  - Time out for app start info retrieval has been reduced to 10s
  - If `autoAppStarts` is `false` and `setAppStartEnd` has not been called, the app start event processor will now return early instead of waiting for `getAppStartInfo` to finish
 
+### Improvements
+
+- Set dart runtime version with parsed `Platform.version` ([#2156](https:/getsentry/sentry-dart/pull/2156))
