All notable changes to this project will be documented in this file.

• socketcan_vcan python-can interface (Linux) for virtual interfaces (vcan) that preserves hardware timestamps.

• send() now transmits messages with is_rx=False (previously ignored by the device as transmission acknowledgements), e.g. messages forwarded from SocketCAN, or transmitted messages replayed from log files.

• README.md is now shipped inside the installed package (python_can_cansub/README.md)

• Supported device API version changed from 04.00 to 05.00.

• max_device_time_skew: device/host clock skew (s) tolerated before setting the device clock on open (None=never).
• receive_own_messages: receive the messages transmitted by the bus itself (default False).

• Supported device API version changed from 03.00 to 04.00.
• The device hostname is now resolved only once on bus open, reducing connection time.
• data_bitrate is now optional. When omitted, transmissions of FD frames are rejected.
• Updated shutdown sequence (using DELETE on the websocket resource after shutdown_timeout timeout).

• server_cert: the server certificate is now always verified against the built-in CANsub root certificate. When connecting via an IP address, certificate hostname verification is automatically disabled (certificate chain verification remains active).

• server_cert: path to the server certificate (.crt file).
• client_cert: tuple of paths to the client certificate and key (.crt, .key), used for TLS mutual authentication.
• Warning when devices with unsupported API versions are found.

• Supported device API version changed from 02.00 to 03.00.

• CANSUB_ROOT_CERT: path to the CANsub root certificate.

• Transmit sequences (on the device) are deleted on bus open.

• CyclicSendTask with duration=None now working.
