A new version of my Drupal module for item reservation has been released. This is an upgrade which does no longer use a node's field but a custom database table to track the reservation status. The main reason is: when someone reserves an item in version 7.x-1.x, the node gets updated and is highlighted in the list of nodes. The user may easily come along this view and all surprise is gone. Another new feature is the usage of Ajax to update the data and display the result. Please read the UPGRADE text for more information on how to upgrade your installation.
