There is no change yet. The labels and resx files cannot be stored in the database. This is a limitation. It also affects cloud based deployment. This is why if using Azure, for instance, you must prepare locally and include in the deployment package all themes, labels, and other resources that are kept in App_Data folder. Once the project is deployed, they must remain read-only. For example, to include an imported language pack in the deployment, include the ~/App_Data/Sitefinity/GlobalResources folder in project.
