Added support for OPC Security Interface version 1.0 and fixed critical bugs.
New Features: Improved security options - The OPC Security Interface version 1.0 is now supported, which gives the option of using NT Security or OPC private security.

Fixes: Correctly handles OPC HDA servers - that do not send a time along with a status.
Service Pack
PI Interface for OPC HDA
1.4.2.35
2011-08
This release addresses important bug fixes.
Rare, potential data-loss problem fixed – If the PI Server connection was lost during interface startup, the interface might fail to load all of its points.  This potential problem exists in UniInt version 4.5.0.59 and 4.5.1.4, affecting version 1.4.1.28 of this interface.  This has been corrected in this version of the interface now built on version 4.5.2.0 of UniInt. Memory Leak fixed – A memory leak that occurred when using string tags and when reading data from the HDA Server has been fixed.
