Composition code families are shown in your own language, across all ten supported languages, and the list has grown to eleven: Ceramic, Glass, Leather, Metal, Other, Paper, Plastic, Rubber, Stone, Textile and Wood.
The Family dropdown, filter and column under Settings → Configuration → Composition codes follow your language, and the list sorts alphabetically in it. The composition code picker groups options under the translated family name.
Existing codes are linked to a family automatically. A family you set by hand is kept, the ISO fibre codes go to Textile, and packaging codes go to their material family. Codes you added by hand without a family stay without one, and show an empty Family cell until you assign one.
Families are maintained by us, so you assign one to a code rather than creating or renaming them. Packaging weight reporting rolls codes up by family, now including fibre codes.
