• Bugfix: Auto transitions are added multiple times when add_states is called more than once
• Bugfix: Convert state._name from Enum into strings in MarkupMachine when necessary
• Bugfix #392: Allow Machine.add_ordered_transitions to be called without the initial state (thanks @mkaranki and @facundofc)
• GraphMachine now attempts to fall back to graphviz when importing pygraphviz fails
• Not implemented/tested so far (contributions are welcome!):
  • Proper Graphviz support of parallel states
  • AsyncHierachicalMachine
