Reproducible Kotlin Compiler Artifacts

For the Kotlin team, security is always a priority. One of the measures we are taking to protect Kotlin builds from an attack is to make them reproducible. With reproducible builds, you can easily check that any artifacts or dependencies that you want to use haven’t been tampered with.

Artifacts that are officially published on GitHub and Maven Central can now be verified against ones obtained on other machines. This greatly reduces the possibility of attacks targeting build agents.

As of Kotlin 1.8.0, Kotlin/Native supports 27 targets. However, we can’t support all of them equally well. To prioritize quality over quantity, we’ve decided to split the targets into tiers and deprecate some of them.

We’ve created a dedicated document to be a single source of information for all Kotlin/Native targets which we’ve split into 3 tiers, depending on how well each is supported and has been tested.
