See the following advisory for the RPM packages for this<br>release:<br><a href="https://access.redhat.com/errata/RHSA-2020:5119" target="_blank">https://access.redhat.com/errata/RHSA-2020:5119</a> Space precludes documenting all of the container images in this advisory.<br>See the following Release Notes documentation, which will be updated<br>shortly for this release, for details about these changes:<br><a href="https://docs.openshift.com/container-platform/4.5/release_notes/ocp-4-5-release-notes.html" target="_blank">https://docs.openshift.com/container-platform/4.5/release_notes/ocp-4-5-release-notes.html</a> This update fixes the following bug among others:<br><li> Previously, the Prometheus swagger definition contained a `$ref` property which could not be resolved. This caused a runtime error to occur when using the Prometheus operand creation form. This was fixed by adding a `definitions` property to schema returned by the `definitionFor` helper function so that the `$ref` property can resolve. There are no longer runtime errors when using the Prometheus operand creation form. (BZ#1885228)</li> You may download the oc tool and use it to inspect release image metadata<br>as follows:<br>(For x86_64 architecture)<br>$ oc adm release info<br>quay.io/openshift-release-dev/ocp-release:4.5.20-x86_64<br>The image digest is sha256:78b878986d2d0af6037d637aa63e7b6f80fc8f17d0f0d5b077ac6aca83f792a0<br>(For s390x architecture)<br>$ oc adm release info<br>quay.io/openshift-release-dev/ocp-release:4.5.20-s390x<br>The image digest is sha256:372d9aea634d36704d8500a2f940edb3867bfde14c0e5aa19534ea5ac90083d4<br>(For ppc64le architecture)<br>$ oc adm release info<br>quay.io/openshift-release-dev/ocp-release:4.5.20-ppc64le<br>The image digest is sha256:030d8323cce90de6bc7ad4119ebb7f000bde06e742f6923faf76707ffe85634a<br>All OpenShift Container Platform 4.5 users are advised to upgrade to these<br>updated packages and images when they are available in the appropriate<br>release channel.
