Ubuntu 21.10 "Impish Indri" - Top New Features
Ubuntu is a popular choice for both experienced and new Linux users. Here are the top new features of Ubuntu 21.10 "Impish Indri";
- The new 21.10 release uses a new interface called Gnome 40 that starts with the Activities view instead of an empty desktop. This is the first Ubuntu release to ship with a complete GNOME 40 desktop, as the Ubuntu 21.04 release only offered GNOME 40 apps on top of the GNOME 3.38 desktop environment.
- Ubuntu 21.10 sticks to the same look and feel that was used since 2004 with the Ubuntu 11.04 “Natty Narwhal” release, namely with the Ubuntu Dock on the left side of the screen and the menubar at the top of the screen.
- Talking about look and feel, Ubuntu 21.10 features an improved Yaru theme to accommodate the GNOME 40 desktop environment and removes the mixed Light and Dark theme from the Appearance panel in System Settings, which was used in previous releases.
- The Favorites bar is now at the bottom of the screen and is similar to macOS. In addition, rounded corners attract attention in windows, Gnome applications, and many areas.
- On the other hand, security has been increased for both amd64 and arm64 architectures, and performance is minimally affected. Also supported is Kernel Electric Fence, a runtime memory fault detector.
- Another major change in Ubuntu 21.10 is the Firefox web browser as a Snap package by default. The main advantage of Firefox Snap is that Ubuntu users will get new versions the same moment they’re released upstream, but it also improves the security of the web browser since it's a sandboxed app.
There are also some innovations targeting developers. Full compatibility is provided for Windows Subsystem for Linux. PHP received an update to version 8, while the GNU Compiler Collection was upgraded to version 11 for C and C++, among other languages.
For Raspberry Pi users, Ubuntu 21.10 brings support for Sense HAT (can be installed using sudo apt install sense-hat) and Sense HAT desktop emulator (can be installed using sudo apt install sense-emu-tools). Moreover, this release removes support for Raspberry Pi CM3 due to a lack of storage capacity.
Impish Indri is not the Long Term Support version of the operating system but debuted as the last intermediate version before the next LTS to be held in April 2022. An ISO of Ubuntu 21.10 is available on Docker Hub and Amazon ECR Public Registry. You can also download it from Ubuntu.com or update your existing installation. Finally, let's mention that you can take a look at the changelog of the new version in detail here.
