## 1.0

<Update label="1.0.1" description="June 17, 2026" tags={["Fiddler Google ADK SDK"]}>
  * **Initial PyPI Release**
    * First version of `fiddler-adk` published to PyPI (`pip install fiddler-adk`).
    * `GoogleADKInstrumentor`: sets up an isolated Fiddler tracing pipeline via `FiddlerClient` and promotes it to the global tracer provider so ADK's `gcp.vertex.agent` tracer resolves to it.
    * `ADKSpanProcessor`: backfills `gen_ai.conversation.id` from child spans onto the parent `invocation` root span, fixing orphan-root rendering in the Fiddler UI.
    * Span-type classification, content extraction, and attribute normalization are delegated to the Fiddler backend's `GoogleADKSpanMapper`.
    * Supported versions: `google-adk >= 1.34.2` (1.x and 2.x lines), `opentelemetry-api >= 1.37.0`, Python 3.10-3.14.
