sparkplugb-interop v0.4.0
Date: 2026-11-06
Previous release: v0.3.1
Added
own/go-sparkplugb/and the manual workflow Own stack (go-sparkplugb): go-sparkplugb, OT Fabric's own stack, behind the container contract as an edge node (edge.Node) and as the primary host application (host.App), published asghcr.io/otfabric/sparkplugb-interop-otfabric:<go-sparkplugb version>and:latestfor others to test against. It is not an independent implementation (upstream.independentEngine: false) and not part of this or any release:manifest.jsondoes not list it.ADAPTER_IMAGE_<adapter>:scripts/smoke.shandscripts/interop.shtake an image from outside the release set (a-in the adapter name is a_in the variable).compose.yaml: a broker, a reference host and a reference edge node for local work, as in the other harnesses.
Changed
results.jsontakesindependent, and for an image outsideversions.yamlits licence and upstream name, from what the image says of itself.scripts/interop.shruns only the pairings with an adapter whoseupstream.independentEngineisfalse, when there is one among its adapters: the references were checked against each other already.- The R1 check of CI also covers
compose.yaml. - Contract 0.3: the DBIRTHs of a rebirth, on an NCMD or on
call rebirth, may come in any order, each device once, withseq1, 2, ...; fixture order is required of the first births only. Sparkplug 3.0.0 asks a rebirth for "a complete BIRTH sequence" and fixes no order among the DBIRTHs.scripts/interop.shchecks that. Every reference adapter already meets 0.2, which is stricter, so none changes; a consumer that checks the order of a rebirth's DBIRTHs should stop. tests/known-bugs.tsv: the entries for the pysparkplug host on the scalars fixture and the Tahu host on the baseline fixture also apply with theotfabricedge, which shows the same behaviour as the edges already listed.
The reference adapters and the fixtures do not change.

sparkplugb-interop v0.3.0
Date: 2026-11-01
Previous release: v0.2.2
Added
- Fixture
composite: integers inside the composite values of Sparkplug, DataSet cells, template parameters and members, and metric properties, at the limits of each type. Tahu, tahu-js and SparkplugNet run it as edges, Tahu, SparkplugNet and sparkplughost as hosts. pysparkplug has none of these values, and srad no DataSet: neither declares the fixture. - Contract 0.2:
DataSetandTemplateas datatypes, with object values, andpropertieson metrics, in fixtures and inmessageevents (docs/FIXTURES.md,docs/CONTAINER_CONTRACT.md). Consumers that run every fixture of an edge meet one more, and must read object values. make int-vectorsandtests/int-vectors.tsv: what each host makes of Int8 and Int16 wire values in both forms and in neither.- Known bugs: the SparkplugNet host drops metric properties, the Tahu host leaves out an alias-addressed Template whose members carry no datatype.
Changed
- The self-test compares documents with sorted keys.
Documentation
docs/COMPATIBILITY.md: the per-broker counts are from a run with the third update ofscalarsand withcomposite.

sparkplugb-interop v0.2.2
Date: 2026-10-31
Previous release: v0.2.1
Changed
- The Int8 and Int16 entries of
tests/known-bugs.tsvare reclassified as specification ambiguity. Sparkplug B 3.0.0 does not say how a negative value goes inint_value. The pairings that cannot work (the pysparkplug host with sign-extended edges, the SparkplugNet host with width-sized edges) stay recorded as known differences. No stack is labelled non-compliant for its form. - The
scalarsfixture has a third update that takes Int8 and Int16 to -128 and -32768. Consumers that run every update of a fixture run one step more.
Fixed
docs/COMPATIBILITY.md: tahu-js does not read both forms, only the harness adapter does; sparkplughost does not decode these values, its adapter does. The table of what each stack encodes and decodes is new.

sparkplugb-interop v0.2.0

Previous release: v0.1.0
Summary
Self-test results as the organisation's interop-result-v1.
Changes
Added
reports/results.json(interop-result-v1):scripts/interop.shwrites it whenREPORT_DIRis set, with stable IDs<fixture>.<step>, the broker and the digests.make interop-brokerswrites one per broker, under$REPORT_DIR/<broker>/. Onlypasscounts as passing; a run with no pass, or with a waiver that no longer reproduces, fails. Existing reports keep their shape. An intermittent entry that did not show is not listed as a waiver.tests/known-bugs.tsvhas a ninth column, the evidence URL pinned to the upstream version.

sparkplugb-interop v0.1.0
Date: 2026-10-27
Summary
First release: Sparkplug B 3.0.0 edge nodes and host applications of
independent implementations as multi-arch images with one container
contract, two fixtures, and pinned MQTT brokers to run them on.
Changes
Added
- Container contract 0.1 (docs/CONTAINER_CONTRACT.md):
edge,host,callover a control socket,print-capabilities,print-fixture,version; JSON Lines events, call result documents, fixed exit codes. - Fixtures
baseline(node with two devices, writable metrics, two updates) andscalars(all 14 scalar datatypes at their limits), with a JSON Schema and a validator for the cross-field rules. - Adapter images: Eclipse Tahu 1.0.21 (Java, edge and host), pysparkplug 0.6.1 (Python, edge and host), SparkplugNet 1.4.1 (C#, edge and host), srad 0.5.0 (Rust, edge and host), Eclipse Tahu sparkplug-client 3.2.4 (JavaScript, edge) and sparkplughost v0.4.0 (Go, host). See README.md.
- Broker pins: Eclipse Mosquitto, HiveMQ CE, EMQX and NanoMQ, by multi-arch digest in
versions.yamlandmanifest.json. - Self-tests:
scripts/smoke.sh(contract of one image) andscripts/interop.sh(every host against every edge, every fixture, any broker), with expectations computed from the fixture, andtests/known-bugs.tsvfor verified upstream defects. - Schemas for capability documents, call results and events;
make documentsvalidates every document the self-tests produce. - CI natively on amd64 and arm64, the cross-stack self-test on every broker, and a tag-driven release to GHCR.
- Upstream candidates workflow, weekly and on demand: the latest release of every adapter library and broker against its pin, with a self-test of each newer one and a decision table (
make upstream,make candidate-<name>).
Upstream notes
The self-test passes on all four brokers with 0 failures. Verified upstream defects are listed in tests/known-bugs.tsv and described in docs/COMPATIBILITY.md.
Not in this release
- Templates, DataSets, arrays and properties in fixtures.
- A choice of MQTT version (every adapter speaks MQTT 3.1.1 except srad, which speaks MQTT 5 only), TLS and broker authentication.
