In addition to adaptations for compatibility with newer versions of Transformations 6.x-1.0-beta1 and Field Tool 6.x-1.0-beta1 (both of which are now required in these versions, so make sure those modules are also updated), the Drupal operations themselves also feature a couple of improvements.
Initial release. Does the most important stuff already - creating/loading/saving nodes, and adding/extracting node fields. As of this writing, Field Tool supports text and number CCK fields (plus the obvious body and title stuff, of course) which should already cover a significant percentage of use cases.
