+## [1.0.72] - 2026-06-22
+
+### 新功能
+- 出库单录入新增「售价」可编辑列：可按实际销售价录入，金额与单据应收按「售价 × 数量」实时计算，同时保留成本价一栏便于对比
+
+### 改进
+- 「退单」按钮改为红色实心样式，更醒目地突出该危险操作（与原型一致）
+- 库存列表隐藏「库存量」列：序列号模型下每件商品独立，原数量列易受历史数据误导，故不再展示（缺货/预警逻辑不受影响）
+- 出库「添加商品」可一次看到整仓商品（需配合后端 v1.0.75）

+## [1.0.75] - 2026-06-22
+
+### 新功能
+- 出库单新增「售价」字段：可按实际销售价录入，应收账款改为按「售价 × 数量」计算，更真实地反映销售额（此前应收按成本价计）。
+
+### 修复
+- 修复出库单「添加商品」选择器只能看到一小部分商品的问题：库存查询接口的分页上限此前会把超额请求打回，导致选货时只显示约 20 条，现已放宽，可一次加载整仓商品。
