Product version to 0.9.0, frontend in lock-step, Unreleased notes moved into a dated section per ADR-007. The plugin contract stays at 0.16.0: it moved after v0.8.1 and is already recorded in this release's notes, and nothing since touched the contract surface. A minor rather than a patch: collector behaviour changed in ways an integrator must know about. A reported machine number no longer becomes the PC's asset number, it builds a controls link instead; a second PC claiming a machine is treated as a claim rather than a handover; and a backup revision chain is now per source PC rather than per asset.
Architecture Decision Records
Each ADR captures a single architectural decision: the context, the decision itself, the consequences, and the alternatives considered. ADRs are immutable once accepted. Superseded ADRs stay in this folder with a pointer to the newer ADR.
Status definitions
- PROPOSED: drafted, awaiting decision
- ACCEPTED: decision is in effect
- SUPERSEDED: replaced by a later ADR (link forward)
- DEPRECATED: no longer in effect, no replacement
