Bug Fixes and Enhancements
TFS 21482 - AlarmEvents with a state of normal returned in GetAlarmEvents response for EWS
GetAlarmEvents has been changed to not return any alarms in the normal state.

TFS 21483 - Incorrect Timestamp information provided for AlarmEvents not in the Active state
Alarm time stamps are now updated to reflect the true time stamp of occurrence for all state changes (active, drop out, acknowledge).

TFS 21484 - Unable to filter AlarmEvents by Type via EWS
Alarms are now filtered based on type. 

TFS 21485 - Unable to successfully acknowledge alarms via EWS
In some situations, EWS would not acknowledge alarms correctly.  This behavior has been fixed.

TFS 21486 - Unable to filter alarms using the PriorityTo and PriorityFrom fields
EWS did not observe the priority field correctly.  This has been addressed and the minimum allowable priority has been set to 1 (to exclude non-alarm objects in the PowerSCADA alarm database).

TFS 21557 - PowerSCADA projects, including the starter project, PLS_Include, and PLS_Example, need to be upgraded to support new dbf schemas
PowerSCADA projects have been upgraded to the latest dbf schemas.  If there are existing projects created from the starter project, set [CtEdit] Upgrade = 1 in the Citect.ini file using the Setup Editor, then restart PowerSCADA Studio.

TFS 21564 - Alarm Proxy does not show the analog alarm states
Alarm Proxy now reports the analog alarm states (HIGH HIGH, HIGH, LOW, LOW LOW) instead of ON / OFF.

TFS 21566 - If a csv file has been selected in the IO Device Manager that does not exist, the application throws a runtime exception.
A message is displayed if the file does not exist.

TFS 21569 - On large systems with 200k configured alarms, the GetAlarmDefinitions call in Alarm Proxy is slow and causes ENM to timeout.
Performance issue in alarm proxy has been resolved.

TFS 21649 - When the Core Service Host adds and removes devices, it may loose the original Ids.
Core Service Host now keeps a device chronicle.  When the device is removed and then later added, the Id will remain the same.
