 ### 历史更新记录
 
+> 2020年12月27日 ：
+
+2020年年终大版本更新，架构全面设计，代码全面重构，代码质量全面提升，二次开发更便捷，欢迎拉源码品鉴，提issue、pr共同建设
+
+1. 架构模块调整,大量的代码重构，代码质量提升N个等级，欢迎品鉴
+2. 增强XML文件预览效果，新增XML文档数结构预览
+3. 新增markdown文件预览支持，预览支持md渲染和源文本切换支持
+4. 切换底层web server为jetty，解决这个issue：https://github.com/kekingcn/kkFileView/issues/168
+5. 引入cpdetector，解决文件编码识别问题
+6. url采用base64+urlencode双编码，彻底解决各种奇葩文件名预览问题
+7. 新增配置项office.preview.switch.disabled，控制offic文件预览切换开关
+8. 优化文本类型文件预览逻辑，采用Base64传输内容，避免预览时再次请求文件内容
+9. office预览图片模式禁用图片放大效果，达到图片和pdf预览效果一致的体验
+10. 直接代码静态设置pdfbox兼容低版本jdk，在IDEA中运行也不会有警告提示 
+11. 移除guava、hutool等非必须的工具包，减少代码体积
+12. Office组件加载异步化，提速应用启动速度最快到5秒内
+13. 合理设置预览消费队列的线程数
+14. 修复压缩包里文件再次预览失败的bug
+15. 修复图片预览的bug
+
 > 2020年05月20日 ：
 1. 新增支持全局水印，并支持通过参数动态改变水印内容
 2. 新增支持CAD文件预览
