+== New features
+
+git-lfs dependency update::
+* With this update, the `git-lfs` dependency in the Argo CD container image is updated to `v3.7.1`.
++

+
+[id="fixed-issues-1-17-3_{context}"]
+== Fixed issues
+
+Redis version update::
+* With this update, the Redis version included with {gitops-title} is upgraded to `v7.2.11`.
++
+link:https://issues.redhat.com/browse/GITOPS-8019[GITOPS-8019]
+
+GitOps Operator pulls images from registry.redhat.io::
+Before this update, when the `.spec.version` field was set in the Argo CD CR, the {gitops-title} Operator incorrectly pulled upstream images from `quay.io`. With this update, this issue is fixed. The {gitops-title} Operator pulls images from `registry.redhat.io` and only uses certified images from the Red Hat registry.
++
+link:https://issues.redhat.com/browse/GITOPS-7789[GITOPS-7789]
+
+Revised rolling update strategy for HAProxy deployment::
+Before this update, the `openshift-gitops-redis-ha-haproxy` deployment failed to upgrade on a three-worker node cluster due to a combination of pod anti-affinity rules and the update strategy. With this update, the {gitops-title} Operator revises the rolling update strategy to fix this issue.
++
+link:https://issues.redhat.com/browse/GITOPS-8033[GITOPS-8033]
+
+Added ingress permissions for successful reconciliation::
+Before this update, the {gitops-title} Operator failed to reconcile when `.spec.applicationSet.webhookServer.route.enabled` was set to `true` in the Argo CD CR. This issue occurred because the {gitops-title} Operator lacked the required ingress permissions for `config.openshift.io`. With this update, the {gitops-title} Operator includes the necessary permissions and reconciles successfully.
++
+link:https://issues.redhat.com/browse/GITOPS-8152[GITOPS-8152]
+
+Improved Redis HA startup reliability::
+Before this update, in the Redis high availability (HA) mode, the Redis config `init` container could hang for several minutes while detecting the master container, causing Redis pods to take a long time to become _Ready_. With this update, the master container detection logic includes a connection timeout, which prevents the `init` container from blocking and ensures a faster, more reliable Redis HA startup.
