+==== Enhancements
+
+* In the bootstrap phase of the installation process, the Transport Layer Security (TLS) between the `metal3` `httpd` server and the node's Baseboard Management Controller (BMC) is enabled by default in {product-title} 4.18 and later. The `httpd` server is on port 6183 instead of port 6180 when TLS is enabled. Disable the TLS setting by adding 'disableVirtualMediaTLS: true' to the provisioning custom resource (CR) file that is created on the disk. (link:https://issues.redhat.com/browse/OCPBUGS-39404[OCPBUGS-39404])

+==== Bug fixes
+
+* Previously, the Prometheus remote-write proxy configuration was not correctly applied to the Prometheus user workload custom resource (CR), which caused communication and data collection problems in the cluster. With this release, the user workload monitoring (UWM) Prometheus configurations, including user workload Prometheus, correctly inherit the proxy settings from the cluster proxy resource. (link:https://issues.redhat.com/browse/OCPBUGS-38655[OCPBUGS-38655])
+
+* Previously, when running {op-system-first} in an active environment, the `rpm-ostree-fix-shadow-mode.service` systemd service that used to run caused that service to fail. With this release, the `rpm-ostree-fix-shadow-mode.service` systemd service does not activate when {op-system} does not run from an installed environment. (link:https://issues.redhat.com/browse/OCPBUGS-41625[OCPBUGS-41625])
+
+* Previously, an incorrect component import in the `SimpleSelect.tsx` file caused an undefined function `r` function in the `react-dom.production.min.js` file. This component caused error messages on the *Dashboards* and *Metrics* pages related to dropdown lists. With this release, the dropdown lists on the affected pages function correctly, eliminating the error message. (link:https://issues.redhat.com/browse/OCPBUGS-42845[OCPBUGS-42845])
+
+* Previously, an error in the rotation logic of the image pull secret controller's secret token caused a temporary, invalid token for authentication. As a consequence, the image pull process was disrupted. With this release, the updated image pull secret controller eliminates the period when the token is not valid while the token rotates. As a result, the image pull process is smooth and continuous. (link:https://issues.redhat.com/browse/OCPBUGS-54304[OCPBUGS-54304])
+
+* Previously, an error occurred in {hcp}-managed clusters because of the omission of the `shutdown-watch-termination-grace-period` setting in the `kube-apiserver` configuration. This error led to the unstable shutdown of applications in {hcp}-managed clusters. With this release, an update improves the shutdown process of applications in {hcp}-managed clusters, providing a grace period for the `kube-apiserver` configuration. During a shutdown, the application stability is improved and potential errors are decreased. (link:https://issues.redhat.com/browse/OCPBUGS-53404[OCPBUGS-53404])
+
+* Previously, an issue with the version of the `github.com/sherine-k/catalog-filter` element stopped, causing instability in the mirroring process. With this release, the `github.com/sherine-k/catalog-filter` element in the `go.mod` file is updated, which solves the problem and ensures a stable and reliable mirroring process. (link:https://issues.redhat.com/browse/OCPBUGS-54727[OCPBUGS-54727])
+
+* Previously, an iteration counter increment omission in the `scrapeCache` setting led to an incorrect series count for subsequent scrapes. As a result, monitoring was interrupted and data could potentially be lost during the Prometheus scrape process. With this release, an update ensures uninterrupted monitoring, because Prometheus continues scraping and processing data while parsing errors.
