Gift with Purchase

Fixed

• Fixed gift discount calculation for customers with different tax rates (e.g. German 19% vs French 20%). The discount now accounts for tax adjustments so the line item total is correct regardless of whether prices include tax.

Changed

• Replaced "Gift Price" (absolute price override) with "Gift Discount %" (percentage discount, 100% = free by default).
• Gift line items now show the original product price; the discount is applied as a Commerce order adjustment labeled "Offered".
• Tax calculations now use Commerce's built-in discount logic instead of manual price overrides.
• Registered custom GiftDiscountAdjuster via Commerce's EVENT_REGISTER_ORDER_ADJUSTERS.

Removed

• Removed giftPrice field (replaced by giftDiscountPercent).
• Removed giftValue (declared value) field — no longer needed since original prices are preserved.
• Removed EVENT_POPULATE_LINE_ITEM price override handler.

Changed

• Updated for Craft CMS 5 and Craft Commerce 5 compatibility.
• Requires PHP 8.2+.
• Replaced salePrice with promotionalPrice for gift line item pricing (Commerce 5).
• Updated createLineItem() calls to use the new Commerce 5 signature.
• Replaced getProduct() with getOwner() for variant parent lookups (Commerce 5).
• Currency formatting in the control panel now uses the store's default currency instead of hardcoded EUR.
• Removed static $plugin singleton in favor of getInstance().

Added

• Gift rule management with full control panel UI (create, edit, reorder, bulk enable/disable/delete).
• Condition-based triggers: cart subtotal (min/max), specific purchasables, product categories, date ranges, and user groups.
• Automatic gift addition and removal based on cart state.
• Gift price override (free, discounted, or fixed amount).
• Optional line item note on gift products.
• Auto-add and re-add on removal behavior options.
• User group targeting (Craft Pro).
• Date scheduling for time-limited promotions.
• Drag-and-drop rule priority ordering.
• Gift price persistence through Commerce recalculations via EVENT_POPULATE_LINE_ITEM.
• Custom events: EVENT_BEFORE_SAVE_GIFT_RULE, EVENT_AFTER_SAVE_GIFT_RULE, EVENT_AFTER_DELETE_GIFT_RULE.
