A new version of CataBlog has been released, 0.7.0. This update includes a complete code rewrite, form enhancements and catalog items can now be tagged. Use the new tagging feature to filter your catalog to show only the items you want for that page. For instance, if you have a catalog of hardware products, some might be sinks and others doors, if you tag each item appropriately you can use the shortcode attribute tag to show only items with that tag.
Users of the old CataBlog plugin should be careful before upgrading, uploaded images are now stored in the uploads folder under another folder named catablog. Before they were being stored in a folder in your wp-content folder, if you upgrade from 0.6.5 to 0.7.0 you most likely will loose all your images. You can fix this by manually moving all the thumbnail images from wp-directory/wp-content/catablog to wp-directory/wp-content/uploads/catablog/thumbnails. The next revision will handle the image migration gracefully so only worry about this if you are upgrading specifically from 0.6.5 to 0.7.0 version.
