Starting with OpenShift Container Platform 4.20 the Red Hat Operator catalogs moved from OperatorHub to the software catalog in the console [1].

The documentation for OpenShift Logging versions that are supported on OCP 4.20 and newer [2] needs to be updated so that the sentences like:

In the OpenShift Container Platform web console Administrator perspective, go to Operators  OperatorHub.

are including a variation for guiding the user on how to find the former OperatorHub, like for example:

In the OpenShift Container Platform web console Administrator perspective, go to Operators  > OperatorHub (Ecosystem > Software Catalog for OCP 4.20 and newer).
