Bump python-can from 4.3.1 to 4.6.1

[dependabot]

Bumps python-can from 4.3.1 to 4.6.1.

Release notes

Sourced from python-can's releases.

4.6.1

Version v4.6.1 - 2025-08-12

Fixed

• Fix initialisation of an slcan bus, when setting a bitrate. When using CAN 2.0 (not FD), the default setting for data_bitrate was invalid, causing an exception. (#1978)

v4.6.0

🚀 Highlights

• 🆕 New CLI tool: can_bridge — bridge two physical CAN buses in software via python -m can.bridge.
• 📡 Expanded protocol support:
  • 11-bit identifiers, remote frames, and error frames in the serial interface.
  • CAN FD support in slcan for CANable 2.0 devices.
  • Error message support in the socketcand interface.
  • Remote frame support in TRCReader.
• 🖥 Windows support: Added support for the udp_multicast interface on Windows.
• 🔔 Notifier improvements:
  • Track active Notifiers and use them as context managers.
  • New helper: Notifier.find_instances(bus) to discover active Notifiers.
• 🛠 Better CLI integration: Public functions can.cli.add_bus_arguments and can.cli.create_bus_from_namespace for downstream packages to easily configure and parse python-can bus options.

Added

• Add support for 11-bit identifiers in the serial interface. (#1758)
• Add context manager support and active instance tracking to Notifier, plus Notifier.find_instances(bus). (#1890)
• Add Windows support to udp_multicast interface. (#1914)
• Add FD support to slcan according to CANable 2.0 implementation. (#1920)
• Add support for error messages to the socketcand interface. (#1941)
• Add support for remote and error frames in the serial interface. (#1948)
• Add public functions can.cli.add_bus_arguments and can.cli.create_bus_from_namespace for creating bus command line options. Currently downstream packages need to implement their own logic to configure python-can buses. Now python-can can create and parse bus options for third party packages. (#1949)
• Add support for remote frames to TRCReader. (#1953)
• Mention the python-can-candle package in the plugin interface section of the documentation. (#1954)
• Add new CLI tool python -m can.bridge (or just can_bridge) to create a software bridge between two physical buses. (#1961)

🔧 Changed

• Allow sending Classic CAN frames with a DLC value larger than 8 using the socketcan interface. (#1851)
• Rename the gs_usb extra dependency to gs-usb. (#1945)
• New PEP 735 dependency groups lint, docs and test. (#1945)
• Update dependency name from zlgcan-driver-py to zlgcan. (#1946)
• Use ThreadPoolExecutor in detect_available_configs() to reduce runtime and add timeout parameter. (#1947)
• Update contribution guide. (#1960)

Changelog

Sourced from python-can's changelog.

Version v4.6.1 - 2025-08-12

Fixed

• Fix initialisation of an slcan bus, when setting a bitrate. When using CAN 2.0 (not FD), the default setting for data_bitrate was invalid, causing an exception. (#1978)

Version v4.6.0 - 2025-08-05

Removed

• Remove support for Python 3.8. (#1931)
• Unknown command line arguments ("extra args") are no longer passed down to can.Bus() instantiation. Use the --bus-kwargs argument instead. (#1949)
• Remove can.io.generic.BaseIOHandler class. Improve can.io.* type annotations by using typing.Generic. (#1951)

Added

• Support 11-bit identifiers in the serial interface. (#1758)
• Keep track of active Notifiers and make Notifier usable as a context manager. Add function Notifier.find_instances(bus) to find the active Notifier for a given bus instance. (#1890)
• Add Windows support to udp_multicast interface. (#1914)
• Add FD support to slcan according to CANable 2.0 implementation. (#1920)

• Update contribution guide. (#1960)

Fixed

• Fix a bug in slcanBus.get_version() and slcanBus.get_serial_number(): If any other data was received during the function call, then None was returned. (#1904)
• Fix incorrect padding of CAN FD payload in BlfReader. (#1906)
• Set correct message direction for messages received with kvaser interface and receive_own_messages=True. (#1908)
• Fix timestamp rounding error in BlfWriter. (#1921)
• Fix timestamp rounding error in BlfReader. (#1927)
• Handle timer overflow message and build timestamp according to the epoch in the ixxat interface. (#1934)
• Avoid unsupported ioctl function call to allow usage of the udp_multicast interface on MacOS. (#1940)
• Fix configuration file parsing for the state bus parameter. (#1957)
• Mf4Reader: support non-standard CAN_DataFrame.Dir values in mf4 files created by ihedvall/mdflib. (#1967)
• PcanBus: Set Message.channel attribute in PcanBus.recv(). (#1969)
