Focal Fossa 20.04
Ubuntu 20.04 LTS, codenamed Focal Fossa, is a long-term support release and was released on 23 April 2020.[337] Ubuntu 20.04.1 LTS was released on 6 August 2020.[338]
As an LTS release, it will provide maintenance updates for 5 years, until April 2025. This release is based on the long-term supported Linux kernel 5.4 which adds support for new hardware, including Intel Comet Lake CPUs and initial Tiger Lake platforms, Qualcomm’s Snapdragon 835 and 855 SoCs as well as AMD Navi 12 and 14 GPUs.[339] It also enables support for the exFAT filesystem and the open-source WireGuard VPN, as well as integration with Livepatch which allows for reboot-free kernel updates. A new Linux Security Module named Lockdown, disabled by default, was introduced in this kernel release and aims to prevent high-privileged root accounts from interacting with the underlying kernel by restricting certain kernel functionality, disallowing execution of arbitrary code and enforcing kernel module signatures among others.[340][341]
An updated toolchain offers glibc 2.31, OpenJDK 11, Python 3.8.2, php 7.4, perl 5.30 and Go 1.13. Python 2 is no longer used and has been moved to the universe repository. This release uses GNOME 3.36 which brings improvements to the user interface including a revamped login screen and refreshed Yaru theme. Improvements have also been made to the system menu and the installation screen, which now shows a graphical drive checking routine.[342] Moreover, the OEM logo is now displayed during boot. The Ubuntu Software Center will now install packages from the Snap Store, while it also adds an option for selecting the desired release channel to install from. This release also ended all support for the 32-bit architecture.[343][344]
