Ubuntu 20.04.4 LTS has been released. You may already have the updates if you are running 20.04 but it’s always good to ensure you are up to date.
Linux 5.13 is the big lure of this point release, carried over from October’s Ubuntu 21.10 release. Linux 5.13 introduces a bunch of tweaks including better EXT4 support, a new cooling driver for modern Intel CPUs, and better support for peripherals including the Apple Magic Mouse 2 and the GK6X mechanical keyboard.
This update also includes GNOME Shell 3.36.8, LibreOffice 188.8.131.52, and Mozilla Firefox 97.
