 # Changelog - Website Sale Aplicoop
 
+## [18.0.1.9.0] - 2026-05-20
+
+### Added
+
+- **Category sequence**: New `sequence` field on `product.category` for controlling product display order on the web shop. Migration adds the column with default 10.
+- **Stock availability check on history orders**: When loading a historical order, products are validated against current stock (`virtual_available`). Out-of-stock items are flagged before adding to cart.
+
+### Changed
+
+- **Cart disabled / redirected to /eskaera**: Standard `website_sale` cart is fully hidden — header cart icon removed, add-to-cart buttons removed from standard shop, `/cart` and `/shop` routes redirect to `/eskaera`. Customers interact exclusively through the group order flow.
+- **Product card UI overhaul**: Improved responsive layout, placeholder image for products without photo, better accessibility markup, and professional styling for mobile.
+- **Stock check uses `virtual_available`**: Replaces `qty_available` so forecasted quantity (including incoming moves) is considered.
+
+### Fixed
+
+- Lint fixes: exception chaining (`raise ... from exc`), unused imports/vars, `disable attribute-string-redundant` annotations.
+
+---
+
+## [18.0.1.8.0] - 2026-04-08
+
+### Added
+
+- **Clear cart button**: New button in the sidebar to empty the current group order cart in one click (`eskaera_clear_cart` route).
+
+### Changed
+
+- **Portal access restricted to consumer group**: Portal users can only see group orders belonging to their consumer group. Security rule `rule_group_order_company_read` updated with `user.share` guard.
+- **Controller filtering by consumer group**: `eskaera_list` and `eskaera_shop` routes filter orders by the logged-in user's consumer group, not just by company.
+
+### Fixed
+
+- Stale cart invalidation: carts linked to closed/cancelled group orders are cleared on next access.
+- Home delivery draft flow: fixed state transition for home delivery orders.
+- Auto-confirm `sale.order` on cutoff day: fixed off-by-one (`>` vs `>=`) in cutoff guard so orders on the cutoff day are correctly confirmed.
+- Pickup dates frozen after cron confirm: cron no longer overwrites pickup dates on already-confirmed orders.
+- Cron hardened against missing/invalid group order configurations.
+- Cart layout: moved cart sidebar before product grid.
+- i18n: added missing ES/EU translations for checkout, cart labels, Save Draft button, and weekday strings. Removed legacy `week_draft` translation keys.
+
+---
+
+## [18.0.1.7.0] - 2026-03-06
+
+### Added
+
+- **Automatic batch picking creation**: After the cutoff cron confirms sale orders, picking batches are automatically created grouped by consumer group and pickup date.
+- **Consumer group propagation**: `consumer_group_id` is now propagated directly from the `group.order` to linked `sale.order` records, eliminating manual assignment.
+- **Out-of-stock blocking**: Add-to-cart button is hard-disabled for out-of-stock products. `allow_out_of_stock_order` flag on product is respected.
+
+### Changed
+
+- **Cron auto-confirm sale orders**: Daily cron (`_cron_confirm_group_orders`) now confirms linked sale orders on the cutoff date instead of requiring manual action.
+- **Order card meta extracted**: Order card metadata (dates, state badge) moved to a reusable `_eskaera_order_card_meta` template for cleaner rendering.
+- Delivery toggle (reparto/envío a domicilio) wired directly from the cart sidebar.
+- Pricing alignment: theoretical price and displayed price reconciled for orders with home delivery.
+
+### Fixed
+
+- Fixed broken `aplicoopShop` → `groupOrderShop` JS class reference.
+- Ensured add-to-cart event listeners are re-attached after infinite scroll loads new products.
+- i18n: translated weekday names (ES/EU).
