WCPOS – Point of Sale (POS) plugin for WooCommerce

更新日志

1.9.0 – 2026/05/15

Almost three months of work — here are the highlights:

• New receipt template gallery — pick from ready-made receipt, invoice, quote, packing slip, gift receipt, kitchen ticket, and right-to-left templates, and switch between them in settings.
• Multiple receipt templates — install and enable several templates side by side instead of being stuck with one.
• Thermal printer support — print receipts directly to thermal printers (58mm and 80mm) over network, Bluetooth, or USB, with a guided setup wizard in the WCPOS apps.
• Customer Tax IDs — a new Tax ID field on the customer form, ready for VAT, ABN, GST, and other regional tax numbers.
• Pro: Coupons at the POS — search for and apply coupons at checkout, with coupon pills in the cart and support for sequential discounts.
• Pro: Refunds at the POS — refund POS orders directly from the till, with a full audit trail.
• Pro: Per-store receipt templates — assign different templates to different stores, and drag-and-drop to reorder them.
• Plus lots of smaller fixes — tax and coupon calculations, third-party plugin compatibility, faster syncs, and better translations.

1.8.14 – 2026/02/19

• Hardened DB migration locking — upgrade now uses the WordPress core upgrader lock (WP_Upgrading) with an atomic acquisition check and a shutdown fallback, preventing concurrent migrations on high-traffic sites (#540)
• Fixed offline gateway ignoring POS checkout status — orders placed with the Cash or Card gateway while offline now respect the configured POS checkout status instead of defaulting to “processing” (#544)
• Fixed i18n locale fallback and caching — translation lookups no longer retry locales that returned a definitive 404, reducing unnecessary network requests on every page load (#543)
• Fixed settings page clipping on some WordPress themes — the left side of the settings panel was being cut off on sites where #wpcontent has extra padding (#545)
• Reduced extensions catalog cache TTL — the extension directory now refreshes every hour instead of daily, so newly published extensions appear faster (#546)
• Allowed php-jwt advisory on PHP 7.4 — resolved a PHP Scoper install failure caused by a security advisory that only affects newer PHP versions (#541)

1.8.13 – 2026/02/17

• Fixed root cause of duplicate product metadata — POS order processing no longer clones product objects in the stock/coupon path, preventing repeated meta rows from being re-saved on each stock update (#537)
• Added a safer duplicate-meta repair migration — a new one-time cleanup removes only exact duplicate (post_id, meta_key, meta_value) rows for POS-touched products/variations, reducing API payload size and memory pressure without deleting distinct meta values (#537)
• Expanded regression coverage for discount and stock edge cases — added tests for coupon recalculation behavior, variation pricing paths, and stock-reduction lifecycle to prevent regressions (#537)
• Reduced diagnostic log noise — high-volume top-meta-key context is now opt-in so normal logs stay readable while deep diagnostics remain available when needed (#537)

1.8.12 – 2026/02/13

• One-time cleanup of duplicate metadata — a migration automatically removes thousands of junk meta rows that accumulated on POS-touched products and orders, resolving memory exhaustion and slow API responses on affected stores (#532)
• Reduced redundant order saves in payment gateways — Card and Cash gateways no longer call $order->save() before payment_complete() / update_status(), which already save internally (#532)

1.8.11 – 2026/02/13

• Fixed critical memory exhaustion on large stores — API responses were re-reading all metadata from the database on every request, causing extreme memory usage on stores with large catalogs (#519)
• Fixed O(n²) loop in order tax calculation — variable shadowing caused quadratic iteration over line item meta (#519)
• New meta data monitoring — REST API responses now detect resources with excessive metadata and fall back to a safe response mode, preventing out-of-memory crashes (#521)
• Security hardening — masked auth tokens in test endpoint, added directory protection for temp receipt templates (#519)
• Updated all JS and PHP dependencies to latest stable versions (#521, #526)
• Pro: Redesigned Edit Store page with modern React/Tailwind UI
• Pro: Fixed SQL injection vulnerability in analytics and store authorization bypass

1.8.9 – 2026/02/11

• Completely rebuilt settings page — new modern architecture with Vite, TanStack Router, headless UI components, zustand state management, and responsive layout with grouped sidebar navigation (#495, #498, #505)
• New Extensions directory — browse, discover, and manage extensions directly from POS settings, with Pro integration hooks, GitHub links, and new-extension badges (#497, #500, #510)
• New Logs page — view, filter, and paginate log entries from file and database sources with expandable details and unread counts (#504, #511)
• Redesigned email settings — granular per-email toggles replace the old on/off switch, with new cashier notification options (#502, #508)
• Fixed POS prices persisting to product database — price modifications made at the POS no longer overwrite the stored product price (#509)
• Fixed coupon calculations ignoring tax — coupon subtotal filters are now tax-aware, preventing incorrect discount amounts (#507)
• Fixed security plugin conflicts — CSP headers are now stripped on POS pages so Content-Security-Policy rules from security plugins no longer break the interface (#503)
• Fixed WordPress 6.7+ compatibility — deferred translation calls in the Activator to avoid the “too early” notice (#498)

1.8.8 – 2026/02/06

• Completely rebuilt translation system — switched to i18next with proper plural handling and regional locale fallback, loaded on-demand from jsDelivr and decoupled from plugin version updates (#37, #75, #76, #438, #439, #474)
• Fixed conflict with REST API caching plugins — POS requests could break entirely when a REST API caching plugin was active, this is now resolved (#421)
• Fixed expired JWT overriding valid authentication — an expired token could silently override a valid cookie session, locking users out unnecessarily (#472)
• POS discounts no longer wiped by coupons — applying a coupon to an order with POS-discounted items no longer resets those discounts back to the original price (#464)
• Fixed misc products showing $0 on receipts — miscellaneous products now display the correct price on receipts and order emails (#436)
• Fixed checkout-to-receipt navigation — no more crashes or lost order links when completing a sale (#77)
• Fixed token refresh on 403 errors — sessions that appeared “stuck” requiring a re-login should now refresh automatically (#74)
• Fixed store switching issues — switching between stores no longer causes errors or blank screens (da8c05d)
• Fixed missing data in received template — the order received page was missing link data, now restored (#476)
• Tightened permission checks — capability checks now properly match what’s configured on the Access settings page (#467)
• Improved performance during large syncs — the UI stays responsive while syncing large product catalogs (8657e1f)
• Fixed web hydration in standalone mode — the web app loads correctly when accessed directly without the desktop wrapper (#19)
