After 25 months of development the Debian project is proud to present its new stable version 10 (code name „buster”), which will be supported for the next 5 years thanks to the combined work of the Debian Security team and of the Debian Long Term Support team.

Debian 10 „buster” ships with several desktop applications and environments. Amongst others it now includes the desktop environments: Cinnamon 3.8, GNOME 3.30, KDE Plasma 5.14, LXDE 0.99.2, LXQt 0.14, MATE 1.20, Xfce 4.12 .

In this release, GNOME defaults to using the Wayland display server instead of Xorg. Wayland has a simpler and more modern design, which has advantages for security. However, the Xorg display server is still installed by default and the default display manager allows users to choose Xorg as the display server for their next session.

For those in security-sensitive environments AppArmor, a mandatory access control framework for restricting programs’ capabilities, is installed and enabled by default. Furthermore, all methods provided by APT (except cdrom, gpgv, and rsh) can optionally make use of „seccomp-BPF” sandboxing. The https method for APT is included in the apt package and does not need to be installed separately.

Network filtering is based on the nftables framework by default in Debian 10 „buster”. Starting with iptables v1.8.2 the binary package includes iptables-nft and iptables-legacy, two variants of the iptables command line interface. The nftables-based variant uses the nf_tables Linux kernel subsystem. The „alternatives” system can be used to choose between the variants.

The UEFI („Unified Extensible Firmware Interface”) support first introduced in Debian 7 (code name „wheezy”) continues to be greatly improved in Debian 10 „buster”. Secure Boot support is included in this release for amd64, i386 and arm64 architectures and should work out of the box on most Secure Boot-enabled machines. This means users should no longer need to disable Secure Boot support in the firmware configuration.

The cups and cups-filters packages are installed by default in Debian 10 „buster”, giving users everything that is needed to take advantage of driverless printing. Network print queues and IPP printers will be automatically set up and managed by cups-browsed and the use of non-free vendor printing drivers and plugins can be dispensed with.

With a 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 „buster” fulfills the high expectations that users have of a stable Debian release.

A total of ten architectures are supported: 64-bit PC / Intel EM64T / x86-64 (amd64), 32-bit PC / Intel IA-32 (i386), 64-bit little-endian Motorola/IBM PowerPC (ppc64el), 64-bit IBM S/390 (s390x), for ARM, armel and armhf for older and more recent 32-bit hardware, plus arm64 for the 64-bit „AArch64” architecture, and for MIPS, mips (big-endian) and mipsel (little-endian) architectures for 32-bit hardware and mips64el architecture for 64-bit little-endian hardware.

If you simply want to try Debian 10 „buster” without installing it, you can use one of the available live images which load and run the complete operating system in a read-only state via your computer’s memory.

These live images are provided for the amd64 and i386 architectures and are available for DVDs, USB sticks, and netboot setups. The user can choose among different desktop environments to try: Cinnamon, GNOME, KDE Plasma, LXDE, MATE, Xfce and, new in buster, LXQt. Debian Live Buster re-introduces the standard live image, so it is also possible to try a base Debian system without any graphical user interface.
