transfer is no longer accepted

What changed

Usually ignored rather than rejected, so the call succeeds and does something subtly different.

Affects transfer on InventoryChange reachable from 5 operations. Grep for it: nothing else will tell you.

Who is affected

Code that sends Square's InventoryChange objects, used by 5 Square operations.

Before and after

Code that breaks

await client.post("/…", {
  // transfer is now ignored, not rejected
  transfer: value,
});

Based on Square’s published API specification. How severity is decided.
