 ## 2.48.0
 
+Middleware spans are now disabled by default in Django, Starlette and FastAPI integrations. Set the `middleware_spans` integration-level
+option to enable capturing individual spans per middleware layer. To record Django middleware spans, for example, configure as follows
+
+```python
+  import sentry_sdk
+  from sentry_sdk.integrations.django import DjangoIntegration
+
+  sentry_sdk.init(
+      dsn="<your-dsn>",
+      integrations=[
+        DjangoIntegration(middleware_spans=True),
+      ],
+  )
+```
