+## [1.0.37] - 2026-06-15
+
+### 新功能
+- 库存查询新增「规格」和「系列」筛选，支持多选，按服务端过滤全量数据
+- 库存查询新增「入库时间」列
+- 入库单商品明细将「生产日期」移至主行直接可见，无需展开隐藏区域
+
+### 改进
+- 筛选弹窗重构：顶部搜索框实时过滤、选项列表可滚动、已选项以标签形式置顶显示并可单独取消
+- 筛选图标改为常驻显示，无需鼠标悬停
+
+### 修复
+- 修复商品系列批量导入被截断至 100 条的问题
+
+## [1.0.36] - 2026-06-13
+
+### 修复
+- 修复数据库初始化时 license_key 索引超长导致启动失败的问题
+
+## [1.0.35] - 2026-06-12
+
+### 改进
+- Debug 版本窗口标题增加 [DEBUG] 后缀，便于与正式安装版区分
+
+## [1.0.34] - 2026-06-12
+
+### 修复
+- 修复 macOS 客户端打印时应用卡死、只能强制退出的问题
+
+### 改进
+- 「关于我们」中「打开文档」「更新日志」等链接指向新域名 jiu.51yanmei.com
+
+## [1.0.33] - 2026-06-12
+
+### 改进
+- macOS 客户端插件集成从 CocoaPods 迁移至 Swift Package Manager，优化 macOS 构建流程
+
+## [1.0.32] - 2026-06-11
+
+### 修复
+- 修复库存可用量检查在数据库查询失败时误报所有商品库存不足的问题
+- 修复授权信息页面设备数量统计不准确的问题
+- 修复对账接口在数据库查询出错时静默返回空结果、掩盖异常的问题
+- 修复 license 验证缺少门店隔离过滤，提升多租户安全性
+- 官网联系入口调整为微信咨询（填写微信号后自动生效），隐藏尚未申请的备案号
+- 修复各接口分页大小未设上限，防止超大请求拖慢服务
+
+### 改进
+- 后端启动不再执行拼音回填，已改为独立工具（`cmd/backfill-pinyin`），避免大库存量时延长启动时间
+- 数据库连接池参数（最大空闲连接数、最大打开连接数）改为配置项，支持按环境调整

+# 酒库管理系统 — Gemini 编码规则
+
+## 项目背景
+
+这是一个多租户酒类库存管理系统，Go 后端 + Flutter 前端。
+
+## 强制规则（违反即重写）
+
+### 多租户隔离
+- `shop_id` **永远**从 `middleware.GetShopID(c)` 获取
+- **绝不**从 request body、URL params、query string 读取 shop_id
+- 所有数据库查询必须带 `WHERE shop_id = ?` 条件
+
+### 并发安全
+- 同一事务内读后写必须用 `FOR UPDATE` 锁行：
+  ```go
+  tx.Set("gorm:query_option", "FOR UPDATE").Where(...).First(&model)
+  ```
+- 适用：单号生成、库存扣减、任何 check-then-act 模式
+
+### 代码风格（参考 handler/product.go）
+- Handler 函数签名：`func (h *Handler) ActionName(c *gin.Context)`
+- 统一错误返回：`c.JSON(http.StatusBadRequest, gin.H{"error": "..."})`
+- 成功返回：`c.JSON(http.StatusOK, result)`
+- 所有 DB 操作通过 `h.db`，不直接引用全局变量
+
+### Schema 管理
+- 表结构变更同步修改 `backend/schema/schema.sql`
+- 无单独迁移文件，启动时 AutoMigrate
+- 不为单个字段加新列，用 `custom_fields JSON` 扩展
+
+### 测试规范
+- 测试文件放在同包下：`xxx_test.go`
+- 使用 `testutil/` 下的辅助函数
+- 每个 handler 至少覆盖：正常路径 + 缺少 shop_id 的 403 场景
+
+## 参考文件
+- Handler 模式：`backend/internal/handler/product.go`
+- Model 模式：`backend/internal/model/product.go`
+- 认证中间件：`backend/internal/middleware/auth.go`
+- Schema：`backend/schema/schema.sql`

+# 库存查询「规格」「系列」列头筛选 — UI 变更规范
+
+**变更类型**：简单变更，flutter-coder 可直接实现
+**对应文件**：`client/lib/screens/inventory/inventory_list_screen.dart`
+
+---
+
+## 复杂度判断
+
+复用现有 `FilterableColumnHeader` 组件，实现方式与已有「仓库」列筛选完全一致，无新组件、无新页面、无复杂交互，属于简单变更。
+
+---
+
+## 变更详情
+
+### [UI-001] 新增 State 变量
+
+**位置**：`_InventoryListScreenState` 类顶部，紧跟 `_filterWarehouse` 声明之后
+
+```dart
+Set<String> _filterWarehouse = {};
+Set<String> _filterSpec = {};      // 新增：规格筛选
+Set<String> _filterSeries = {};    // 新增：系列筛选
+```
+
+---
+
+### [UI-002] 派生筛选选项
+
+**位置**：`_buildInventoryTab()` 方法内，`data:` 回调中，紧跟 `warehouseOptions` 和 `filteredItems` 的现有代码之后替换
+
+**现有代码段（第 368-379 行）：**
+
+```dart
+final warehouseOptions = items
+    .map((i) => i.warehouseName)
+    .where((s) => s.isNotEmpty)
+    .toSet()
+    .toList()
+  ..sort();
+final filteredItems = _filterWarehouse.isEmpty
+    ? items
+    : items
+        .where((i) => _filterWarehouse.contains(i.warehouseName))
+        .toList();
+```
+
+**替换为：**
+
+```dart
+final warehouseOptions = items
+    .map((i) => i.warehouseName)
+    .where((s) => s.isNotEmpty)
+    .toSet()
+    .toList()
+  ..sort();
+
+final specOptions = items            // 新增：规格选项
+    .map((i) => i.spec)
+    .where((s) => s.isNotEmpty)
+    .toSet()
+    .toList()
+  ..sort();
+
+final seriesOptions = items          // 新增：系列选项
+    .map((i) => i.series)
+    .where((s) => s.isNotEmpty)
+    .toSet()
+    .toList()
+  ..sort();
+
+// 三个筛选叠加（AND 逻辑）
+final filteredItems = items.where((i) {
+  if (_filterWarehouse.isNotEmpty && !_filterWarehouse.contains(i.warehouseName)) {
+    return false;
+  }
+  if (_filterSpec.isNotEmpty && !_filterSpec.contains(i.spec)) {
+    return false;
+  }
+  if (_filterSeries.isNotEmpty && !_filterSeries.contains(i.series)) {
+    return false;
+  }
+  return true;
+}).toList();
+```
+
+**说明：**
+- 选项数据从当前页已加载的 `items` 派生，客户端筛选，与「仓库」逻辑一致
+- 三个筛选条件为 AND 叠加（同时满足才显示）
+- 空集合（`isEmpty`）视为「不筛选该维度」，等同于全选
+
+---
+
+### [UI-003] 替换「规格」和「系列」列头
+
+**位置**：`columns:` 列表中第 491-494 行（当前为 `const DataColumn`）
+
+**现有代码：**
+
+```dart
+const DataColumn(label: Text('规格')),
+const DataColumn(label: Text('系列')),
+```
+
+**替换为：**
+
+```dart
+DataColumn(
+  label: FilterableColumnHeader(
+    text: '规格',
+    options: specOptions,
+    selected: _filterSpec,
+    onChanged: (v) => setState(() => _filterSpec = v),
+  ),
+),
+DataColumn(
+  label: FilterableColumnHeader(
+    text: '系列',
+    options: seriesOptions,
+    selected: _filterSeries,
+    onChanged: (v) => setState(() => _filterSeries = v),
+  ),
+),
+```
+
+**注意**：移除原来的 `const` 关键字，因为构造函数参数不再是编译期常量。
+
+---
+
+## 视觉规范（无需改动）
+
+`FilterableColumnHeader` 的所有视觉行为保持原样：
+
+| 状态 | 表现 |
+|------|------|
+| 默认（无筛选） | 纯文字列头，无图标 |
+| Hover | 显示半透明 `filter_alt_outlined` 图标（灰色）|
+| 已激活筛选 | 图标变为实心 `filter_alt`（主色 #1565C0）+ 右侧出现 X 清除按钮 |
+| X 按钮点击 | 清空该维度筛选（`onChanged({})` ），无需打开弹窗 |
+| 列头点击图标 | 弹出 `_MultiSelectDialog`（全选/清空 + checkbox 列表 + 取消/应用） |
+
+---
+
+## 受影响范围
+
+- 仅修改 `_InventoryListScreenState` 内部，不涉及 provider、model、API
+- `_buildWarningTab()` 和 `_buildLogTab()` 不受影响
+- 导出 Excel 的 `filteredItems` 自动受益于新筛选逻辑，无需额外改动
+- 窄屏卡片流（`mobileCards`）同样使用 `filteredItems`，筛选效果自动生效
