+  ### Dashboard deep linking
+
+You can now link directly to any shipment or container in the Terminal49 dashboard using a container number, bill of lading, booking number, or reference number — no internal IDs needed.
+
+Use the URL pattern:
+
+```
+https://app.terminal49.com/shipments/find?q={identifier}
+```
+
+The link automatically resolves to the correct tracking page, making it easy to link from a TMS, ERP, spreadsheet, or automated notification.

+
+  ### Calculated Last Free Day
+
+The Smart LFD system now includes a **calculated Last Free Day** derived from carrier demurrage tariff rules. When a shipping line or terminal hasn't reported an LFD, Terminal49 computes one using the applicable tariff — including free days, start events, holidays, and business-day rules.
+
+Calculated values appear as a fallback in the `import_deadlines` field on the container API. If a reported LFD is available from the carrier or terminal, it takes priority.

+
+  ### Smart LFD dashboard columns
+
+The container dashboard now includes two new columns for accounts with Smart LFD enabled:
+
+- **Calc. Line LFD** — the calculated Last Free Day derived from carrier tariff rules
+- **Smart LFD** — the best available LFD with its source displayed, so you can see at a glance whether the date comes from the shipping line, terminal, or a tariff calculation
+
+Click the Smart LFD value to open a detail modal showing the full calculation breakdown, including tariff inputs, free days, and the day-by-day calendar.

+
+  ### Bug fixes
+
+- **Hapag-Lloyd booking tracking** — Fixed an issue where certain Hapag-Lloyd bookings could return an invalid number error, preventing container data from loading
