 ### Version 0.4.0 (Working Draft, June 18, 2026)
 
+- **Removed** (documentation correction, August 2026): References to a `copilot-otel.jsonl` local mirror/companion artifact. PR #32280 removed the file-export pipeline that produced it (`COPILOT_OTEL_FILE_EXPORTER_PATH` injection, artifact inclusion, and forwarding script); Copilot CLI spans are now expected to be exported directly to the configured OTLP backend and queried there.

 - **Changed**: Reframed 0.4.0 as a non-breaking compatibility revision rather than a replacement telemetry standard.
 - **Preserved**: `observability.otlp`, direct OTLP export, `OTEL_EXPORTER_OTLP_ENDPOINT`, `OTEL_EXPORTER_OTLP_HEADERS`, `GITHUB_AW_OTEL_TRACE_ID`, `GITHUB_AW_OTEL_PARENT_SPAN_ID`, `TRACEPARENT` compatibility, built-in setup/conclusion spans, `gen_ai.system`, `gen_ai.usage.total_tokens`, and raw OTLP JSONL mirror behavior.
 - **Clarified**: Standard OpenTelemetry attributes such as `gen_ai.provider.name` and CI/CD attributes may be emitted as additive aliases, not replacements for existing fields.
