LGTM, just one small suggestion.

🚢 from profiling

From a Serverless perspective, we are locked into supporting node 16 until at least June 2024. This is similar to what happened with node 14 support, where we were locked to using the v3 releases. Are we just dropping support because node 16 is no longer LTS?

Is this

Yes, ideally this release was supposed to happen a few months ago when Node 16 was officially no longer LTS

Approving to not block the v5 release, everything looks good on the Serverless side, but we'd be pinned to the v4 line until August 2024 – date where AWS will drop support for Node 16 AWS Lambdas.
