      6.1.601.0
      2017/4/4
        
								
      • Enhanced the UA Client tag browser to import the components of complex variables. During import, the driver automatically imports components of complex variables when their data type derives from a supported built-in type or enumeration.
        • 
								
      • Enhanced browsing to allow importing all items as default data type.
        • 
								
      • Escaped spaces in OPC UA URLs caused issues for certain servers when connecting with security. Upgrading from KEPServerEX V6.0 to V6.1 requires re-issuing certificates to fix. Upgrading from V5.X to V6.1 re-issues the certificate automatically.
        • 
								
      • Resolved an issue where the driver did not re-subscribe to subscriptions that had timed out.
        • 
								
      • Resolved issue where the server could crash, resulting in "Invalid or missing user information" error messages until the server was re-installed or repaired. The issue could occur if there were multiple OPC UA Client driver channels attempting to connect simultaneously.
        • 
								
      • Transport layer disconnects are detected by the session watchdog, the timeout of which is now configurable. Enhanced reconnect logic to attempt to re-use sessions, subscriptions, and republish any missed data after a transport-layer disconnect.
        • 
								
      • Added support for UA Nano, Micro, and Micro Embedded UA Server profiles by eliminating the creation of monitored items for devices in 'Polled' mode. Devices in 'Polled' mode can now be configured to use registered or unregistered reads.
        •

        • 
								
      • Added a property to control whether an explicit read occurs after a write.
        • 
								
      • Resolved an issue where the UA Client driver did not correctly resolve internal tags like _System tags.
        • 
								
      • Fixed an issue where the server could crash which would result in "Invalid or missing user information" error messages until the server was re-installed or repaired. The issue could occur if there were multiple OPC UA Client driver channels attempting to connect simultaneously.
        • 
							
      
							
      5.21.112.0
      2016/8/16
        
								
      • Fixed a buffer overflow that could result in a crash.
        • 
								
      • Fixed an issue where the driver could delete monitored items immediately after creating them.
        • 
								
      • Fixed an issue in Polled Mode where all items were set to “Bad” quality if a keep-alive or data change was not received within the watchdog timeout. These only apply to Exception Mode and are not required for Polled Mode.
        • 
							
      
							
      5.20.396.0
      2016/5/3

        • 
								
      • Improved driver to prompt the user to trust a connection to the UA server when creating an initial connection using security if the certificate is not yet trusted.
        • 
							
      
							
      5.19.467.0
      2015/10/20
        
								
      • Enhanced Automatic Tag Generation for a device object while one or more clients are actively connected.
        • 
								
      • Resolved an issue that could cause the client to receive a newly written value, then a stale cached value, before receiving the new value again.
        • 
								
      • Resolved an issue where the posted error message was not representative of the actual cause of the error.
        • 
								
      • Resolved an issue that caused tag import to hang while loading large branches of tags.
        • 
							
      
							
      5.18.673.0
      2015/8/17
        
								
      • Upgraded OpenSSL (open source library) to version 1.0.2d to address security vulnerabilities pertaining to certificate validation.
        • 
							
      
							
      5.18.662.0
      2015/6/23
        
								
      • The driver no longer creates subscriptions and monitored items for inactive tags. This allows the driver to act in a cold redundancy mode when used with the Media Level Redundancy plug-in.
        • 
								
      • Increased time for UA clients to disconnect when shutting down to allow for proper shutdowns.
        • 
								
      • Changed the driver to request both the server and source timestamps from the UA server. The driver uses the source timestamp supplied by the UA server if it is available. If it is not available, the driver uses the UA server timestamp. If that is not available, the driver sets the timestamp to the current system time.
        • 
								
      • Fixed an issue to allow importing a tag branch containing a tag with an unsupported data type.
        • 
							
      
							
      5.17.495.0
      2015/2/24
        
								
      • Enhanced the driver to reconnect the UA session after encountering an invalid Session ID error.
        • 
								
      • The Device _Error flag is now set if the driver is unable to connect on the initial connection.
        • 
							
      
							
      5.16.722.0
      2014/10/21
        
								
      • Changed the driver to pass through source timestamp to tags instead of server timestamp. The timestamp will not be updated if the source timestamp is not provided.
        • 
							
      
							
      5.15.588.0
      2014/9/23
      
							
        
								
      • The driver now passes the source timestamp instead of the server timestamp to tags.
        • 
							
      
							
      
							
      5.15.585.0
      2014/7/22

        • 
							
      
							
      
							
      5.14.491.0
      2014/2/18
      
							
        
								
      • Fixed a memory leak caused by unremoved items in a subscription. The leak occurred for Subscriptions using the "Poll" Update Mode.
        • 
							
      
							
      
							
      5.13.191.0
      2013/10/15
      
							
        
								
      • Resolved an issue where the driver failed to import tags if the data type returned by the target server was VT_EMPTY.
        • 
							
      
							
      
							
      5.10.205
      2012/11/13
      
							
        
								
      • Fixed an issue where the Default data type on a Static Tag using a dynamic address had Bad Quality.
        • 
							
      

							
        
								
      • Fixed an exception that would occur when invalidating tags while unloading the driver.
        • 
							
      
							
      
							
      5.9.170
      2012/6/26

      5.3.118.0
      2010/6/9
      
							
        
								
      • The driver now reports a value, quality, and timestamp for invalid tags (tags that can't be added to the remote server). Previously we would keep attempting to read the tags, expecting an initial update. In the case that the tag is invalid we won't receive an update, and should report the tag is BAD.
        • 
								
      • Fixed issue where the requested data type was not being honored when providing tag updates on monitored items.
        • 
								
      • Fixed a bug where the password was not cleared in the decryption logic if the password was empty. This caused the runtime and the configuration to get out of sync with channel passwords.
        • 
								
      • The performance of Auto Tag Generation has been enhanced.
        • 
								
      • Fixed an issue where we fail to connect to our own UA server if we are using a username/password and no security.
        • 
								
      • The client driver now places the server certificate in the rejected store if it fails to connect with security. In the configuration we also display a message box that allows the user to trust an untrusted endpoint.
        • 
								
      • Added synchronization and error checking for session read and write callbacks. It was possible to get an invalid subscription handle in the callback.
        • 
								
      • The driver now removes all items from the underlying server when the UA Client's device is configured as disabled.
        • 
								
      • Fixed an issue where the UA Client Driver returned an invalid read value when an item did not receive an update from the UA Server. We now continue to process the read request until we have a valid return value.
