+### Fixed
+- Queued shipping jobs did nothing: `PollShipmentTrackingJob` and
+  `SyncCarrierVouchersJob` ran every time but finished in milliseconds
+  without contacting any carrier. The queue worker clears facade instances
+  before each job, and the Shipping manager was bound with `bind()`, so the
+  facade then built a fresh manager with no drivers registered. It's now a
+  singleton. Tracking from the scheduler never worked on a deployed app
+  because of this (a "Sync now" click worked, since it doesn't go through
+  the queue).
+- ELTA extra parcels are no longer tracked by their own number: ELTA only
+  tracks a multi-parcel send by its main voucher and rejects the extra
+  parcels' numbers ("Λάθος ΣΥΔΕΤΑ"), which logged an error for each of them
+  on every tracking run.
