Kong release schema

I noticed a new kong image was published this morning (June 15th) and allthough it has the same tag the version of the alpine base image was bumbed to 3.16.0. I was actually waiting for this (because 3.15 had some vulnerabilities) and was wondering if there exists some sort of release schedule stating which versions (also from the base images like alpine, unbuntu, etc) are published and will be published and when (in near future :slight_smile: )?
