+## [1.0.66] - 2026-06-21
+
+### 改进
+- 入库/出库列表「日期」列改名为「入库时间/出库时间」，移除恒为空的旧「审核时间」列
+- 日期选择改为可直接键入的输入框 + 日历图标：能直接打年份（选老年份方便），支持只填到年或年月（自动补为月初）
+
+## [1.0.65] - 2026-06-21
+
+### 改进
+- 入库录入改为「每行一个独立产品」：每条明细对应一个独立编号，同名同规格录多次也各自独立（配合后端 server-v1.0.69）

+### 改进
+- 入库录入改为「每行一个独立产品」：每条明细新建独立商品、发独立序列号（同名同规格录多次也各自独立），不再复用已有商品编号，符合"每个货品一个唯一编号"的管理方式
+
+## [1.0.68] - 2026-06-21

+### 修复
+- 根治商品编码可能重复的问题：自动编码改为按现有最大序号递增生成（不再复用已删除商品占用过的编号、并发下也不会撞号），并在数据库层为「同门店 + 编码」加唯一约束，从此重复编码无法静默产生
