Version 1.39.1/0.60b1

This is a patch release on the previous 1.39.0/0.60b0 release, fixing the issue(s) below.

Fixed

• opentelemetry-util-http, opentelemetry-instrumentation-requests, opentelemetry-instrumentation-wsgi, opentelemetry-instrumentation-asgi: normalize byte-valued user-agent headers before detecting synthetic sources so attributes are recorded reliably. (#4001)

opentelemetry-instrumentation-google-genai 0.5b0

• 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).
• 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).
