The plan was/is to break BC hard when it is going to be broken. What about including the BC-breaking changes within #ifdef BREAK_COMPAT or something similiar (#if PHP_VERSION > 500?) Otherwise one risks to forget what changes to make, and also you can already start making those changes. AND you can add a compile-time option 'do-not-break-compatibility' Greetz, Jeroen -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
