Ubuntu 20.04.5 LTS is a freshly-spun install image composed of Ubuntu 22.04 LTS, along with all major security patches, bug fixes, and app updates since Ubuntu 20.04.4 LTS was released in February.
Install media must be refreshed periodically to minimize the number of post-install updates a user has to install after (or during, if that is an option).
It is not necessary for you to reinstall anything if you already run Ubuntu 20.04 LTS and have installed all updates as/when released. You’re not missing anything; you have everything included in these new images, and you have it already.
This new ISO is the one to use if you don’t already use Ubuntu 20.04 LTS, but plan to.
The main attraction of this point release is Linux 5.15, with the kernel ported over from Ubuntu 22.04. It introduces NTFS drivers, an integrated SMB server, tweaks to EXT4 (Ubuntu’s default filesystem), and support for power profiles.
GNOME Shell 3.36.8, LibreOffice 6.4.7.2, and Mozilla Firefox 104 are also bundled with the new ISO.
