Python 3.15, tested against the real thing
Python 3.15, tested against the real thing

Mangum 0.22.0 moves the supported Python window forward and backs every release with end-to-end tests against a real Lambda runtime.

pip install mangum==0.22.0

Python 3.15 is supported. The full suite and strict type checking pass on 3.15 (#404).

Python 3.9 is no longer supported. The minimum is now Python 3.10 (#393).

Adapters are now verified against a real Lambda runtime. The test suite deploys Mangum to LocalStack and drives it through a Lambda Function URL and an API Gateway REST API with real HTTP requests - covering the HTTP v2 and REST v1 event formats plus lifespan startup, instead of relying only on hand-written mock events (#400, #401).
