I've received a possibly final update for our icon set (version 5, 2013-05-29).
- a new icon the "Categories" app and a single "category" (both use the same icon)
- a new icon for single "tag" and for multiple "tags"
- a new icon for a possible "delete search" function in search fields
- six new icons for linking and unlinking, made for the rich text editor
Please generate a new icon set and install them.
