-### 自定义源的不兼容变更与新增内容（源开发者需要看）
 
-自定义源的调用方式已改变：
+更新前需要注意：
 
-- 为了与移动端的调用方式统一，不再推荐使用 `window.lx` 对象（移动端无`window`对象），改用 `globalThis.lx`
-- `inited` 事件不再需要传递 `status` 属性，脚本运行过程中，在成功调用 `inited` 事件之前的任何首次未捕获的错误都将视为初始化失败，所以现在若想人为让脚本初始化失败，直接抛出一个错误即可
-- 新增 `globalThis.lx.env` 属性，桌面端环境固定为 `desktop`，移动端环境固定为 `mobile`
-- 新增 `globalThis.lx.currentScriptInfo` 对象，可以从这里获取解析后的脚本头部注释信息及脚本原始内容，具体可用属性看文档说明
-- `globalThis.lx.version` 属性更新到 `2.0.0`
+由于自定义源的调用方式变更，可能会导致某些第三方源停止工作，如果出现这种情况，你需要将LX回退到 v2.5.0
 
 ### 新增
 
@@ -45,3 +40,15 @@
 - 移除所有内置源，由于收到腾讯投诉要求停止提供软件内置的连接到他们平台的在线播放及下载服务，所以从即日（2023年10月18日）起LX本身不再提供上述服务
 - 更新 electron 到 v25.9.8
 - 更新许可协议的排版，使其看起来更加清晰明了，更新数据来源原理说明
