0.53.0 Migration Guide

The most likely issue you'll run into is from kube when using Resource trait which has been split:

+use kube::api::ResouceExt;
-    let name = Resource::name(&foo);
-    let ns = Resource::namespace(&foo).expect("foo is namespaced");
+    let name = ResourceExt::name(&foo);
+    let ns = ResourceExt::namespace(&foo).expect("foo is namespaced");
