[FEEDBACK REQUEST] Python 3.15 preview #216

Today, we have published the preview AWS Lambda Python 3.15 runtime. You can use it to build and deploy Python 3.15 Lambda functions in both deployment formats:

• Managed runtime (ZIP): select the python3.15 runtime when deploying your function code as a .zip archive.
• Container image (OCI): build and deploy your function using the preview base image public.ecr.aws/lambda/python:3.15-preview.

⚠️ Public preview - not for production use. Preview runtimes are provided for feedback and testing only, and should not be used for production workloads. They are not covered by AWS Technical Support and are not eligible for the Lambda SLA. The purpose of preview runtimes is to gather feedback prior to General Availability, while breaking changes are still possible. These runtimes and images may be modified or discontinued without notice.

Please share any feedback below! Thank you!
