The main contents are as follows: 1. Adjust the frame structure, which is composed of one file divided into multiple files. Each of the divided files is determined by its function. Jfocus.system.tween.js, for example, contains all the features related to transition animation. It is more convenient for developers to use the framework on demand.

2. Optimize the core function of the framework, remove the unnecessary styling functions in DisplayObject, such as backgroundImage, textColor, etc., and use CSS style to describe or call styel or cssClass in DisplayObject object to dynamically modify the style. The visual object redrawing function is optimized and the code redundancy is reduced.

3. The availability of code smart prompts has been improved. In the previous version, a large number of private attributes will affect the readability of developers in smart prompts. In this version, code optimization has been carried out to eliminate some private attribute display problems.

4. Compatible with IE6 browsers. Some of the features reported in the previous version in IE6 browsers have been fixed in this version.
