Order-send reliability fixes: • Re-sending an order after a failed or slow send no longer duplicates the items on the table. • The Send button no longer unlocks early after a myDATA error, so a second send can't start for the same order.

• More reliable table closing: if the app is interrupted while issuing a receipt or closing a table, the sale now completes automatically the next time the app opens — no more stuck tables or missing receipts • New: self-supply document (Δελτίο αυτοπαράδοσης) for complimentary items, printed with full VAT analysis (enabled per store in Settings) • Stability improvements

What's new • More reliable card payments and receipts • Accurate totals for products sold by weight (per-kilo) • Smoother table transfers — no lost items or payments • Automatic receipt recovery when the myDATA/AADE link briefly drops • Card-terminal support for additional currencies • Stability and performance improvements

Fix: in rare cases where a product was added with a rapid double-tap, the table total could show less than the sum of its items. The total is now always derived directly from the order's items, so the cashier screen, receipt, and balance always agree.

In this version we added a server hook that enumerates the items of an order correctly for legacy versions. Furthermore in table order transfer and partial transfer we fetch the live table before transferring. This way we eliminate any conflicts if a waiter places additional items in the order during the transfer.

What's new: • More reliable card payments — fixed cases where items stayed "unpaid" even though the charge had gone through. • If the app closes mid-checkout, the sale now completes automatically on relaunch — no lost sales. • More stable auto-archive table closing. • New progress indicator while the receipt is being issued. • Fixed a false "No internet connection" message during checkout.

Advanced payment security is introduced. In this version we guarded Viva payments through the card terminal connected to the waiter app against Viva webhooks firing multiple times. The OCC lock and the CAS mode still remain as guards for concurrent payments of the same item. Only one payment gets through.

In this version we streamlined all concurrent operations like simultaneous payment of an item from different waiters or concurrent transfers of a a table order from different waiters etc. We used advanced techniques like OCC (Optimistic Concurrency Control) and CAS (Compare-And-Swap).

In this version we upgraded the lock during transfer of an order from table to table so that no concurrent operation on that table can be made during the transfer.

In this version we streamlined the discount order flow in the payment screen.

We correctly developed the concurrent payment lock. Now if two waiters or managers in the restaurant try to simultaneously pay the same item an Alert will show and only the first one who tried gets through the payment.

In this version we updated the discount methods so that no sub-decimal residual values remain while rounding the numbers. Another improvement is that now two users cannot cancel an item simultaneously.

In this version we introduce the "Universal printing" feature, which allows for products to be printed in printers outside the table section when ordering.

In this version we introduce two new features: 1. Blocked printer. If a product Order will be printed in two printers then you can print it only in the printer of the section where the table is located. This requires a setting in Product View in the Dashboard. 2. We added support for products that are made of other products.

In this version we added stock control for a product per size, which can be overridden by a dashboard setting which allows only central stock control for a certain product.

In this version we streamlined the work flow regarding the card terminal payments. We also improved the function of secondary prices to work faster with fewer re-renders.

In this version we added the functionality for a restaurant owner to track the actual food cost, after he configures the material structure of each dish.

In this version we removed the Viva web hooks Failed Event as it was unnecessary. Then we upgraded the functions executed from pressing a button to be blocked when the button is pressed, regardless of the UI blockage.

In this version we added a spinner and disabled state in the Card payment button in the table auto release section.

In this version we offer to our customers connectivity to POS Card terminals of all Greek banks plus to Viva, MyPOS, MyPay. Furthermore we redesigned the payment modal for Viva payments to use webhooks and have only one button.

In this version we added further checks while paying and we also enabled Viva hooks for seamless payments.

In this version we streamlined the ordering procedure and added a limit for the resending of temporary receipts.

This version has improved UI in the Ordering and payment item cards.

In this version we changed the UI in Order screen and Payment screen. Buttons now have better shadow/elevation for depth. There is better typography hierarchy.

In this version animations were added in splash screen, login page, order page, orders of day and month pages, daily dishes page.
