I was doing hardcore Drupal 4/5/6 for about 4 years, but have been out of the loop for a while. Perhaps somebody can answer these for me: 1) Have any significant improvements been made to simplify and streamline the Drupal Forms API? 2) Is there now any easy and reliable way to define models/CCK-types in code rather than web interface? 3) Is there now a programmatic schema and data migrations solution that does not have to be used from a web interface? 4) Do modules still have to be named *.module ? 5) Has any namespacing been put into place? 6) Have any new measures been put into place to discourage developers from putting SQL queries in template code? 7) Do modules and "node" objects have better OOP integration? Thanks
