The Debian Project has announced the release of Debian 13.3, the third point update to its stable Trixie operating system series. This update, arriving nearly two months after version 13.2, includes 108 bug fixes and 37 security updates to enhance stability and security. It provides refreshed installation media for new users while existing installations can be updated via standard package tools.
The Debian Project made Debian 13.3 available on January 10, 2026, as an update to the Debian 13 “Trixie” GNU/Linux distribution. This point release consolidates fixes for security vulnerabilities and functional issues across various packages, ensuring a more stable experience for users. Although most updates were already accessible through security repositories, Debian 13.3 bundles them into the installation media, making it ideal for fresh setups on new hardware without the need for extensive post-install downloads.
Key enhancements include stable upstream releases for packages such as Ansible, Apache2, Flatpak, Go components, PostgreSQL 17, QEMU, and the Linux kernel. Security fixes address critical issues like integer overflows, parsing errors, heap overflows, memory corruption, denial-of-service vulnerabilities, and bounds-check failures. Core libraries including glibc and glib2.0 have received important patches, while desktop components—such as GNOME Shell and applications like Thunderbird, Chromium, and VLC—along with multimedia libraries, benefit from vulnerability mitigations. Additionally, updated Intel microcode and installer adjustments, including an increased kernel ABI, are incorporated.
Installation images support multiple architectures: amd64, arm64, armhf, ppc64el, riscv64, and s390x. Live images, available only for amd64, come preinstalled with desktop environments like KDE Plasma 6.3.6, GNOME 48, Xfce 4.20, Cinnamon 6.4.10, LXQt 2.1, MATE 1.26.1, LXDE 0.11.1, and the IceWM window manager on the Junior edition. For existing Trixie users, updates are straightforward using the command sudo apt update && sudo apt full-upgrade in a terminal.
In parallel, the project released Debian 12.13 for the older Bookworm series, featuring 96 bug fixes and 85 security updates. No new features are added in these releases; the focus remains on reliability and protection against known threats. Users can verify their Debian version by running cat /etc/debian_version.
