The bundled copy changed:\n\n- Its modules are now locked so they cannot be changed while running\n\n- Several text-format checks no longer add pattern or content-encoding details to the JSON Schema they generate (JSON Schema is a standard way to describe what data something accepts)\n\n- Slovak and Belarusian translations gained a label for IBAN bank account numbers\n\n**Why**\n\nThis is mostly a library update. Schemas generated from these checks may describe text fields in less detail than before.\n\n- Area: Dependencies\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 0\/5\n- Scope: individual\n- Heads-up: no"}
