 ### Breaking changes
 
+* The optional `guest-agents` group, previously available within both the *Minimal Install* and *Custom Operating System* base environments in anaconda, is no longer available for selection as additional software for those environments. If you require the `guest-agents` group, it is available in either the *Server* or *Server with GUI* base environments. If you install *Minimal Install* or *Custom Operating System* and still want guest-agents, you can do so by installing the package target directly in Kickstart, or by installing it with DNF after installation has completed (i.e., dnf install @guest-agents).

 #### Live Images
 
 * The KDE live image for Rocky Linux 8.9 had problems during the testing phase. For this, we will be providing the older 8.8 images until we can build and provide a working image.
