 ### Fixes
 
+- Fixed an issue with tag values in metrics not being properly serialized ([#3065](https://github.com/getsentry/sentry-dotnet/pull/3065))
 - Moved the binding to MAUI events for breadcrumb creation from `WillFinishLaunching` to `FinishedLaunching`. This delays the initial instantiation of `app`. ([#3057](https://github.com/getsentry/sentry-dotnet/pull/3057))
 - The SDK no longer adds the `WinUIUnhandledExceptionIntegration` on non Windows platforms ([#3055](https://github.com/getsentry/sentry-dotnet/pull/3055))
 - The scope transaction is now correctly set for Otel transactions ([#3072](https://github.com/getsentry/sentry-dotnet/pull/3072))
