First if you already have Rock/OMLx 4.3 installed there is no need to install from these ISOs. If you keep your system up to date you will have what these ISOs provide.
These are a snapshot of Rock/OMLx 4.3 repositories with about 120+ upgraded packages plus about 10 new packages installed as dependencies. These are mostly bug fixes and security upgrades. One of the upgraded packages is
kernel-release-desktop-5.16.13-1. People wanting to do a fresh install may use these snapshots thereby avoiding needing these updates.

$ sudo dnf clean all ; sudo dnf up
