New Fixes in This Release

1. This fix extends the functionality introduced by Fix #LA1059 so that the fix also takes effect for connections to Version 7.5 VDAs made from Windows 8.1 endpoints.

   From the description of #LA1059:

   With this enhancement, removing a smart card reader from an endpoint results in the same behavior as removing a smart card from an endpoint. As a result, with the VDA smart card policy configured to "Lock Workstation," removing the reader disconnects the session, effectively locking the VDA.

   To enable the fix, set the following registry keys:

   • HKEY_LOCAL_MACHINE\Software\Citrix\SmartCard
     Name: ReaderUnpluggedDetectEnable
     Type: REG_DWORD
     Value: Non-zero value
   • HKEY_LOCAL_MACHINE\Software\Citrix\SmartCard
     Name: ReaderUnpluggedDetectPollingInterval
     Type: REG_DWORD
     Value: 5 to 60 seconds (default polling interval is 10 seconds)
