- Fix overwritten log attributes in vertexai instrumentation ([#3925](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3925)) - Add the `GEN_AI_OUTPUT_TYPE`, `GEN_AI_REQUEST_CHOICE_COUNT` and `GEN_AI_REQUEST_SEED` sem conv request attributes to events/spans generated in the stable instrumentation. This was added pre sem conv 1.36 so it should be in the stable instrumentation. See ([#4011](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/4011)).

- Ensure log event is written and completion hook is called even when model call results in exception. Put new log event (` gen_ai.client.inference.operation.details`) behind the flag `OTEL_SEMCONV_STABILITY_OPT_IN=gen_ai_latest_experimental`. Ensure same sem conv attributes are on the log and span. Fix an issue where the instrumentation would crash when a pydantic.BaseModel class was passed as the response schema ([#3905](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3905)). - Add the `GEN_AI_OUTPUT_TYPE` sem conv request attributes to events/spans generated in the stable instrumentation. This was added pre sem conv 1.36 so it should be in the stable instrumentation. Fix a bug in how system instructions were recorded in the `gen_ai.system.message` log event. It will now always be recorded as `{"content" : "text of system instructions"}`. See ([#4011](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/4011)).

- Fix service tier attribute names: use `GEN_AI_OPENAI_REQUEST_SERVICE_TIER` for request attributes and `GEN_AI_OPENAI_RESPONSE_SERVICE_TIER` for response attributes. ([#3920](https://github.com/open-telemetry/opentelemetry-python-contrib/issues/3920)) - Added support for OpenAI embeddings instrumentation ([#3461](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3461)) - Record prompt and completion events regardless of span sampling decision. ([#3226](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3226)) - Filter out attributes with the value of NotGiven instances ([#3760](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3760)) - Migrate off the deprecated events API to use the logs API ([#3625](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3628))

- Add jsonlines support to fsspec uploader ([https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3791](#3791)) - Rename "fsspec_upload" entry point and classes to more generic "upload" ([https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3798](#3798)) - Record content-type and use canonical paths in fsspec genai uploader ([https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3795](#3795)) - Make inputs / outputs / system instructions optional params to `on_completion`, ([https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3802](#3802)). - Use a SHA256 hash of the system instructions as it's upload filename, and check if the file exists before re-uploading it, ([https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3814](#3814)).

- Initial barebones package skeleton: minimal instrumentor stub, version module, and packaging metadata/entry point. ([#3805](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3805)) - Implement OpenAI Agents span processing aligned with GenAI semantic conventions. ([#3817](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3817)) - Input and output according to GenAI spec. ([#3824](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3824))
