What's Changed

There were a lot of time since [**0.5.7 OpenTelemetry** release](https://github.com/airtai/faststream/releases/tag/0.5.7) and now we completed **Observability** features we planned! **FastStream** supports **Prometheus** metrics in a native way!

Special thanks to roma-frolov and draincoder (again) for it!

To collect **Prometheus** metrics for your **FastStream** application you just need to install special distribution

cmd
pip install faststream[prometheus]


And use **PrometheusMiddleware**. Also, it could be helpful to use our [**ASGI**](https://faststream.airt.ai/latest/getting-started/asgi/) to serve metrics endpoint in the same app.

python
from prometheus_client import CollectorRegistry, make_asgi_app
from faststream.asgi import AsgiFastStream
from faststream.nats import NatsBroker
from faststream.nats.prometheus import NatsPrometheusMiddleware

registry = CollectorRegistry()

broker = NatsBroker(
middlewares=(
NatsPrometheusMiddleware(registry=registry),
)
)

app = AsgiFastStream(
broker,
asgi_routes=[
("/metrics", make_asgi_app(registry)),
]
)


Moreover, we have a ready-to-use [**Grafana** dashboard](https://grafana.com/grafana/dashboards/22130-faststream-metrics/) you can just import and use!

To find more information about **Prometheus** support, just visit [our documentation](https://faststream.airt.ai/latest/getting-started/prometheus/).

What's Changed

This it the official **Python 3.13** support! Now, **FastStream** works (and tested) at **Python 3.8 - 3.13** versions!

Warning: **Python3.8** is EOF since **3.13** release and we plan to drop it support in **FastStream 0.6.0** version.

Also, current release has little bugfixes related to **CLI** and **AsyncAPI** schema.
