v2.16.1

Summary

We packed this release with a bunch of new features and performance improvements:

• Support for multiple CORS origins in the event handler
• New parser support for SQS events wrapped in Kinesis Firehose
• Huge performance improvements when using the CodePipelineJobEvent event source
• Tons of documentation enhancements on Feature Flags and Batch Processing

⭐ Huge thanks to new contributors: @roger-zhangg and @darnley!!

Support for multiple CORS origins in the event handler

Docs: Multiple CORS origins

We added support for multiple origins in CORS when defining an event handler. Supporting multiple CORS origins enables API calls from different domains and the integration of various sources. Your existing code will continue to work as it is.

New parser support for SQS events wrapped in Kinesis Firehose

Docs: Kinesis Firehose SQS events

SQS event notifications can sometimes be ingested into Lambda via an intermediary such as Kinesis Firehose (i.e. Lambda event source), for various architectural reasons - batching, retries, etc. However, from the Lambda function's perspective, the intermediary might not be too important; what's important is the SQS event notification itself. Now you can easily parse and access the inner payload for Kinesis Firehose-wrapped SQS events.

Huge performance improvements when using the CodePipelineJobEvent event source

Thanks to @darnley, we found out that using the CodePipelineJobEvent came with a performance penalty, and we fixed it by optimizing the way we load dependencies.

Documentation enhancements on Feature Flags and Batch Processing

We've completely revamped and fine-tuned all the samples and snippets for our Feature Flags and Batch Processing utilities! We took the time to bring the examples closer to real-world usage and fixed any syntax errors. We can't wait for you to try them out!
