Changelog

[1.5.0] - 2026-11-02

Fixed

• The package root and ./testing exports have a source condition, like ./render, so workspace tests that resolve with source (Durable's and pi-env's, as the Environments workflow runs them) work without a build.

[1.4.0] - 2026-10-21

Breaking Changes

• Adapters trust typed instrumentation inputs; behavior for malformed values is unspecified. Carrier extraction checks required string identities, without validating their format.
• Adapters must implement TelemetrySpan.addLink(). Normalized span snapshots include carrier-shaped context and parent identities and ordered links.
• Adapters with optional metric or propagation capabilities must carry them through TelemetryContext.metrics and TelemetryContext.propagation on roots, spans, and extracted parents.

Added

• Opaque string-map carriers and optional TelemetryPropagation injection/extraction, with passive root fallback for absent or invalid carriers and shared NOOP_TELEMETRY_PROPAGATION.
• Initial SpanOptions.links and late span.addLink() with context targets and optional attributes, including settled target spans and extracted remote parents.
• Optional TelemetryMetrics counters, up-down counters, and histograms with boundary hints and exemplar contexts, plus shared NOOP_TELEMETRY_METRICS instruments.
• Optional context capability members, populated by the no-op and in-memory adapters and checked by adapter conformance.
• NOOP_TELEMETRY_CONTEXT is typed as TelemetrySpan, matching the shared inert span it provides.
• Metric schema definitions and createTypedMetrics() with exact instrument names, kinds, and required/optional low-cardinality attributes.
• In-memory propagation across processes, link and measurement snapshots, and adapter conformance cases for propagation, links, and optional metrics.
• StoredSpan, StoredTrace, and TelemetryStore define backend-independent trace discovery, trace retrieval, and metric queries. @earendil-works/pi-telemetry/render exports renderTrace() for plain-text span trees with attributes, durations, errors, events, and cross-trace links; merged spans are deduplicated by ID and links are never followed.
