- version update to 0.8.0
- Feature: `HierarchicalMachine` has been rewritten to support parallel states. Please have a look at the ReadMe.md to check what has changed.
+ The previous version can be found in `transitions.extensions.nesting_legacy` for now
- Feature: Introduced `AsyncMachine` (see discussion #259); note that async HSMs are not yet supported
- Feature #390: String callbacks can now point to properties and attributes (thanks @jsenecal)
- 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
