That default value is now changed to +'html5', which obviously stands for the modern HTML 5 standard. + +Nothing should be really broken by this change, but if your application +relies on the default value, you should double-check it and either +explicitly set the desired format, or adapt your front-end to use proper +HTML 5 formatting.
