HoneyHive Python SDK v1.6.0

What's Changed

Ingestion API keys
- HoneyHive(...), HoneyHiveTracer.init(...), and evaluate(...) accept ingestion_api_key=, also read from HH_INGESTION_API_KEY. The ingestion key is sent only on the routes that create sessions and write events, including OTLP trace export; every other route keeps using api_key. When it is unset, api_key is used for ingestion too, so existing setups are unchanged. A value that is set but is not an hh_ingst_ key raises ValueError at construction rather than failing later at request time.

Connection settings resolve the same way in every entry point
- The client, the tracer, evaluate(), and the CLI now resolve api_key, ingestion_api_key, and the API URL through one resolver, so a single process can no longer authenticate with one key in evaluate() and another in a tracer. An explicit argument beats the environment, and a blank value counts as unset.
- HH_API_KEY and HH_API_URL are the preferred variables and win when more than one is set. HONEYHIVE_API_KEY, HONEYHIVE_SERVER_URL, and HH_SERVER_URL still work but are deprecated and emit a DeprecationWarning once per process. If you set both HONEYHIVE_API_KEY and HH_API_KEY to different values, evaluate() and the CLI now use HH_API_KEY; they previously preferred HONEYHIVE_API_KEY.

Tracer: RecursionError from trace.get_tracer() after tracer shutdown
- Shutting down the main HoneyHiveTracer reset the global OpenTelemetry provider to a fresh ProxyTracerProvider, which delegates back to the global provider — itself. Any subsequent opentelemetry.trace.get_tracer(...) call (including module-level calls made when importing libraries such as mcp) raised RecursionError. Shutdown now clears the global provider so OpenTelemetry returns its own proxy.
Events API: retry config now controls events.export()
- HoneyHive(retry_config=...) and HH_MAX_RETRIES were accepted and ignored. They did not reach events.export() / export_async(), which fell back to a fixed budget of 3 retries. Both configuration methods now set the retry budget for events.export() / export_async().

Anthropic extras cap anthropic below 1.0.0
- honeyhive[openinference-anthropic], honeyhive[traceloop-anthropic], and the bundles that include them now require anthropic<1.0.0, and the OpenInference extras also require openinference-instrumentation-anthropic<2.0.0. A mismatched pair either raised ModuleNotFoundError on import or logged a dependency conflict and skipped instrumentation. The SDK already implicitly depended on anthropic<1.0.0 as that was the only version available, which worked until Anthropic recently published v1.0 of their SDK.
LangChain extras now install langchain-openai
- honeyhive[openinference-langchain] and honeyhive[traceloop-langchain] pull in langchain-openai>=1.0.0 alongside langchain. These dependencies were always required for tracing to work correctly with LangChain but they weren't declared before.
