GD Star Rating 1.9.3 is second maintenance release targeting WordPress 3.0 reported problems. Many bugs are fixed with this release, and many things changed to add support for custom post types. This release includes fixes for all bugs reported that I could confirm so far.
Articles panel is expanded with different filter for custom post types. Some of integration functions are improved. Readme file is updated with more FAQ entries. Database Tools panel got one more tool you need to be very, very careful about because it will remove all stored rating data from database.
TinyMCE button and plugin are fixed to support taxonomies changes in WP 3.0 and custom post types. Same goes for Builder panel, and for the widgets that had problems with grouping by taxonomies. Few more problems with the meta boxes integration on post edit page are also fixed.
If you find anymore bugs, please report them via comments or in the forums.
