-* Fix replacing of previous certificate based on thumbprint matching
-* Fix to ignore stale option selections if Auto deploy/auto-binding selected
-* Various fixes and updates
-
-> **Notes regarding binding behaviour changes:**
->
-> Previously the app could try to enable SNI for a Static IP binding (based on the user's settings) this is no longer attempted.
->
-> Additionally if you had specified settings for the default IP of new bindings but switched back to Auto, the specific binding IP/port etc may still have been used for new bindings, this is no longer the behaviour.
->
-> If you have an existing http binding with a static IP this will be used if no hostname has been specified (all static IP SSL bindings carry a risk of binding conflicts, using SNI and specific hostnames is recommended).
->
-> If you require administrative control of https bindings you should select an option other than Auto under Deployment and Binding Add/Update should be set to Update only.
