We had several exports where the configuration passed to constructs or functions was using a class with a different suffix then Config. If you are using a language like C#, Java, Python, or Go you might have needed to specify these classes in your CDKTF application. To simplify the usage we changed every suffix to be Config, so if you currently use one of the others please rename them to use the Config suffix. No options were changed in the process, only the names were aligned.

This would be one example of the change to be made (this is in Java):

import software.constructs.Construct;
import com.hashicorp.cdktf.App;
import com.hashicorp.cdktf.TerraformStack;
import com.hashicorp.cdktf.CloudBackend;
-import com.hashicorp.cdktf.CloudBackendProps;
+import com.hashicorp.cdktf.CloudBackendConfig;
import com.hashicorp.cdktf.NamedCloudWorkspace;

    public static class Demo extends TerraformStack{

        public Demo(Construct scope, String id){
            super(scope, id);
-            new CloudBackend(this, CloudBackendProps.builder()
+            new CloudBackend(this, CloudBackendConfig.builder()
                    .organization("hashicorp")
                    .workspaces(new NamedCloudWorkspace("demo"))
                    .build()
            );
