+### update:
+- 请求解析接口时遇到的错误输出到log，不返回msg
+<!-- - 服务端返回音质列表(需更新脚本) -->
+### feature:
+- 添加kg试听源(不计入缓存) **\*(需更新脚本)**
+- 注：部分歌曲只能试听前1分钟内容，无法试听的无法播放
+- (请手动删除 `data/public` 目录后启动程序重新释放静态资源)
+- 脚本还是 `data/public/lx-coustom-source.js`，开了Key验证的记得将原apipass复制过去
+### bugfix:
+- 修复wy源返回错误判断逻辑
+<!-- + [msg] 当前api结构与动态链实现方式不兼容，需要大改，故推迟更新 -->
+
 #### 2023-12-22 v1.0.2-b0.4 (beta)
 <!-- + 没有功能更新，几个未来的想法
