 === Changed
 * We are officially announcing the end of life for the Nashorn JavaScript engine used by FusionAuth Lambda functions. All new functions have defaulted to the GraalJS since version `1.35.0`. The engine is not being removed in the release, but this is an official notice that we plan to remove this engine in early 2024. Please review your lambda functions and ensure the `engineType` is set to `GraalJS`.
