clean up

no, ~1.0.3 respects more semantic versioning than ~1.0. If you read the getcomposer.org docu you will realize that 1.0.3 will move up the last digit only, with 1.0 you will move not only bugfixes but enhancements and features added as well. If some of the additions happen to break some custom extensions for a project that makes a lot of money is not very good.
