+## 最新适配
+
+- `wx.app 4.1.8.27 (36559)` 下载地址：
+  `https://dldir1v6.qq.com/weixin/Universal/Mac/xWeChatMac_universal_4.1.8.27_36559.dmg?t=1770782406`
+- 本次变更仅做了两类最小补充：
+  - `config.json` 新增 `36559` 的 x86_64 防撤回和多开配置
+  - patch 流程新增 `target.binary` 支持，可直接对 `Contents/Frameworks/wechat.dylib` 打补丁；旧版构建产物只会 patch `Contents/MacOS/WeChat`，不适用于这一版
+
