+### Fixed
+- Checkout crashed ("Driver [acs] not supported", a 500) when a shipping
+  method pointed at a driver that is no longer registered — e.g. a carrier
+  commented out while its shipping method still exists in the admin. Such
+  methods are now left out of the options offered at checkout
+  (`Modules\Core\Shipping\Support\RegisteredDriverRateResolver`); the admin
+  is unchanged.
+- The Box Now locker map at checkout only appeared when the shipping
+  method's **code** was exactly `box-now`; a method with any other code
+  (e.g. `boxnow`) never showed it, and switching options cleared the chosen
+  locker. Box Now is now recognized by its driver being a `BoxNowRateDriver`
+  (`Modules\Core\Shipping\Support\BoxNowShipping`), not by any name. The
+  admin order page's Create Shipment (locker + boxes form) and the
+  shipment's locker line use the same check.
