 - Spans and Transactions now implement `IDisposable` so that they can be used with `using` statements/declarations that will automatically finish the span with a status of OK when it passes out of scope, if it has not already been finished, to be consistent with `Activity` classes when using OpenTelemetry ([#4627](https://github.com/getsentry/sentry-dotnet/pull/4627))
 - SpanTracer and TransactionTracer are still public but these are now `sealed` (see also [#4627](https://github.com/getsentry/sentry-dotnet/pull/4627))
 - CaptureFeedback now returns a `SentryId` and a `CaptureFeedbackResult` out parameter that indicate whether feedback was captured successfully and what the reason for failure was otherwise ([#4613](https://github.com/getsentry/sentry-dotnet/pull/4613))
+- `IScopeObserver.AddBreadcrumb` now takes a `SentryHint` as a second parameter ([#4694](https://github.com/getsentry/sentry-dotnet/pull/4694))
