- Made the node forms support "help texts": it is not possible to configure Drupal to display submission guidelines, or any other kind of explanation such as "NO TEST POSTS", for example. - Added node versioning: it is possible to create revisions, to view old revisions and to roll-back to older revisions. You'll need to apply a SQL update. I'm going to work on the book module now, so I might be changing a few things to enable collaborative, moderated revisions - but feel free to send some first feedback, if you like. - Added some configuration options which can be used to set the minimum number of words a blog/story should consist of. Hopefully this will be usefull to stop the (almost empty) test blogs. - Various improvements: + Fine-tuned new node permission system. + Fine-tuned the functions in node.inc. + Fine-tuned some forms. + XHTML-ified some code.
