RELEASE NOTES
May 29, 2015

1. The OpenOPC Gateway Service includes a new feature that will automatically
   disconnect and close OPC client sessions that have become inactive.

Two Windows system environment variables control this feature:

OPC_INACTIVE_TIMEOUT specifies the number of minutes that a client is
allowed to remain inactive before the server closes its connection.

OPC_MAX_CLIENTS specifies the maximum number of clients that are allowed
to be simulatenously connected to the server. Once the max has been
reached additional client connection requests will not be refused.
Instead the server will automatically disconnect the client session
that's been inactive for the longest period of time in order ot make
space for the new client.

1. The OPC_GATE_HOST system enviornment variable has new features. If you
   set it equal to 0.0.0.0 then the Gateway Service will listen on all ethernet
   interfaces. But if you set it to a specific IP address then it will only
   listen on that interface. Note that on machines with multiple ethernet
   interfaces it may be necessary to set this to a specific IP address
   otherwise the service can fail to listen entirely.
2. New command line install script for Windows systems included in the
   zip file distribution of OpenOPC.
