+**Features**
+
+- The Sentry SDK now has experimental support for performance monitoring.
+  The performance monitoring API allows manually creating transactions and instrumenting spans, and offers APIs for distributed tracing.
+  The API is currently disabled by default and needs to be enabled via a compile-time `SENTRY_PERFORMANCE_MONITORING` flag.
+  For more information, take a look at the more detailed [documentation of performance monitoring](https://docs.sentry.io/platforms/native/performance/).
+- Sentry now has an explicit `sentry_flush` method that blocks the calling thread for the given time, waiting for the transport queue to be flushed. Custom transports need to implement a new `flush_hook` for this to work.
+
+**Fixes**
+
+- Fix Sentry API deadlocking when the SDK was not initialized (or `sentry_init` failed).
+- The rate limit handling of the default transports was updated to match the expected behavior.
+- The Windows OS version is now read from the Registry and is more accurate.
+- The `SENTRY_LIBRARY_TYPE` CMake option is now correctly honored.
+- The Linux Modulefinder was once again improved to increase its memory safety and reliability.
