* Convert XConfigure into constructors Previously, we discussed the possibility of converting the config types into internal ones. But due to the cyclic dependencies it introduces, we are only converting XConfigure into constructors and document that XConfig types are most likely are not going to be directly used by developers. In package documents, constructors will be nicely listed under the config types and they won't be yet another standalone symbol developers need to learn about. Fixes #1130. * Add the changes to the CHANGELOG
