+## [0.1.12] - 2026-08-23
+
+### 变更
+
+- 全平台启动时强制禁用 Electron GPU 硬件加速，降低后台网页 renderer 的无效显存与内存占用。
+
+## [0.1.11] - 2026-08-23
+
+### 变更
+
+- 切换后端时销毁非当前后端的网页窗口，保留登录会话但不再保活其 renderer。
+- 移除悬浮球点击录音和常驻显示功能，悬浮球仅用于显示语音会话状态。
+- 缩短正常完成后的绿色状态显示时间。

 ### 本项目暂不考虑迁移到Tauri。我们充分理解这种需要后台常驻的系统性应用，在Tauri下开发似乎更加合适，事实上我们也确实进行了两次Tauri迁移。但元宝和千问web版对于webkit2gtk的表现实在是过于糟糕了（至少是在我的目标设备上），即使使用默认的gnome浏览器进行语音输入都会卡死，更不用说后续自动化的抓取了。还请各位理解，该项目是一个偏个人向的项目（毕竟使用的这种方式，大规模公开那就是商业侵权），而我的目标开发设备是一台非常老旧的设备，我没法说因为为了在他人的设备上获得更出色的性能而放弃对自己设备的适配。也许未来我们会在这些web端的兼容性得到改善，或者该目标设备被淘汰以后，才会考虑向Tauri迁移。

 ### 项目暂不支持豆包后端。豆包的ASR输入是直接发送请求，而非像元宝和千问一样输出到输入框，这就需要拦截或自行重新实现请求，技术难度高且有风控风险。
 
 ### 同时该项目是中文输入主导的，也不考虑适配chatgpt等非中文优先的平台。
