Ubuntu 21.04 “Hirsute Hippo” Released

Today Canonical has released its latest version of the operating system, Ubuntu 21.04. Ubuntu 21.04 codenamed “Hirsute Hippo” packs with some cool new features and a lot of improvements over its predecessor Ubuntu 20.10.

Before users upgrade the current Ubuntu installation to Hirsute Hippo, it is important to note that Ubuntu 21.04 is a short-term support release. It’ll receive updates for 9 months, i.e. until January 2022.

What’s New In Ubuntu 21.04 “Hirsute Hippo”

Ubuntu 21.04 brings in some new features and a lot of improvements that will further improve the upcoming long-term support release.

Linux Kernel 5.11

Ubuntu 21.04 “Hirsute Hippo” ships with Linux Kernel 5.11 that itself contains additional support and a lot of updates. For example, Linux Kernel 5.11 added support for extended attributes in NFS, Btrfs performance and data recovery improvements, Intel Rocketlake and DG1 graphics support, and much more.

Smart Card Authentication

Smart cards are used everywhere, from Government offices to small companies. Smart cards add an additional layer of security by authorizing the person’s identity. Ubuntu 21.04 supports smart card authentication via pam_sss.


Another major change in Ubuntu 21.04 is the replacement of iptables with nftable. nftable is a subsystem of the Linux kernel that has great advantages over iptables. nftable is available in Linux kernel version 3.13 or greater.

Desktop drag-n-drop support

Ubuntu users will finally be able to drag and drop items to/from the file manager. A very small but useful feature that we missed in Ubuntu for a long time.

Power profile mode

Users will now be able to switch power profile mode from the system settings.
