v1.25.10

Summary

This patch release addresses the following main issues:

• Event Handler: Previously, Lambda handlers decorated with event source data class that also use Event Handler were incompatible
• Event Handler: Raising a ServiceError like NotFound as part of an exception handler ended up propagating a ServiceError instead of converting into a non-successful response (e.g., 4xx)
• Event Source Data Classes: Missing date field type annotation in SESEvent to string instead of list, and missing fields like cc, bcc, sender, and reply_to, and dkim related fields
• Parameters: Previously, customers couldn't easily clear parameters (SSM, Secrets Manager, AppConfig, DynamoDB) cache as part of their automated tests

v1.25.7

Summary

This patch release addresses bugs on Logger, Event Handler REST API, Idempotency, and a static type annotation on middleware factory utility.

We also updated our issues to use the new GitHub Issue Form, including a new Ask a Question, and Static typing mismatch report. The latter addresses an increase of bug reports that are better categorized as static typing mismatch - this will help us understand whether we might be able to support both Mypy and Pyright in the future.

Logger

Thanks to @eliasbrange, customers using clear_state=True will no longer be affected by custom keys being accidentally removed in subsequent invocations - a regression introduced two releases ago. We improved tests on clear_state functionality.

Idempotency

Thanks to @ojongerius, customers changing the incoming event within the Lambda handler will no longer impact idempotency hash calculation. This was caused by Python's default pass by reference behaviour.

Event Handler REST API

Thanks to @sthuber90, customers receiving API calls that contain whitespace in path parameters - /customer/power tools - will no longer return 404s. Despite API Gateway correctly decoding whitespace, our regex for safe and unsafe URI chars missed an explicit whitespace.

Middleware Factory

Thanks to @huonw, Mypy customers using --strict mode will no longer complain about the return type of custom decorators using lambda_handler_decorator. It's a hard problem to solve considering our support for Python 3.6+. Later in the year, we'll look into the value-effort ratio of supporting strict mode, and how to gradually bring typing_extensions package across the board.

Huge thanks to new contributors: @sthuber90, @eliasbrange, and @ojongerius

v1.25.6

Summary

This patch release fixes a regression in Logger introduced in 1.25.3 when using clear_state=True. A fix for customer formatters introduced in 1.25.3 ended up introducing a regression, where standard keys like level, location and timestamp no longer being present when using clear_state=True for the default Logger formatter.

Thanks to @alexanderluiscampino for a high quality bug report, and @HAK-CODE for confirming the issue two hours ago, we managed to reproduce it quickly, improved our tests, and thus making this emergency release.

1.25.3

Summary

This patch release is strictly about customers bringing their own Logging Formatter.

This release ensures that when using Clear State with a custom formatter, all previously added keys will be cleared. It also guarantees that Lambda Context information will no longer be cleared abruptly before logs are printed (also for custom formatters).

There is no code change needed on customers end. We also improved the documentation to clarify the most common use cases on bringing your own formatter, and exceptional cases where you want to replace the entire Powertools Logger Formatter logic.

Huge thanks to @jacobdarrossi for spotting, and @ilias-at-adarma for confirming this bug.

v1.25.2

Summary

This patch release addresses two main bugs: 1/ API Gateway Lambda Authorizer data class regex to validate for proxy resources (proxy+), and 2/ metrics to be automatically flushed when a single metric has 100 values.

Next release will focus on two newly identified bugs on Logger (custom formatter, child logger). Subsequently, our bandwidth remains focused on addressing the subpar experiences and operational excellence.
