I just uploaded a new version of the fishing assetpack which is in line with all of the most recent changes to the icon-assetpacks. The newest zip archive adds spritesheets for shadows, outlines and selections as .png files to the set and I also reworked the naming conventions, that they fit together with the most recent changes of all other iconpacks.
This update does not add any new assets, but improves the usability of the set slightly.
