      * Previously, the reduction of the network queue did not work as expected for inverted rules such as `!ens0`. This happened because the exclamation mark symbol was duplicated in the generated tuned profile. With this release, the duplication no longer occurs so that inverted rules apply as intended. (link:https://issues.redhat.com/browse/OCPBUGS-35012[*OCPBUGS-35012*])
      __________
