+        Ensemble was not power-ed up and able to communicate.
+        
+        Files modified: drvEnsembleAsyn.cc
+
+2) Aerotech Ensemble EOT limit switch status was not available except via an
+        Ensemble fault condition.  With this release the status of the EOT
+        limit switches are always available.
