OPC HDA .NET Server Toolkit Version Log

Aug-24-2017   V6.0.1
The Server object release did release Browser that were not released by the client. This could cause access violation errors if the client released the Browser object after the Server object. To prevent this, this server doesn't release the Browser objects anymore. As a consequence there is the possibility for memory leaks if the clients fail to release the Browser objects.
