Summary

We are thrilled to announce support for querying Powertools Lambda layers ARN using SSM public parameters.

We also added support for API Gateway WebSocket events in the parser utility and added Lambda layer support in the AWS Malaysia region (ap-southeast-5).

Thanks to @tcysin, we have added deprecated flag support when working with OpenAPI operations in the Event handler.

🌟 ⭐ Congratulations to our new contributors @TurnrDev and @tcysin for getting their first PR merged!

Using Powertools SSM public parameters

Docs

Customers can now retrieve the latest Powertools for AWS Lambda (Python) layer ARN for Python versions 3.8 through 3.13 on both x86_64 and arm64 architectures using AWS Systems Manager Parameter Store.

To do this, simply use the AWS CLI command aws ssm get-parameter with the appropriate parameter name. For example, use /aws/service/powertools/python/<architecture>/<python_version>/latest , replacing with either "x86_64" or "arm64", and <python_version> with your desired Python version (e.g., "python3.8", "python3.9", etc.).

New parser models

Docs

We have improved the Parser utility by adding support for events from API Gateway WebSocket.

Here are all the modules we have added for EventModel:

  • APIGatewayWebSocketMessageEventModel - For WebSocket messages events
  • APIGatewayWebSocketConnectEventModel - For WebSocket $connect events
  • APIGatewayWebSocketDisconnectEventModel - For WebSocket $disconnect events

🚀 Thanks @ran-isenberg for another great contribution!

Using deprecated flag in the OpenAPI schema

Docs

You can now use the deprecated flag in your OpenAPI schema to mark operations that are no longer recommended. This helps customers clarify which parts of your API should be avoided in favor of newer options.

Last but not least, thanks to @junkor-1011 for catching a bug in the Parser utility.

Summary

In this release we added support for the newly released Python 3.13 AWS Lambda managed runtime 🚀.

We’ve also revamped the Parser documentation, and added MutualTLS scheme support when working with OpenAPI schemas and Event handler.

Oh hey, please welcome Ana as our new full-time maintainer - @anafalcao 🎉

🌟 ⭐ Congrats to our new contributor @Sector95 for getting their first PR merged.

Python 3.13 support

You can now use Powertools for AWS Lambda (Python) with the new Python 3.13 runtime in AWS Lambda.

We’ve partnered with the AWS Lambda team for this launch and have been testing our toolkit for the past few weeks to ensure compatibility with no changes from your side.

To start using Powertools for AWS with the new runtime, you can upgrade to this version via PyPi or use the latest version (v4) of our Lambda layers.

Parser documentation

Docs

In this release, we have improved the Parser documentation to include comprehensive examples of using this feature.

Summary

We are thrilled to announce that Powertools for AWS Lambda (Python) now offers AWS Lambda layers in the AWS GovCloud (US) regions.

🌟 ⭐ Thanks to @SimonBFrank's amazing work, our Logger utility is now thread-safe when handling extra keys.

New AWS GovCloud (US) Lambda Layer ARNs

You can now use Powertools for AWS Lambda (Python) Lambda layers in the AWS GovCloud (US) regions, enhancing customer experience by making our pre-packaged Lambda layers available in this AWS partition.

To take advantage of the new layers, you need to update your functions or deployment setup to include one of the new Lambda layer ARN from the table below:

AWS GovCloud (us-gov-east-1)

Architecture Layer ARN
x86_64 arn:aws-us-gov:lambda:us-gov-east-1:165087284144:layer:AWSLambdaPowertoolsPythonV3-{python_version}-x86_64:{version}
ARM arn:aws-us-gov:lambda:us-gov-east-1:165087284144:layer:AWSLambdaPowertoolsPythonV3-{python_version}-arm64:{version}

AWS GovCloud (us-gov-west-1)

Architecture Layer ARN
x86_64 arn:aws-us-gov:lambda:us-gov-west-1:165093116878:layer:AWSLambdaPowertoolsPythonV3-{python_version}-x86_64:{version}
ARM arn:aws-us-gov:lambda:us-gov-west-1:165093116878:layer:AWSLambdaPowertoolsPythonV3-{python_version}-arm64:{version}

New thread-safe methods when working with extra keys in the Logger utility

Docs

Before this release, customers might have encountered issues when using append_keys between thread executions.

You can now use new thread-safe methods for managing extra keys in the Logger utility, ensuring safe and efficient logging in concurrent environments.

Acknowledgements

Last but not least, we are thrilled to see our customers adopting v3, as it indicates we are moving in the right direction.

Summary

We are excited to announce the first release following the v3 GA release. In this release we addressed a bug in the Parser utility as well as a regression in the naming of our public Lambda layers.

Thanks to @mw-root we added support for Event Source for CodeDeploy Lifecycle Hook.

🌟 ⭐ A big thank you to our new contributors: @emmanuel-ferdman, @garysassano and @mw-root.

Correct Naming for Powertools Lambda Layer x86_64

In our initial v3 release, we mistakenly named the x86_64 Lambda layer as x86. We've corrected this issue in the current release, ensuring our Lambda layers now use the correct architecture naming convention.

For those who have already adopted the v3 Layer for this architecture, we recommend updating the ARN to use the new name using the table below as reference. The version of the Layer using the incorrect name will continue to be available but new releases, including this one, will follow the correct and updated naming convention.

Architecture Python version Layer ARN
x86_64 3.8 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python38-x86_64:{version}
x86_64 3.9 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python39-x86_64:{version}
x86_64 3.10 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python310-x86_64:{version}
x86_64 3.11 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python311-x86_64:{version}
x86_64 3.12 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python312-x86_64:{version}

New CodeDeploy Lifecycle Hook Event Source Data Class

Docs

You can now use CodeDeployLifecycleHookEvent for a better experience with type hinting and code completion support when working with AWS Lambda functions that process AWS CodeDeploy events.

dataclass_code

Parser utility is now returning ValidationError

Before this release when parsing an event failed, we were catching the ValidationError raised by Pydantic and re-raising it as an InvalidModelTypeError.

We now raise the ValidationError directly, allowing our customers to handle data validation errors more effectively.

Thanks for this important bug report @jhare-rectangle

Acknowledgements

Last but not least, we are thrilled to see our customers adopting v3, as it indicates we are moving in the right direction.

v3.0.0

Summary

We are super happy to announce our new major version – v3.0.0 🎉🎉!

We have made Pydantic v2 the default for Powertools for AWS Lambda (Python) utilities, this was the most requested feature from you. Pydantic v2 is the most impactful upgrade, offering better performance and greater flexibility compared to Pydantic v1.

The second most requested feature was publishing Powertools Lambda layers for different Python versions and architectures, allowing for easier integration across various Lambda environments. This is crucial for libraries like Pydantic v2 and AWS Encryption SDK, which are used by Powertools and require installation for specific architectures and Python version.

🌟 We couldn’t have done this without you 🌟

Thanks to everyone in the community for their patience and assistance as we've been working on this release. A special thanks to @ericbn for their amazing contributions to this milestone.

We care deeply about minimizing breaking changes

Over the past few months, we carefully selected each breaking change to make, and crafted an extensive upgrade guide to ease your transition to v3. Please let us know whether we can make your upgrade process easier.

Note

The section below is an excerpt of what's available in the Upgrade guide

What’s New in v3

  • Drop support for Pydantic v1
  • New AWS Lambda Layer ARNs
  • New default values for Event Source Data Classes
  • Headers are now case-insensitive in Event Handler
  • Backwards incompatible changes

Drop support for Pydantic v1

We no longer support Pydantic v1 and have updated our toolkit to support only v2 of the library. We made this change after Pydantic v1 reached End-of-Life on June 2024.

Use the Pydantic v2 Migration Guide to migrate your custom Pydantic models to v2.

New AWS Lambda Layer ARNs

To give you a better experience, we're now building our public Powertools for AWS Lambda (Python)'s Lambda layers for specific Python versions (3.8-3.12) and architectures (x86_64 & arm64).

With this change we can now include architecture-specific versions of both Pydantic v2 and AWS Encryption SDK and give you a more streamlined setup.

To take advantage of the new layers, you need to update your functions or deployment setup to include one of the new Lambda layer ARN from the table below:

Architecture Python Version Layer ARN
x86_64 3.8 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python38-x86:{version}
x86_64 3.9 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python39-x86:{version}
x86_64 3.10 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python310-x86:{version}
x86_64 3.11 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python311-x86:{version}
x86_64 3.12 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python312-x86:{version}
arm64 3.8 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python38-arm64:{version}
arm64 3.9 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python39-arm64:{version}
arm64 3.10 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python310-arm64:{version}
arm64 3.11 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python311-arm64:{version}
arm64 3.12 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-python312-arm64:{version}

Event Source Data Classes default values

We have modified the Event Source Data classes so optional dictionaries and lists now return empty dictionaries or lists instead of None. This improvement simplifies your code by eliminating the need for conditional checks when accessing these fields, while maintaining backward compatibility with previous implementations.

data_class

Event Handler: headers are case-insensitive

According to the HTTP RFC, HTTP headers must be case-insensitive. As a result, we have deprecated the get_header_value function to align with this standard. Instead, we recommend using app.current_event.headers.get to access header values directly.

Consequently, the case_sensitive parameter in this function no longer has any effect, as we now ensure consistent casing by normalizing headers for you. This function will be removed in a future release, and we encourage you to adopt the new method to access header values.

Summary

This release adds support for OpenAPI extensions to help you describe functionality beyond the OpenAPI Spec.

We also made tons of improvements in the Idempotency docs based on customers feedback on navigation, examples, and limitations.

🌟 ⭐ Huge thanks to everyone who helped in this release, specially @bertpl for crushing a bug in the Idempotency feature.

Working with OpenAPI extensions

Docs

You can now define extensions using the openapi_extensions parameter. This unblocks a common use case in defining Amazon API Gateway extensions like Authorizers, Integrations, etc.

openapi_extension

Idempotency revamped docs

Based on customer feedback at the Serverless Days ANZ, we improved all code snippets, made navigation more granular, and split DynamoDB vs Redis persistence storage (Infra vs Runtime).

We also made it more explicit everywhere that Idempotency is bound to a particular time window (1h by default) that you can adjust.

Summary

This release enhances the Batch Processing feature, which you can now customize to not throw an error when the entire batch of items fails to process.

We have also added three new Pydantic models to our Parser feature to work with authorizers in Amazon API Gateway.

Thanks to @adriantomas, customers can bring their own boto3 client when using Feature Flags feature.

🌟 ⭐ A big thank you to everyone who helped make this release.

Working with full batch failures

Docs

You can now set the raise_on_entire_batch_failure option to False to prevent the Batch Processing utility from throwing a BatchProcessingError, when all records in a batch fail to process. This is useful when working with functions that handle batches with a small number of records, or when you use errors as a flow control mechanism.

batch_process

New Parser models

Docs

You can now use the new Pydantic models to validate payloads originating from authorization events in REST and HTTP APIs.

parser

Here are all the modules we've added:

  • ApiGatewayAuthorizerToken - For REST API Authorizer events using Token
  • ApiGatewayAuthorizerRequest - For REST API Authorizer events using Request
  • ApiGatewayAuthorizerRequestV2 - For HTTP API Authorizer events using Request

Customizing boto3 client configuration for Feature Flags

Docs

You can now bring your own boto3 client instance when using Feature Flags. This is ideal when you want to reuse or customize the appconfigdata client.

appconfig

Last but not least, thanks to @Wurstnase for helping us to fix a bug when using CORS in the Event Handler feature.

Summary

We're excited to announce Batch resolvers in GraphQL Event Handler to tackle the infamous N+1 problem in GraphQL 💪, making it easier to work with batching in AWS AppSync.

Thanks to @danieljnchen, the validation utility now supports referencing internal schemas within your JSON files. 🌟

🌟 ⭐ A big thank you to our new contributors: @scampbell5, @matteofigus, and @danieljnchen.

Batch resolvers in Event Handler GraphQL

Docs

You can now use a batch resolver to handle batch requests coming from AWS AppSync. This is useful when AWS AppSync has batching enabled for Lambda Resolvers as it allows the aggregation of as many requests as possible before invoking your AWS Lambda function, effectively solving the N+1 problem in GraphQL.

batch_resolver

Validation feature now supports custom handlers

Docs

You can now control JSON schema references with custom handlers. This is useful when you might want to optimize caching, reducing HTTP calls, or fetching them from non-HTTP endpoints.

validation

Last but not least, @scampbell5 helps us fix the types for partition and offset in the KafkaEventRecord Event Source Data Class.
