Compatibility Notes

This release requires Python 3.8 at the minimum. It is now using some language features introduced in 3.7 and a newer setuptools dependency that itself needs 3.8. A big benefit from this is better annotations for type checkers, now advertised through a py.typed marker. These are far from complete though and the library code itself still fails on many static typing checks.

The lower-level python-can library dependency (version 4.4.0) introduced an incompatible change, which is worked around in this release:

• Implement abstract method can.Listener.stop() in MessageListener by @acolomb in #422

Enhancements

• Support of custom can.Bus implementations to the Network class by @vongostev in #404
• 24 bit support by @raffi-g in #406
• Implement the remaining canopen datatypes by @sveinse in #440
• Mirror some OD access API to the SdoBase / SdoVariable classes by @acolomb in #423
• Implement equality operator for SdoAbortedError by @acolomb in #424
• Make pause after sending SDO request configurable by @sveinse in #429
• Fixup RETRY_DELAY on SDO send by @sveinse in #435
• Add support for using dot (.) to get subobjects from the OD by @sveinse in #426
• objectdictionary: Use node_id from DCF if not provided by @thesummer in #350
• Add codecov support (fixes #366) by @sveinse in #367

Bug Fixes

• objectdictionary: Fix incorrect ParameterValue when export_dcf by @meifonglow in #417
• SDO client fixes by @samsamfire in #408
• Ignore the most significant bit in PDO mapping lengths by @acolomb in #421
• Revert "change missing Baudrate to BaudRate" by @hepr-skylotec in #452
