According to Google, the release makes GenAI v2, identified as otel_semconv_1_44, the default telemetry schema and removes call_llm. The release notes list ADK_TELEMETRY_SCHEMA_VERSION_OPT_IN=otel_semconv_1_36 as the setting for retaining the legacy schema. Sources: Google
Google reported promoting 12 features to stable and claimed up to 8× faster string-model agent turns. That performance claim concerns string-model agent turns; it does not establish an equivalent speedup for complete applications or model inference. Sources: Google
What to do
- Before deploying google-adk==2.13.0, check dashboards, trace queries and alerts against staging traces using otel_semconv_1_44.
- If telemetry migration needs more time, set ADK_TELEMETRY_SCHEMA_VERSION_OPT_IN=otel_semconv_1_36 to retain the legacy schema. Sources: Google
