The release of the Ubuntu 20.10 "Groovy Gorilla" distribution is available, which is classified as an interim release, updates for which are formed within 9 months (support will be provided until July 2021). Ready test images are created for Ubuntu, Ubuntu Server, Lubuntu, Kubuntu, Ubuntu Mate, Ubuntu Budgie, Ubuntu Studio, Xubuntu and UbuntuKylin (China edition).
Major changes:
- Updated app versions. The desktop has been updated to the GNOME 3.38 release and the Linux kernel to version 5.8. Updated versions of GCC 10, LLVM 11, OpenJDK 11, Rust 1.41, Python 3.8.6, Ruby 2.7.0, Perl 5.30, Go 1.13 and PHP 7.4.9. A new release of the LibreOffice 7.0 office suite has been proposed. Updated system components such as glibc 2.32, PulseAudio 13, BlueZ 5.55, NetworkManager 1.26.2, QEMU 5.0, Libvirt 6.6.
- Switched to using the default nftables packet filter.
- Official support for Raspberry Pi 4 and Raspberry Pi Compute Module 4 boards has been provided, for which a separate build with a specially optimized Ubuntu Desktop edition has been prepared.
- Added the ability to enable Active Directory authentication to the Ubiquity installer.
- The popcon (popularity-contest) package, which was used to transmit anonymized telemetry about downloading, installing, updating and removing packages, has been removed from the main composition.
- Access to the /usr/bin/dmesg utility is limited only to users belonging to the "adm" group. The reason cited is the presence in the dmesg output of information that can be used by attackers to simplify the creation of exploits for privilege escalation.
- Cloud Imaging Changes: Builds with dedicated cloud kernels and KVM to boot faster now boot without initramfs by default (regular kernels still use initramfs). To speed up the first load, we implemented the delivery of a pre-formed filling for snap, which allows you to get rid of the dynamic loading of the necessary components (seeding).
- Π Kubuntu KDE Plasma 5.19 desktop, KDE Applications 20.08.1, and Qt 5.14.2 library released. Updated Elisa 20.08.1, latte-dock 0.9.10, Krita 4.3.0 and Kdevelop 5.5.2.
- Π Ubuntu MATE as in the previous release, the MATE 1.24 desktop is shipped.
- Π Lubuntu proposed graphical environment LXQt 0.15.0.
- Ubuntu Budgie: Shuffler, an interface for quickly navigating open windows and grouping windows on a grid, has added a sticky neighbors feature and implemented command-line controls. Added support for finding GNOME settings in the menu and removed many distracting icons. Added Mojave theme with macOS-style icons and interface elements. Added a new applet with a full-screen interface for navigating through installed programs, which can be used as an alternative to the application menu. The Budgie desktop has been updated with a fresh code snippet from Git.
- Π Ubuntu Studio made the transition to using KDE Plasma as the default desktop (previously offered Xfce). It is noted that KDE Plasma has quality tools for graphic artists and photographers (Gwenview, Krita) and better support for Wacom tablets. We also switched to the new Calamares installer. Firewire support returned to Ubuntu Studio Controls (ALSA and FFADO based drivers available). Includes a new audio session manager forked from Non Session Manager and the mcpdisp utility. Updated Ardour 6.2, Blender 2.83.5, KDEnlive 20.08.1, Krita 4.3.0, GIMP 2.10.18, Scribus 1.5.5, Darktable 3.2.1, Inkscape 1.0.1, Carla 2.2, Studio Controls 2.0.8, OBS Studio 25.0.8, MyPaint 2.0.0. Removed Rawtherapee from base distribution in favor of Darktable. Jack Mixer returned to the main lineup.
- Π Xubuntu updated versions of Parole Media Player 1.0.5, Thunar File Manager 1.8.15, Xfce Desktop 4.14.2, Xfce Panel 4.14.4, Xfce Terminal 0.8.9.2, Xfce Window Manager 4.14.5, etc.
Changes in Ubuntu Server:
- Support for Active Directory has been improved in the adcli and realmd packages.
- The Samba 4.12 package is built with the GnuTLS library, resulting in a significant increase in encryption performance for SMB3.
- Dovecot IMAP server has been updated to release 2.3.11 with SSL/STARTTLS support for doveadm proxied connections and the ability to perform IMAP transactions in batch mode.
- The liburing library is included, allowing you to use the io_uring asynchronous I / O interface, which is ahead of libaio in performance (for example, liburing is supported in the samba-vfs-modules and qemu packages).
- A package with a system for collecting Telegraf metrics has been added, which can be used in conjunction with Grafana and Prometheus to build a monitoring infrastructure.
