I don't think it makes a huge difference. As long as 1.4 is not to be released soon it would be better to port it to 1.3. This way people can use it. But honestly I think you develop it against zinc and xml parser. Zinc has been updated in 1.3 lately but I don't know if it is the newest stuff. Sven knows it.�Hi Norbert!Yes, I know that the situation is better with Zinc (I checked the code and really look nice and simple to understand). I only mentioned XMLRPC as a mere example of how the things become unusable so fast.Talking about this what you guys consider best, migrate XMLRPC to 1.3 or directly to 1.4 ?Norbert
