- Bugfix: when updating a book page, the name of the author did not change. - Bugfix: the "Edit comments" part of the node administration pages did not display the correct comments. - Bugfix: somethimes, update in a book page would mess up the book. - Improvement: when "node administrators" update a book page through the "update this book page"-link (like regular users do), their update will be subject to moderation. - Improvement: made some intermediate changes to the filter mechanism. Needs more work.
