is the kernel. The kernel is the most fundamental program on the computer and does all the basic housekeeping and lets you start other programs.
Debian systems currently use the Linux kernel or the FreeBSD kernel. Linux is a piece of software started by Linus Torvalds and supported by thousands of programmers worldwide. FreeBSD is an operating system including a kernel and other software.
A large part of the basic tools that fill out the operating system come from the GNU project; hence the names: GNU/Linux, GNU/kFreeBSD, and GNU/Hurd. These tools are also free.
Of course, the thing that people want is application software: programs to help them get what they want to do done, from editing documents to running a business to playing games to writing more software. Debian comes with over 43000 packages (precompiled software that is bundled up in a nice format for easy installation on your machine), a package manager (APT), and other utilities that make it possible to manage thousands of packages on thousands of computers as easily as installing a single application. All of it free.
It's a bit like a tower. At the base is the kernel. On top of that are all the basic tools. Next is all the software that you run on the computer. At the top of the tower is Debian — carefully organizing and fitting everything so it all works together.
Debian will run on almost all personal computers, including most older models. Each new release of Debian generally supports a larger number of computer architectures.
There are a few companies that make support difficult by not releasing specifications for their hardware. This means you might not be able to use their hardware with GNU/Linux. Some companies provide non-free drivers, but that is a problem because the company could later go out of business or stop support for the hardware you have. We recommend that you only purchase hardware from manufacturers that provide free drivers for their products.
Don't take our word for it - try Debian yourself. Since hard disk space has become less expensive, you can probably spare about 2GB. If you don't want or need a graphical desktop, 600MB are sufficient. Debian can be easily installed on this extra space and can coexist with your existing OS. If you eventually need more space, you can simply delete one of your OSes (and after you see the power of a Debian system, we are confident you won't delete Debian).see the power of a Debian system, we are confident you won't delete Debian).
