Rechercherichtung

Start by reviewing Python 3.15 changes, the existing runtime update issues #7430, #5411 and #3272, and the compatibility CI matrix. Then check dependency support and run the test, Nox, type-check and lint workflows on Python 3.15. Done means the runtime is validated across supported architectures, CI and documentation are updated, and the layers and SAR applications are published and verified; this spans multiple systems and depends on upstream runtime support.

Beschreibung

internal triage
Why is this needed?

Python 3.15 has been officially released. The AWS Lambda runtime is in preview, so we can start identifying compatibility issues and prepare Powertools before it becomes generally available.

This follows the runtime updates tracked in #7430, #5411 and #3272.

Which area does this relate to?

Tests, Static typing, Automation, Other

Solution

Compatibility preparation

  • Review Python 3.15 changes and check compatibility of required and optional dependencies, including native wheels for x86_64 and arm64. Track upstream blockers.
  • Run the full test suite, Nox dependency isolation sessions, type checks and linters on Python 3.15. Fix compatibility issues while preserving support for existing runtimes.
  • Add Python 3.15 to the compatibility CI matrix and update dependencies and lockfiles where needed.

Lambda validation and release

  • Track support in CDK, SAM and Lambda build images. Update the layer construct, build configuration, SAR templates and deployment workflows as support becomes available.
  • Validate on Lambda using the preview where possible, then complete E2E validation against the generally available runtime on x86_64 and arm64.
  • Update package classifiers, supported-runtime documentation and relevant examples.
  • Publish and verify the Python 3.15 layers and SAR applications in the supported regions and partitions where the runtime is available, then announce support.
