TinyMCE 4.0.12 版本发布，是一个 bug 修复版本。
修复的 bugs：
Fixed bug that WebKit/Blink has had for years where it generates span elements all over the content with the current runtime styles of the elements. We had to override all the possible scenarios where contents is deleted and make sure it didn't generate these spans when those operations occurred.
Fixed a few paste related issues such as IE not being able to paste contents when specific security settings where used. Firefox/Chrome now filters drag/dropped contents from external sources with the paste filters. IE doesn't have proper API support yet to enable that feature.
TinyMCE是一个轻量级的基于浏览器的所见即所得编辑器，支持目前流行的各种浏览器，由JavaScript写成。功能配置灵活简单（两行代码 就可以 将编辑器嵌入网页中），支持AJAX。另一特点是加载速度非常快，如果你的服务器采用的脚本语言是 PHP，那还可以进一步优化。最重要的是，TinyMCE是一个根据LGPL license发布的自由软件，你可以把它用于商业应用。
