发行说明

本次更新主要添加了对 Linux 的帧缓存（FrameBuffer）的支持，在没有 Xwindow 服务支持的字符终端模式下，LCUI 会改用 Linux 的帧缓存来输出图形内容，并直接从鼠标设备（/dev/input/mice）和标准输入（stdin）中读取用户输入。不过，这些支持并不完善，而作者也没有打算继续完善这块功能，理由很简单：没什么用，懒得浪费时间。如果你有丰富的 Linux 开发经验，可以向此项目提供改进方案，与其他人分享你的技术。

LCUI 的源代码中还有很多待改进的代码，包括：打算改、没时间改、懒得改和不想改的代码，其中有一部分代码已经用 FIXME 注释标记，这些注释中有的会说明为什么改进它，以及怎么改进它，如果你感兴趣，可以留意源代码中的 FIXME 注释内容，或者直接搜索 FIXME 注释，看看有哪些是可以帮上忙的。
