Ubuntu 21.04 Hirsute Hippo – What’s New
Kernel 5.11
Ubuntu 21.04 features the Linux Kernel 5.11 which brings a huge set of hardware support and performance improvements across processor, graphics, and storage modules. Major updates in this Kernel include AMD Zen1/Zen2/Zen3 PowerCap RAPL (Runtime Average Power Limiting) Support, Software Guard Extensions support for Intel processors, etc. You can check out our coverage of the Linux Kernel 5.11 feature overview here.
Home Directory is now private
After more than a decade of discussion, finally, the Ubuntu team decided to change the user home directory permission. That means the home directory is not world-readable anymore. The permission changes from 755 to 750. As Ubuntu becomes more popular across desktops, servers, clouds – there is a high chance of shared systems used by multiple users and very few admins. So, in those cases, it is necessary to take this step, now. More details here.
Wayland by default
It’s time finally. Wayland-related improvements were landing in Ubuntu for some time. And it was not enabled by default. Finally, the Ubuntu team decides that it is safe to enable it as a default shell. So, in the login screen, you can see the Ubuntu Wayland option is set as default and not the Ubuntu on Xorg option. Although it is set to default, be cautious that things might breaks – especially if you have Nvidia hardware and use screencasting and other related applications. However, with this, it is expected that you get better performance and security from your display server.
Updated Applications
Ubuntu, by default, features GNOME desktop environment which comes with a list of native apps. Alongside, Ubuntu pre-loads certain necessary applications. This release features the older GNOME 3.38 and not the revamped GNOME 40. But the native GNOME apps having mixed versions – 3.38 and 40.0 both. Here’s a summary of the applications and their versions.

New Icons, UI refinements, and dark mode
Icons in default Yaru theme refreshed in this release. The default application icons such as LibreOffice modules are changed to give it a more professional look.
Few UI changes also land in this release. They are very hard to notice though. For example, the notification dot is now a bell icon. The system tray arrows are thinner. The input boxes on the desktop have a colored border.

Ubuntu comes with three themes – light, dark and standard. With this release the dark mode is set to default for desktop menus. For example, the calendar in the notification area is now having the dark mode set by default.
