Breaking Changes

  • The can.BitTiming class was replaced with the new can.BitTiming and can.BitTimingFd classes (#1468, #1515).
    Early adopters of can.BitTiming will need to update their code. Check the documentation for more information. Currently, the following interfaces support the new classes:

    There are open pull requests for kvaser (#1510), slcan (#1512) and usb2can (#1511). Testing
    and reviewing of these open PRs would be most appreciated.
