+- CVE fixes and adoption of OpenSSF scorecard on key repositories
+    
+### Migration consideration
+
+As part of the changes to the metrics to add the new `namespace` label, we changed from using a Prometheus `Counter` to a `CounterVec`. As a result there is no default value of `0` on the counter, which means when users query for a specific metric such as `ff_message_rejected_total` it will not be available until the `CounterVec` associated with that metric is incremented. This has been safely added as part of a patch release and determined to be an easy upgrade for SRE monitoring these metrics.
