Il desktop manager utilizzato è Unity, sviluppato dalla stessa Canonical, ma sono disponibili anche gli altri desktop manager (Gnome, KDE, XFCE…)

Versione 21.10

Questa versione contiene (in Inglese):

Linux kernel

Linux 5.13 440 introduces support for new hardware and some less new:

• Future Intel and AMD chips, such as Intel Alderlake S or AMD Adebaran.
• Microsoft Surface Laptops and tablets 312.
• Rudimentary Apple M1 support.
• See also Linux 5.12 changes 398 for new features since 21.04.

As well as the usual plethora of bug fixes across the map.

Toolchain Upgrades

GCC was updated to the 11.2.0 release, binutils to 2.37, and glibc to 2.34. LLVM now defaults to version 13. golang defaults to version 1.17.x. rustc defaults to version 1.51.

OpenJDK 18 is now available (but not used for package builds).

Security Improvements

nftables is now the default backend for the firewall.

Base System

• systemd is being switched to the “unified” cgroup hierarchy (cgroup v2) by default. If for some reason you need to keep the legacy cgroup v1 hierarchy, you can select it via a kernel parameter at boot time: systemd.unified_cgroup_hierarchy=0 (bug 1850667 28)

Ubuntu Desktop

• Wayland sessions are now available while using the Nvidia proprietary driver.
• PulseAudio 15 330 introduces support for Bluetooth LDAC and AptX codecs, as well as HFP Bluetooth profiles providing better audio quality.
  • The recovery key feature at installation time has been improved. The recovery key is now optional, stronger and editable.

GNOME

Ubuntu 21.10 includes GNOME version 40 807, including a new and improved Activities Overview design. Workspaces are now arranged horizontally, and the overview and app grid are accessed vertically. Each direction has accompanying keyboard shortcuts, touchpad gestures and mouse actions.

Updated Applications

• Firefox version 93 is now seeded as a snap by default 227, instead of a deb package. The snap is jointly maintained by Mozilla (its publisher) and Canonical. The deb package remains available in the archive and will continue receiving updates for the lifetime of Ubuntu 21.10.
• LibreOffice version 7.2.1
• Thunderbird version 91.1.2

Updated Subsystems

• PulseAudio version 15.0 330
• BlueZ version 5.60 102
