v2.9.0

Summary

🎙️ Powertools for AWS Lambda (Java) 1.x.x is now end-of-life. See announcement in #1895. We strongly recommend you to upgrade to 2.x.x following our upgrade guide.

This release fixes a bug where metrics dimensions were incorrectly persisted across Lambda invocations. Additionally, cold start detection now respects the Lambda environment (e.g. Lambda Managed Instances does not incur cold starts).

🌟 Thanks to @Attyuttam for contributing for the first time!
