The latest release of the Webform module for Drupal 8 includes a schedule email handler, support for core's quick edit module and experimental system tray, and better tools to manage external libraries.
Added new autocomplete/tagging style widget for thread members.
Note: If you are upgrading from beta1 or beta2, you need to go to Admin -> Structure -> Private Messages -> Private Message Threads -> Manage Form Display [requires field_uid module], and for the 'members' field, select the 'private message members autocomplete' widget, and then save.
