This is the initial release of jRails and covers all of the functionality in the built in Rails prototype_helper as well as some of the functionality in scriptaculous_helper. This release includes support for basic AJAX calls (form_to_remote, link_to_remote), RJS, observers (observe_form, observe_field) as well as a limited set of functionality for draggables, droppables, sortables and visual effects. Support will continue to grow as the jQuery UI and FX libraries mature.
