v0.6.0

Date: 2026-10-29
Previous release: v0.3.2

Summary

Built on go-profinet v0.6.0 and released together with it and
profinet-interop v0.6.0: from this version the three share one version
number (there is no v0.4.x or v0.5.x of profinetctl). The examples cover
every command.

Changes

• go-profinet v0.6.0: PNIO error statuses of CMRPC name their cause ("AR
  UUID unknown", "state conflict", …) in error messages, for example a
  disconnect of an AR the device does not know.
• mrp status of a device without media redundancy (its read answers
  "invalid index") fails as unsupported (exit 6) with a clear message
  instead of the raw PNIO status.
• make examples-doc also shows hello listen while a device starts,
  alarms with the diagnosis that follows, mrp status and
  disconnect; docs/EXAMPLES.md on main is regenerated from this
  release's binary.
• SECURITY.md: 0.6.x supported; docs/exitcodes.md and
  docs/json-output.md name the mrp status case.

v0.3.2

Date: 2026-10-28
Previous release: v0.3.1

Summary

topology check speaks text, and the documentation was checked command
by command against the code.

Changes

• topology check with --format text writes one line per expected link
  (its verdict and what the ends report), the unexpected links and the
  unreachable stations; it printed the JSON report before.
• Stream events without detail (reparameterized that succeeded) end
  without a trailing space.
• docs/json-output.md: device info names module_ident_number and
  submodule_ident_number (as the code always did); disconnect and
  gsdml generate results; optional lists are omitted when empty.
• docs/exitcodes.md: exit 7 of gsdml check, gsdml gsdx and topology check; hello listen streams.
• README: the flags of discover, record write/im write in an IOCAR,
  lldp neighbors, topology, mrp status, io, and the AR flags of
  connect; GSDX inspection versus signature verification.
• SECURITY.md: 0.3.x supported; connect --param/--reparam/--mrp-role/ --peer-check/--assign-ip among the commands that change a device.
• make examples-doc also shows gsdml check, gsdml generate,
  topology check and connect --reparam; docs/EXAMPLES.md on
  main is regenerated from this release's binary.

v0.3.1

Date: 2026-10-28
Previous release: v0.3.0

Summary

Requires go-profinet v0.5.0 (MRP automatic manager, MRP verified against
the Linux kernel's bridge MRP).

Changes

• go-profinet v0.5.0: a device's unchanged state is no longer saved again,
  and mrp status of a go-profinet device configured as an automatic
  manager (MRA) shows the role it acts in.
• README: MRA cannot be set with --mrp-role (no PROFINET MRP_Role value).

v0.3.0

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

Summary

Requires go-profinet v0.4.0. connect --reparam re-parameterizes a
running AR; the limitations say what profinetctl does with MRP, shared
devices and system redundancy.

Changes

• connect --reparam SLOT:SUBSLOT:INDEX:HEX (repeatable) and
  --reparam-after (default 1 s): PrmBegin, the records, PrmEnd and the
  device's ApplicationReady while cyclic data goes on; a reparameterized
  event (with error when it failed) in the stream.
• README limitations corrected: profinetctl gives a multiport device its
  MRP role and reads its state, and expects a subset of modules on a shared
  device (it said "no MRP, no shared devices"); S2 is not exposed.
• go-profinet v0.4.0: an allocation-free AF_PACKET backend on Linux, stable
  LLDP neighbor indexes in the device's SNMP agent, and fixes (a second
  controller could be refused "out of AR resources").

v0.2.0

Date: 2026-10-27
Previous release: v0.1.2

Built on go-profinet v0.3.0
(release notes):
commands for the features of its software-only roadmap. No change to the
output or exit codes of existing commands.

• gsdml check FILE [--strict]: the full GSDML check, every issue with its
  severity (error, warning, unvalidated) and rule; exit code 7 on errors,
  with --strict on any issue.
• gsdml gsdx FILE: inspect a GSDX container (parts, relationships, core
  properties, signature metadata; signatures are not verified, PI's GSDX
  rules are members only), each GSDML part checked; --extract writes one
  part.
• topology check --link A/PORT=B/PORT | --expect FILE: verify the cabling
  against the expected links; exit code 7 when it differs.
• hello listen: stream the DCP Hellos of devices that announce themselves.
• mrp status: a device's MRP role, domain, ring state and ring ports.
• connect and the AR commands: --slot N expects only some modules
  (shared device), --peer-check PORT=STATION/PORT writes a peer check,
  --mrp-role client|manager|off writes the MRP records of a multiport
  device.
• JSON of the new commands in docs/json-output.md.

v0.1.2

Date: 2026-10-27
Previous release: v0.1.1

Built on go-profinet v0.2.0
(release notes).

• gsdml validate also checks that the input and the output data of every
  submodule fit an RT frame (1439 octets plus the provider status): a file
  that breaks it now has issues (exit code 7). Its JSON issues gain
  severity ("error") and rule ("structure", "reference" or
  "io-data-length"); see docs/json-output.md. The
  checked: line says so.
• The IO-Controller commands (connect, io, alarms) run on go-profinet
  v0.2.0's controller, whose state waits now return only after the state's
  callback. No other change to commands, output or exit codes.
• RELEASE.md in the otfabric release-notes format, checked by
  make release-notes-check and CI.

v0.1.1

Date: 2026-10-26
Previous release: v0.1.0

Built on go-profinet v0.1.2: AR state changes of a device in order, RPC
responses of many fragments no longer time out on a loaded host, BPF ports
return ErrClosed after Close. No change to commands, output or exit
codes.

v0.1.0

Date: 2026-10-26

First version, built on go-profinet v0.1.1.

• DCP discovery and commissioning: discover, identify, name get/set, ip get/set, signal, reset.
• Records and identification: record read/write, im read/write, diagnostics, device info, status.
• Topology: lldp neighbors, topology (PDRealData of every device).
• GSDML: gsdml inspect, validate, modules, submodules, generate.
• IO-Controller from a GSDML file or a go-profinet model: connect, ar, iocr, io status/monitor/statistics, alarms, disconnect.
• Text, table and JSON output with stable exit codes (docs/exitcodes.md, docs/json-output.md); verified against rt-labs p-net (docs/EXAMPLES.md).
