What's New in Mostly Charged
1.2.1
October 13, 2026
Fixed: a pack saved without a nickname stopped every backup. The add form now checks every field, and the update names any such pack after its code, as an import now does for a nameless spreadsheet row or older backup. Rename a pack, or correct its brand, capacity or retirement threshold, from the menu on its page. A refused backup now names the pack to fix. Delete a pack you no longer want. Retiring still keeps a worn-out pack's history. Backups made by 1.0.0 that would not restore now do.
