+ Removed the "post content" permission and replaced it by more fine-grained permissions such as "maintain static pages", "maintain personal blog", "maintain stories", etc.
o Usability improvements to teasers:
+ Teaser forms are no more. Teasers are extracted automatically but can also be instructed using a delimiter "---". Furthermore, when a post it too short for a teaser, the user won't be bother with teaser stuff anymore.
+ Added an option to set the teaser length, or to disable teasers all together.
+ When previewing a post, both the short (if any) and the full version of a post are shown. This addresses a common complaint; for example, when writing a book page there was no way you could preview the short version of your post.
+ Forum posts can be teasered now. This is particularly helpful in the context of drupal.org where we promote forum topics.
