+# 接口变更记录 — 2026-04-13
+
+> **变更类型**：BUG修复
+> **影响接口**：产品线分页列表、产品线详情
+
+---
+
+## 产品线 seasons/tags 返回格式修复
+
+### 问题
+
+产品线列表和详情接口的 `seasons` 和 `tags` 字段返回的是 JSON 字符串而非数组：
+
+```json
+// 修复前（错误）
+"seasons": "[\"spring\", \"summer\", \"autumn\", \"winter\"]",
+"tags": "[\"自驾\", \"高原\", \"摄影\", \"可亲\"]"
+
+// 修复后（正确）
+"seasons": ["spring", "summer", "autumn", "winter"],
+"tags": ["自驾", "高原", "摄影", "可亲"]
+```
+
+### 影响接口
+
+| 方法 | 路径 | 说明 |
+|------|------|------|
+| GET | `/admin/product/line/list` | 产品线分页列表 |
+| GET | `/admin/product/line/{lineId}` | 产品线详情 |
+
+### 修复状态
+
+代码已修复，等待下次部署生效。
