Those date ranges in the Box Builder trip up almost everyone — they look like an order-editing window, but they're actually the fulfillment week the box's contents apply to. They're now labeled Fulfillment Dates, with plain-English tooltips on every box explaining exactly what they mean (and, for customizable plans, when customization opens).

Publishing got safer too. Publishing a box is permanent — it adds the items to every pending order in that fulfillment week and opens those orders for customer edits. The new confirmation spells out exactly how many orders will receive the items and for which dates, and asks you to check an "I am ready to publish this box configuration" box before the publish button unlocks. No more clicking through a one-line warning and asking support to unwind it.
