distribution release , which is categorized as a Long Term Support (LTS) release with updates for 5 years until April 2025. Installation and boot images are created for , , , , Ubuntu
Budgie, , и UbuntuKylin (China edition).
All :
- Desktop updated to release , which introduced a do not disturb mode to temporarily hide new notifications, added a separate application for managing GNOME Shell add-ons, modernized the design of the login and screen unlock interfaces, redesigned most system dialogs, introduced the ability to launch applications using a discrete GPU on systems with hybrid graphics, in overview mode, the ability to rename application directories has been implemented, the option to enable the parental control system has been added to the initial setup wizard, etc.
- The Yaru default theme has been redesigned, in addition to the previously available dark (dark headings, dark background and dark controls) and light (dark headings, light background and light controls) modes, a third completely light option will appear.

- Added support for 10-bit color depth.
- X11 now supports fractional scaling, which was previously only available when using Wayland. This feature allows you to choose the optimal size of elements on screens with a high pixel density (HiDPI), for example, you can increase the displayed interface elements not by 2 times, but by 1.5.
- Added a new splash screen to be shown on boot.
- The icon for quick navigation through the Amazon online store has been removed.
- Core Linux updated to release As in the fall release, the LZ4 algorithm is used to compress the kernel and the initial boot image (initramfs), which reduces boot time due to faster data decompression. Notable changes compared to kernel 4.15, used in Ubuntu 18.04 LTS mentions support for AMD Rome CPUs, Radeon RX Vega M and Navi GPUs, Qualcomm Snapdragon 845 SoCs, Intel Cannon Lake platforms, Raspberry Pi 2B, 3B, 3A+, 3B+, CM3, CM3+, and 4B boards, significant improvements in power management, improved USB 3.2 and Type-C support, a new mounting API, io_uring interface, pidfd, and AMD SEV (Secure Encrypted Virtualization) support in KVM.
- Updated system components and development tools: Glibc 2.31, BlueZ 5.53, OpenJDK 11, rustc 1.41, GCC 9.3, Python 3.8.2, ruby 2.7.0, Ruby on Rails 5.2.3, php 7.4, perl 5.30, go 1.13.
- Updated user and graphic applications:
Mesa 20.0, Qt 5.12.8, PulseAudio 14.0-pre, Firefox 75.0, Thunderbird 68.7.0, LibreOffice 6.4.2, GIMP 2.10.18, VLC 3.0.9. - Updated applications for servers and virtualization:
QEMU 4.2, libvirt 6.0, Bind 9.16, HAProxy 2.0, OpenSSH 8.2 (with support for FIDO/U2F two-factor authentication tokens and the ability to place settings in /etc/ssh/sshd_config.d/*.conf). Apache httpd has TLSv1.3 support enabled. - VPN support added WireGuard.
- The exact time synchronization daemon chrony has been updated to version 3.5 and is additionally isolated from the system through the connection of a system call filter.
- Development of the experimental feature of installation on a root partition with ZFS has continued. Implementation of ZFSonLinux updated before release with support for encryption, hot removal of devices, the "zpool trim" command, acceleration of the "scrub" and "resilver" commands. To manage ZFS, the zsys daemon is being developed, which allows you to run several parallel systems with ZFS on one computer, automates the creation of snapshots and manages the separation of system and data that changes during the user session. In different snapshots, you can contain different system states and switch between them. For example, in case of problems after installing updates, you can return to the old stable state by selecting the last snapshot. Snapshots can also be used to transparently automatically back up user data.
- Compared to the previous LTS release, Snap Store has replaced Ubuntu Software as the default interface for searching and installing regular and snap packages.
- Package building for the i386 architecture has been stopped. To continue running legacy programs that remain 32-bit only or require 32-bit libraries, build and ship 32-bit library packages.
- In system , used to store network interface settings, added support for configuring SR-IOV virtual network devices, GSM modems (via the NetworkManager backend), WiFi parameters (bssid/band/channel). It was also possible to set the ipv6-address-generation option for NetworkManager and emit-lldp for networkd.
- Python 3.8 has been added to the base distribution, and Python 2.7 packages have been moved to the universe repository and are not shipped by default. The remaining Python 2.7 packages in the distribution have been modified to use the /usr/bin/python2 interpreter. The /usr/bin/python file is no longer installed by default (creating /usr/bin/python bound to Python 3 requires the python-is-python3 package to be installed).
- By default, an ISO image is offered for all supported architectures. Ubuntu Server with the Subiquity installer, which performs installation in Live mode. Subiquity supports such operations as disk partitioning, language and keyboard layout selection, user creation, network connection configuration, RAID, LVM, VLAN, and network interface bonding. New features include automated installation using a JSON profile and the ability to install the bootloader on multiple disks at once (so that you can boot from any disk if the bootloader is damaged). Additionally, fixes have been made to simplify encryption, installation on multipath disks, and improve the reliability of using disks with other systems already installed.
- В KDE Plasma 5.18 desktop, KDE Applications 19.12.3 and Qt 5.12.5 framework are offered. The default music player is Elisa 19.12.3, which replaced Cantata. Updated latte-dock 0.9.10, KDEConnect 1.4.0, Krita 4.2.9, Kdevelop 5.5.0. Dropped support for KDE4 and Qt4 applications. KDE PIM has been removed from the base distribution, which should now be installed from the repository. An experimental session based on Wayland is proposed (after installing the plasma-workspace-wayland package, an optional item "Plasma (Wayland)" appears on the login screen).
- : MATE desktop updated to version . Added an interface for updating firmware using fwupd. Removed Compiz and Compton from distribution. Provided display of window thumbnails in the panel, the task switching interface (Alt-Tab) and the desktop switcher. A new applet for displaying notifications is proposed. Evolution is used as an email client instead of Thunderbird. When installing proprietary NVIDIA drivers, which can be selected in the installer, an applet is provided to switch between different GPUs on systems with hybrid graphics (NVIDIA Optimus).
- : Apps menu applet enabled by default and its own applet for managing network settings.
Added an interface for quickly switching desktop layouts (Budgie, Classic Ubuntu Budgie, Ubuntu Budgie, Cupertino, The One
and Redmond).
The core package includes the GNOME Firmware and GNOME Drawing applications.
Improved integration with GNOME 3.36. The Budgie desktop has been updated to version 10.5.1. Added anti-aliasing and font hinting settings. By default, the system tray applet is disabled (due to problems during operation). Applets are adapted for HiDPI screens. - : IN Ubuntu Studio Controls now separates settings for Jack Master, auxiliary devices, and PulseAudio layers. Updates include RaySession 0.8.3, Audacity 2.3.3, Hydrogen 1.0.0-beta2, and Carla 2.1-RC2.
Blender 2.82, KDEnlive 19.12.3, Krita 4.2.9, GIMP 2.10.18,
