 - `ISpan` and `ITransaction` have been renamed to `ISpanTracer` and `ITransactionTracer`. You will need to update any references to these interfaces in your code to use the new interface names ([#2731](https://github.com/getsentry/sentry-dotnet/pull/2731))
+- Removed obsolete setter from `Sentry.PlatformAbstractions.Runtime.Identifier` ([2764](https://github.com/getsentry/sentry-dotnet/pull/2764))
 - The TracePropagationTarget class has been removed. Use the SubstringOrRegexPattern class instead. ([#2763](https://github.com/getsentry/sentry-dotnet/pull/2763))
