Summary
=======

* New namespace

  :mod:`mhi.pscad` replaces `mhrc.automation`
  
* Embedding of Python inside PSCAD

  * An external Python environment is no longer required.
  
    Python scripts may be executed from within the PSCAD application itself.
    External execution of scripts remains supported,
    and remains essential for debugging.
  
* Communication with PSCAD is no longer using XML fragments

  * Commands returning XML fragments as results have been removed

Deprecated Methods
==================

* The `Workspace`, `KeyStroke` and `Mouse` proxies have been removed;
  and their methods moved into the :class:`PSCAD <reference/PSCAD>` class. 

* All commands which returned XML fragments from the communication protocol
  between PSCAD and the Automation Library have been removed,
  since that communication protocol has been replaced.
