# Release History

## Unreleased
## 1.2.0 (2026-05-18)

### Features Added
- Forward `instrumentation_options` kwargs to instrumentors
([#149](https://github.com/microsoft/opentelemetry-distro-python/pull/149))
- Add A365-specific OpenAI Agents SDK instrumentor (`A365OpenAIAgentsInstrumentor`). When `enable_a365=True`, the distro uses this bundled instrumentor instead of the upstream `opentelemetry-instrumentation-openai-agents-v2`, producing spans with the A365 versioned envelope format, `custom.parent.span.id`, per-message indexed attributes, detailed token counts, and `graph_node_parent_id` for handoffs.
([#132](https://github.com/microsoft/opentelemetry-distro-python/pull/132))

### Bugs Fixed
- Fix duplicate chat spans and HTTP spans not propagating in LangChain
([#147](https://github.com/microsoft/opentelemetry-distro-python/pull/147))
- Revert: Fix `get_caller_pairs` userId fallback
([#141](https://github.com/microsoft/opentelemetry-distro-python/pull/141))
- Capitalize env var to avoid case-sensitive conflicts
([#137](https://github.com/microsoft/opentelemetry-distro-python/pull/137))
- Add product context fallback for subchannels
([#129](https://github.com/microsoft/opentelemetry-distro-python/pull/129))

### Other Changes
- Port Agent365 integration tests using real distro pipeline
([#146](https://github.com/microsoft/opentelemetry-distro-python/pull/146))
- Make `microsoft-agents-hosting-core` and `microsoft-agents-activity` optional dependencies
([#117](https://github.com/microsoft/opentelemetry-distro-python/pull/117))
- Pin genai util
([#145](https://github.com/microsoft/opentelemetry-distro-python/pull/145))
- Update telemetry SDK name to `microsoft-opentelemetry`
([#138](https://github.com/microsoft/opentelemetry-distro-python/pull/138))
- Update azure monitor exporter minimum version
([#136](https://github.com/microsoft/opentelemetry-distro-python/pull/136))
