Previous release: v0.3.0

Fixtures only: container contract 1.2 and every image are unchanged in
behaviour (rebuilt and re-tagged).

  • fixtures/arxml/multiplexed.arxml: two MULTIPLEXED-I-PDUs — a 4-bit
    Intel selector with a static part and three dynamic alternatives (one
    initial), an 8-bit Motorola selector with two — with decode vectors for
    every selector code plus an undescribed one, and encode vectors.
    Generated by scripts/gen-arxml-fixtures.py.
  • Oracle coverage. cantools 45.1.1 reads multiplexed PDUs (selector
    <frame>_selector1, alternatives multiplexed by SELECTOR-FIELD-CODE, the
    static part always present); canmatrix 1.3.3 reads only the selector. The
    self-test checks each oracle against three probe frames worked out by
    hand: arxml-multiplexed-cantools must pass, arxml-multiplexed-canmatrix
    is recorded as known. See docs/FIXTURES.md.
  • scripts/validate-fixtures.py follows multiplexed PDUs when it checks the
    encode vectors' signal names.

v0.3.0

Date: 2026-10-28
Previous release: v0.2.0

Container contract 1.2: additions only, every v0.2.0 consumer keeps working.

  • slcan interfaces (pythoncan): send and receive accept --interface slcan:<url>, python-can 4.6.1's slcan interface (LAWICEL ASCII, the
    protocol of CANable-type serial adapters) over a pyserial URL such as
    slcan:socket://127.0.0.1:20000. A consumer plays the adapter on a TCP
    port (go-canbus's slcan transport does) and checks frames both ways
    without a CAN interface. CAN FD as d/D/b/B records. slcan has no
    error state indicator, error frames, echo or filters: those requests end
    with exit 2 (unsupported). Capability slcan.
  • The pythoncan image adds pyserial 3.5 (BSD-3-Clause, pinned like every
    package).
  • The pythoncanisotp adapter gives its CAN socket a 1 MiB receive buffer:
    a 4095-byte message at STmin 0 (585 frames) overflowed the default one in
    a slow microVM (self-test mf-4095, intermittent).
  • Self-test suite slcan: two python-can slcan clients joined by a TCP
    relay exchange the standard, extended, remote, CAN FD and burst
    fixtures; ESI and error frames are refused.
