Pytransitions

Release 0.7.0 is a major release with fundamental changes to the diagram extension. It also introduces an intermediate `MarkupMachine` which can be used to transfer and (re-)initialize machine configurations.

- Feature 263: `MarkupMachine` can be used to retrieve a Machine's dictionary representation
- `GraphMachine` uses this representation for Graphs now and does not rely on `Machine` attributes any longer
- Feature: The default value of `State.ignore_invalid_triggers` changed to `None`. If it is not explicitly set, the `Machine`'s value is used instead.
- Feature 325: transitions now supports `pygraphviz` and `graphviz` for the creation of diagrams. Currently, `GraphMachine` will check for `pygraphviz` first and fall back to `graphviz`. To use `graphviz` directly pass `use_pygraphiv=False` to the constructor of `GraphMachine`
- Diagram style has been overhauled. Have a look at `GraphMachine`'s attributes `machine_attributes` and `style_attributes` to adjust it to your needs.
- Feature 305: Timeouts and other features are now marked in the graphs
- Bugfix 343: `get_graph` was not assigned to models added during machine runtime

- Bugfix 314: Do not override already defined model functions with convenience functions (thanks Arkanayan)
- Bugfix 316: `state.Error` did not call parent's `enter` method (thanks potens1)

- Bugfix 301: Reading `Readme.md` in `setup.py` causes a `UnicodeDecodeError` in non-UTF8-locale environments (thanks jodal)

Release 0.6.7 is identical to 0.6.6. A release had been necessary due to 294 related to PyPI.

- Bugfix: `HierarchicalMachine` now considers the initial state of `NestedState` instances/names passed to `initial`.
- Bugfix: `HierarchicalMachine` used to ignore children when `NestedStates` were added to the machine.
- Bugfix 300: Fixed missing brackets in `TimeoutState` (thanks Synss)
- Feature 289: Introduced `Machine.resolve_callable(func, event_data)` to enable customization of callback definitions (thanks ollamh and paulbovbel)
- Feature 299: Added support for internal transitions with `dest=None` (thanks maueki)
- Feature: Added `Machine.dispatch` to trigger events on all models assigned to `Machine`

- Feature 287: Embedding `HierarchicalMachine` will now reuse the machine's `initial` state. Passing `initial: False` overrides this (thanks mrjogo).
- Bugfix 292: Models using `GraphMashine` were not picklable in the past due to `graph` property. Graphs for each model are now stored in `GraphMachine.model_graphs` (thanks ansumanm).
