Describe the feature

AWS Synthetics runtime support for Python 3.9 and above

Use Case

AWS has recently announced the end of life (EOL) for Python 3.8 in AWS Lambda runtimes. Unfortunately, the synthetic canary runtimes have not been updated to support newer Python versions. As a result, the Lambdas generated by synthetic canaries are running on an outdated Python runtime that will soon be obsolete.

AWS Notification on Python 3,8 Runtime the EOL

Starting on October 14, 2024, Lambda will no longer apply security patches and other updates to the Python 3.8 runtime used by Lambda functions, and functions using Python 3.8 will no longer be eligible for technical support. Also, Python 3.8 will no longer be available in the AWS Console, although you can still create and update functions that use Python 3.8 via AWS CloudFormation, the AWS CLI, AWS SAM, or other tools. Starting February 28, 2025, you will no longer be able to create new Lambda functions using the Python 3.8 runtime. Starting March 31, 2025, you will no longer be able to update existing functions using the Python 3.8 runtime.
