+- Ability to "disable" a queue so that messages are not routed to it
 - Support JVM GC & thread metrics
 - Support for resetting queue properties by unsetting them in `broker.xml`
 - Undeploy diverts by removing them from `broker.xml`
 - Add `addressMemoryUsagePercentage` and `addressSize` as metrics
 
 #### Upgrading from older versions
 
-Make sure the existing queues have their parameters set according to the `broker.xml` values before upgrading.
+This is likely a rare situation, but it's worth mentioning here anyway. Prior
+to 2.14.0 if you configured a parameter on a `queue` in `broker.xml` (e.g.
+`max-consumers`) and then later *removed* that setting the configured value you
+set would remain. This has changed in 2.14.0 via ARTEMIS-2797. Any value that
+is not explicitly set in `broker.xml` will be set back to either the static  
+default or the dynamic default configured in the address-settings (e.g. via
+`default-max-consumers` in this example). Therefore, ensure any existing queues
+have all the needed parameters set in `broker.xml` values before upgrading.
