[PEPr] Comment on RFC::Drop requirement of renaming a package when migrating from PHP 4.x to PHP 5.x

The original intention was to be able to maintain (and e.g. send fixes etc.) for two separate trains/major versions. Another special case was redesigning the API for a cleaner PHP5-interface, which would still need a new major version as long as the package is not in alpha-stage anymore (because of BC-break). As long as a dev is sure about the implications of his decision I agree with Sebastian that the proposal is a viable solution now that PHP4 is dead since so long. And if package.xml deflects the minimum php-version needed, that should prevent to break peoples existing installations. -- http://pear.php.net/pepr/pepr-proposal-show.php?id=606
