Users can now select the underlying kernel version for their build hosts, enabling use of the updated Amazon Linux 2023 featuring Linux kernel 6 and newer packages, which may improve compatibility and performance.

This choice facilitates gradual adoption by running experimental builds on Amazon Linux 2023 while maintaining stability on Amazon Linux 2 for production projects. The feature is available in most AWS Regions except GovCloud and China, where Linux 2023 is standard.
