 - feat(asyncio): Add on-demand way to enable AsyncioIntegration by @sentrivana in [#5288](https://github.com/getsentry/sentry-python/pull/5288)
+
+  You can now enable the `AsyncioIntegration` on demand, after calling `sentry_sdk.init()`. This is useful in scenarios where you don't have
+  the event loop running early on, or when you need to instrument multiple event loops.
+
+```python
+import sentry_sdk
+from sentry_sdk.integrations.asyncio import enable_asyncio_integration
+
+# Initializing the SDK as early as possible, when there is no event loop yet
+sentry_sdk.init(
+    ...
+    # No AsyncioIntegration in explicitly provided `integrations`
+)
+
+async def main():
+    enable_asyncio_integration()  # instruments the current event loop
+    # ...your code...
+```
