+* Deprecate publishing to the [Terraform Module Registry](https://registry.terraform.io/search/modules?q=poseidon)
+  * Typhoon docs have always shown using Git-based module sources, not the Terraform Module Registry
+  * Module usage should be `source = "git::https://github.com/poseidon/typhoon/...` not `source = poseidon/kubernetes/...`
+  * Terraform's Module Registry requires subtree mirroring typhoon to special terraform-platform-kubernetes repos, only supports release versions (no commit SHAs or forks), only ever contained Flatcar Linux modules (not Fedora CoreOS) for historical reasons
+  * Note, this does not affect Terraform Providers like `poseidon/matchbox` or `poseidon/ct`, the registry works well for providers
