+    There will now be a warning if a user submits a job that is predicted to 
+    exceed their job execution time monthly quota of 10 minutes. 
+    This only applies to jobs run on real hardware in the instance ``ibm-q/open/main``. 
+    If the job does end up exceeding the quota, it will be canceled.
