v3.13.0

Summary

In this release, we renamed the Redis class to Cache in our Idempotency utility and added support for the valkey-glide library.

Thanks to our new contributors @​AlisonVilela, @​Artur-T-Malas, and @​kiitosu, we also fixed bugs in our Event Source Data Class utility. ⭐🏅

Working with the new CachePersistenceLayer class

Docs

You can now use our CachePersistenceLayer classes, which are more generically named, in place of the previous Redis-specific classes when using the Idempotency feature.

For backward compatibility, we've maintained the old Redis class names. However, these are now marked as deprecated and will be removed in the next major version.

We've also added support for valkey-glide, providing more flexibility for your caching implementation needs.

If you are using the RedisPersistenceLayer class in your codebase, you can use the new CachePersistenceLayer as a drop-in replacement.

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.

Quick summary

Pydantic	We have removed support for Pydantic v1	No
Parser	We have replaced DynamoDBStreamModel AttributeValue with native Python types	Yes
Parser	We no longer export Pydantic objects from parser.pydantic.	Yes
Lambda layer	Lambda layers are now compiled according to the specific Python version and architecture	No
Event Handler	We have deprecated the get_header_value function.	Yes

Types file	We have removed the type imports from the shared/types.py file	Yes

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

!!! note "No code changes required"

As of June 30, 2024, Pydantic v1 has reached its end-of-life, and we have discontinued support for this version. We now exclusively support Pydantic v2.
