Changeset 53685 for trunk/src/wp-includes/post.php

Message:

Media:

• Deprecate wp_get_attachment_thumb_file().
• Make wp_get_attachment_thumb_url() an alias of wp_get_attachment_image_url(). This fixes it to return the proper thumbnail URL and fall back to returning the URL to image_meta['thumb'] if only that exists.
