Current snapshot
| Component | Current observed state | Meaning |
|---|---|---|
| UHP specification | 2026-08-11 · Draft standard | Normative protocol version remains unchanged. |
| HarnessRouter Community Edition | v0.5.5 · 18 Aug 2026 | Latest tagged reference-implementation build observed in the official repository. |
| Published conformance evidence | Full-class report for CE 0.3.0 | Conformance evidence is version-specific; a newer product tag does not automatically mean a newer published conformance report. |
Do not merge the version numbers. UHP uses a date-based protocol version. HarnessRouter Community Edition uses software tags. A change to HarnessRouter can add UI, providers or media features without changing the UHP wire contract.

Protocol release vs implementation release
A protocol release changes the standard that independent clients and servers implement. An implementation release changes one product that implements the protocol. UI refinements, starter kits, model-provider integrations and media workflows can move quickly without requiring a UHP specification revision.
What this tracker will record
- New UHP protocol versions and normative changelog entries.
- HarnessRouter Community Edition tags that materially affect developers or the reference implementation.
- Conformance-suite revisions and new published conformance reports.
- Independent UHP servers, clients or SDKs with reproducible evidence.
- Native vendor adoption announcements that name UHP directly.
