v0.7.0

Date: 2026-11-06
Previous release: v0.6.0

Container contract 1.4: additions only, every v0.6.0 consumer keeps working.

Added

• The version document says whether the image is an independent
  implementation (independentEngine); every adapter here declares true,
  and results.json takes independent from it.
• OT Fabric's own stack, go-canbus, behind the same contract:
  ghcr.io/otfabric/canbus-interop-otfabric (adapter otfabric), so other
  stacks can test against it. It is not a reference and not in this release:
  the manual Own stack (go-canbus) workflow builds it from the latest
  go-canbus release, tests it against the reference images of the latest
  release and publishes it under go-canbus versions
  (own/go-canbus/README.md).
• scripts/lib.sh (image_of, ADAPTER_IMAGE_<adapter>) and
  scripts/interop.sh <adapter>..., the entry point of the cross-stack
  self-test (make interop; make selftest stays as its alias).
• The dbc suite checks any further codec against both oracles: each result
  must equal that of cantools or canmatrix.
• REQUIREMENTS.md (R1, repository isolation), checked by CI.

v0.5.0

Date: 2026-10-28
Previous release: v0.4.0

Container contract 1.3: additions only, every v0.4.0 consumer keeps working.

• CAN XL (canutils): frame documents
  marked "xl": true (priority, VCID, SEC and RRS flags, SDT, acceptance
  field, 1..2048 data bytes), --xl on send, receive and capture,
  capability xl. can-utils v2025.01's cansend and candump carry the frames
  on an interface with the CAN XL MTU, passing VCIDs through; this needs
  Linux ≥ 6.9 (cansend refuses CAN XL interfaces without
  CAN_RAW_XL_VCID_OPTS). The other adapters refuse --xl as
  unsupported (socketcanrs now recognises --xl to do so rather than
  rejecting an unknown flag).
• Fixture fixtures/frames/xl.jsonl: six CAN XL frames (priorities 0
  and 0x7FF, SEC and RRS, SDT, AF, VCIDs 0x42 and 0xFF, 1 to 2048 bytes).
• Self-test suite xl, on vcanxl0 (mtu 2060, created by make vcan):
  the fixture between every pair with the feature, CAN XL frames hidden from
  a receiver without --xl, --xl on an interface without the CAN XL MTU
  (exit 4), refusal by adapters without the feature (exit 2).
• canutils receive and capture count the frames they accept instead of
  using candump -n: candump also counts CAN FD and CAN XL frames that a
  receiver without --fd or --xl drops, so such a receiver could end
  with fewer frames than asked for. candump now runs with -L (flushed log
  lines on stdout); capture writes the accepted lines.

v0.4.0

Date: 2026-10-28
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.

v0.2.0

Date: 2026-10-28
Previous release: v0.1.0

Container contract 1.1: additions only, every v0.1.0 consumer keeps working.

• log-convert (pythoncan): CAN traces through python-can 4.6.1's own
  readers and writers: Vector ASC, Vector BLF, PEAK TRC, CSV, candump, and
  the contract's frame documents (.jsonl, lossless). Capabilities
  logAsc, logBlf, logTrc, logCsv. What each format keeps is measured
  in docs/LOG_FORMATS.md: BLF is lossless; ASC, TRC,
  CSV and python-can's candump writer lose the frame kinds listed there.
  New fixtures fixtures/logs/: frames written by python-can as ASC, BLF
  and TRC with python-can's reading of each.
• ARXML: cantools and canmatrix decode and encode AUTOSAR 4 ARXML
  (--db *.arxml, capability arxml), canmatrix converts it to DBC. New
  fixtures fixtures/arxml/ (generated by scripts/gen-arxml-fixtures.py):
  Intel and Motorola signals, standard, extended and CAN FD frames, LINEAR,
  TEXTTABLE, SCALE_LINEAR_AND_TEXTTABLE and IDENTICAL compu methods, signed
  (2C) base types, init values. Both oracles agree on every vector. Neither
  applies a PDU's START-POSITION inside its frame (fixture
  pdu-offset.arxml, reported as known).
• Pins: cantools 45.1.0 → 45.1.1. New weekly Upstream workflow
  (scripts/latest-upstream.py): keeps the issue "Upstream releases: pins
  behind the latest" open while a pin or a base image digest is behind;
  never changes a pin.
• Self-test: suites dbc (now with the ARXML fixtures) and logs
  (new). scripts/chroot-run runs the exported image file systems with
  chroot where no Docker daemon is, and scripts/microvm-isotp.sh runs the
  ISO-TP suite in a virtme-ng microVM with a stock Ubuntu kernel: see
  TESTING.md.

v0.1.0

Date: 2026-10-27
Previous release: none

First release of canbus-interop.

• Container contract 1.0 (docs/CONTAINER_CONTRACT.md) and JSON Schemas 1.0.
• Images: canbus-interop-canutils (can-utils v2025.01; kernel CAN_RAW and
  CAN_ISOTP), -pythoncan (python-can 4.6.1), -socketcanrs (socketcan
  4.0.0), -scapy (Scapy 2.8.0), -pythoncanisotp (python-can-isotp 2.0.7),
  -cantools (cantools 45.1.0), -canmatrix (canmatrix 1.3.3), for
  linux/amd64 and linux/arm64.
• Fixtures: frames (standard, extended, remote, every FD length, ESI, error
  frames, a 2000-frame sequence), seven DBC databases with decode and encode
  vectors, a KCD network.
• Self-test on vcan: raw CAN pairs, filters, loopback, receive-own, error
  frames, multi-consumer, capture/replay, malformed input, interface
  down/up; ISO-TP kernel ↔ python-can-isotp; cantools ↔ canmatrix.
