Call to undefined function: epublish_save_topic() in epublish.module on line 1211

I had a chance to bang on the 4.7 (CVS) versoin of the module today. Looks great, except for one bug I dug up. It first appeared immediately after enabling the module and accessing /admin/settings/epublish:

Fatal error: Call to undefined function: epublish_save_topic() in /var/www/drupal/modules/epublish/epublish.module on line 1211

When I refreshed, the error didn't occur again. However, I am able to successfully reproduce the error by trying to add a section at /admin/epublish/add/section.

The module is attempting to save the section using epublish_save_topic($misc_topic); on line 1211. However, the function has apparently been renamed to epublish_form_topic_submit and now requires that $form_id be passed along with the $edit array: epublish_form_topic_submit($form_id, $misc_topic).
