1.6.6 - Backward incompatible change in ruamel.yaml

Prepare 1.6.6

1.6.5 - Drop support for Python 3.5 and 3.6 (and fix issue with ruamel.yaml)

1.6.5?

1.6.4

Fixed invalid output of export_to_plantuml if statechart_preamble is enabled, with plantuml-1.2022.12+ (#119).

Fix remove_state

Statechart.remove_state no longer resets all initial states and all history states (#110, Rigó Ernő).

Enable Python 3.9 compatibility

    (Added) Support for Python 3.9.
    (Fixed) Remove deprecated import from collections (#101).
    (Fixed) Remove deprecated threading.isAlive used in sismic.runner.AsyncRunner.

Fix installation issue due to typing

Remove dependency to typing since it is no longer required for Python 3.5 and prevents the installation of Sismic.

History state memory

• (Added) Arrows to represent initial memory of an history state for sismic.io.export_to_plantuml (#96).
• (Fixed) Issue preventing initial memory to be defined for history states (#95).

Thanks to @Zinoex for these changes!

sismic-plantuml

• (Added) A sismic-plantuml command-line utility to access sismic.io.export_to_plantuml.

1.4.2

Transitions are no longer duplicated when calling copy_from_statechart (see #91 & #92), thanks to Jan Wouter Versluis!

1.4.1

The internals required to expose time and event-related predicates in a PythonEvaluator are moved
to the Interpreter instead of being handled by context providers. This eases the implementation by other
code evaluators of uniform semantics for these predicates. This change does not affect Sismic public API.
