The new version of the free Tag Groups WordPress plugin comes with an improved shortcode and some bug fixes and improvements. The shortcode tag_groups_info can now display the label (name) of a tag group. The output is not formatted.
[tag_groups_info group_id=1 info=label]
Furthermore, there are some performance improvements.
We also fixed a bug that prevented users of the premium plugin from assigning tags to groups if the permission setting should actually only restrict the editing of groups.
