+- Experimental: Allow using OTel for performance instrumentation (#2272) by @sentrivana
+
+    This release includes experimental support for replacing Sentry's default
+    performance monitoring solution with one powered by OpenTelemetry without having
+    to do any manual setup.
+
+    Try it out by installing `pip install sentry_sdk[opentelemetry-experimental]` and
+    then initializing the SDK with:
+
+    ```python
+    sentry_sdk.init(
+        # ...your usual options...
+        _experiments={"otel_powered_performance": True},
+    )
+    ```
+
+    This enables OpenTelemetry performance monitoring support for some of the most
+    popular frameworks and libraries (Flask, Django, FastAPI, request...).
+
+    We're looking forward to your feedback! Please let us know about your experience
+    in this discussion: https://github.com/getsentry/sentry/discussions/55023
+
+    **Important note:** Please note that this feature is experimental and in a
+    proof-of-concept stage and is not meant for production use. It may be changed or
+    removed at any point.
