* https://issues.redhat.com/browse/OSSM-3025[OSSM-3025] Istiod sometimes fails to become ready. Sometimes, when a mesh contained many member namespaces, the Istiod pod did not become ready due to a deadlock within Istiod. The deadlock is now resolved and the pod now starts as expected.
23+
24+
* https://issues.redhat.com/browse/OSSM-2344[OSSM-2344] Restarting Istiod causes Kiali to flood CRI-O with port-forward requests. This issue occurred when Kiali could not connect to Istiod and Kiali simultaneously issued a large number of requests to istiod. Kiali now limits the number of requests it sends to istiod.
25+
26+
* https://issues.redhat.com/browse/OSSM-2335[OSSM-2335] Dragging the mouse pointer over the Traces scatterchart plot sometimes caused the Kiali console to stop responding due to concurrent backend requests.

* https://issues.redhat.com/browse/OSSM-2053[OSSM-2053] Using {SMProductName} Operator 2.2 or 2.3, during SMCP reconciliation, the SMMR controller removed the member namespaces from `SMMR.status.configuredMembers`. This caused the services in the member namespaces to become unavailable for a few moments.
2329

2430
Using {SMProductName} Operator 2.2 or 2.3, the SMMR controller no longer removes the namespaces from `SMMR.status.configuredMembers`. Instead, the controller adds the namespaces to `SMMR.status.pendingMembers` to indicate that they are not up-to-date. During reconciliation, as each namespace synchronizes with the SMCP, the namespace is automatically removed from `SMMR.status.pendingMembers`.

The `concurrency` field works when set with `ProxyConfig`. The `concurrency` field specifies the number of worker threads to run.
