there are 2 new features:

1) able to set a parent post when saving a post form
2) set the taxonomies using a comma seperated list in a textbox

for both new features you obviously need the form to save a new post type. Do this in the usual way:
add a post title field to the form, goto it's advanced tab, check save to post type and select the post type from the list.

1) to set a parent post, add a dropdown field to the form, goto the advanced tab and check the populate with a post type checkbox, select the post type and then also check the "try save to parent" chekbox. When you save the form, you can now specify a panent post. Obviously the post you select for the dropdown must be the same post type you select for the post title field above

2) to save a comma seperated list of taxonomies, add a single line text field to your form. Then got the advanced tab and check the "save to taxonomy" checkbox. then selecy your taxonomy from the lsit. The taxonomy MUST NOT BE heirarchical (eg. it must be like post tags). When filling out the form, users can enter their own list or taxonomies. If the taxonomy exists it will simply link the taxonomy to the post type. If it is new, it will create the taxonomy and link it.
