Changelog¶

Version numbers are based on the release date (Y.M.D).

24.3.4¶

Improve time/date intervals:
- Accept microseconds in time specifications. However, a microsecond precision cannot be expected from an asyncio based Python program.
- Accept ISO 8601 time/date strings. (This feature is based based on Python’s support of ISO formats which was quite limited in versions prior to 3.11.)
- Introduce new endpoint separator and interval delimiter in order to solve ambiguities. The old syntax remains supported.
- Rewrite time/date related functions using the standard datetime module wherever possible.
- Rewrite the cron internal service. An issue with the schedule reload was found and fixed during the rewrite.
Enhance the support for durations with units.
Remove support for Python 3.8.
Add latest Python 3.12 to the list of compatible versions.
Improve compliance with the mypy type checker.
Put pylint configuration into the pyproject.toml file.

23.8.25¶

Make interfacing with external systems easier:
- In run() start supporting tasks after the simulation task.
- Add ExtEvent for events received from external systems. This implies further changes:
  - The existing Event should be used for internally generated events only.
  - SBlock.event() should not be used as an event entry point for external events.
  - The shortcut SBlock.put() is deprecated because SBlock.event() lost its importance.
Document the attributes Event.dest and Event.etype (also present in ExtEvent).
Improve the code compliance with the mypy static type checker.

23.2.14¶

Add new syntax in FSM.EVENTS.
Deprecate the use of iterators to specify multiple events, multiple event filters or a group of inputs.
Small code improvements.
