We have been there, no chance to go back again with such tags. Also the new release process RFC (https://wiki.php.net/rfc/releaseprocess) solves the BC issues between minor updates (5.4 to 5.5, or 5.3 to 5.4 f.e.). It is our and our users role to explain that to their ISPs, admins, etc. Cheers, -- Pierre @pierrejoye -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
