Release notes

Sourced from aws-lambda-powertools's releases.

v3.22.1

Summary

In this release, we fixed a regression introduced by [PR #7227](aws-powertools/powertools-lambda-python#7227) that affected customers using the Event Handler utility with nested metadata annotations such as annotated_types or Interval. Thanks to @​rtandy for identifying the bug and validating the fix.

We also fixed small bugs in type annotations and in our documentation.

⭐ Congrats @​rpivo and @​czechnology for contributing to this project for the first time!

Given our commitment to all of our customers using Powertools for AWS Lambda (Python), we will keep Pypi{target="_blank"} v2 releases and documentation 2.x versions to prevent any disruption.

Migrate to v3 from v2

!!! info "We strongly encourage you to migrate to v3. However, if you still need to upgrade from v1 to v2, you can find the upgrade guide."

We've made minimal breaking changes to make your transition to v3 as smooth as possible.

First Steps

Before you start, we suggest making a copy of your current working project or create a new branch with git.

  1. Upgrade Python to at least v3.9.
  2. Ensure you have the latest version via Lambda Layer or PyPi{target="_blank"}.
  3. Review the following sections to confirm if you need to make changes to your code.

Drop support for Pydantic v1
