#945482 by Scott Falconer: Fixing PDOException on empty values in multi-value fields. #970548: Fixing undefined index warning. Fixing JavaScript bypass for compatibility with Drupal 7 updates. Other code improvements.

Fixed compatibility with Drupal 7.0-alpha1. Added documentation through hook_help(). Validation should be skipped when deleting a node. Fixed translatability of all strings.

#250496 by rssaddict: Removed all database-specific code. #234821 by sigsby: Check for content.module before CCK-dependent code.

Added single node scope. Improved error messages. Verified support for node and user reference fields. Better handling for empty values.

Initial commit of unique_field module. This module provides an option to require that node titles or CCK field values are unique.
