 # Changelog
 
+## [2.9.2](https://github.com/google/adk-python/compare/v2.9.1...v2.9.2) (2026-09-18)
+
+
+### Highlights
+
+This release focuses on refining telemetry behavior by correcting how OpenTelemetry event names are handled across different environments.
+
+* **Telemetry**: OpenTelemetry event names are now preserved on platforms outside of Agent Engine, ensuring more accurate and consistent tracking. ([9110770](https://github.com/google/adk-python/commit/9110770dc487283b95844ad843db9eec9e56e92d))
