The included copy was updated. It can now check IBAN (international bank account number) strings, and its messages in many languages include a name for that format. Some of the code that builds its error messages and size checks was also reworked.\n\n**Why**\n\nThis is an internal update with little visible effect.\n\n- Area: Dependencies\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 0\/5\n- Scope: individual\n- Heads-up: no"}
