“Although point releases are often overlooked by users, because they aren’t major upgrades, this time around you should certainly run the upgrade immediately.”
The biggest reason is that this point release combines all of the security fixes and improvements that have been added since the initial release of Jammy Jellyfish. So, if you haven’t bothered to upgrade Ubuntu 22.04 since you first installed it, which you should have been doing all along, this point upgrade will add everything you’ve missed in one fell swoop. One of the biggest upgrades for end users will be the ability of 20.04 users to upgrade to the latest release without having to touch the command line. At some point, users of 20.04 will see an upgrade prompt on their desktops, allowing them to easily make the jump to 22.04.1. This is a big deal because previously such upgrades would have required running several commands. That means no more:
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y
sudo do-release-upgrade -y
Another point release found in 22.04.1 is GNOME 42, which features a new enhanced dark mode and switches to Wayland by default, with the inclusion of Xorg for unsupported hardware.
