 最新讯息：
+### 关于打包下载功能的细节调整
++ 在打包下载时，ZIP的压缩时间比较长，这回导致用户误以为系统崩溃。现在为压缩过程增加了提示信息。另外，本应用内置的ZIP压缩方式在压缩100MB以上的文件时所用时间会明显变长。原本计划打包下载就是为了给碎片化文件一次性下载准备的，并未考虑到压缩大文件，因此效率不高。在本人找到更好的压缩算法并更新前，请不要对太大的文件进行打包下载（虽然不会崩溃，但压缩时间会很长）。

 ### 关于windows下安装方法的修正：
 + 本人在Windows虚拟机上进行了模拟安装测试，并发现了之前很多用户反馈闪退问题的根本原因：安装java不会在系统中自动增加JRE_HOME环境变量。这导致kiftd根本无法找到java运行环境，出现闪退。目前本人已经紧急更新了windows下的安装流程并详细说明，为您带来的不便深感歉意！详见《说明文档》。
