Vue.js 轻量级 JavaScript 框架
Vue.js 是构建 Web 界面的 JavaScript 库，提供数据驱动的组件，还有简单灵活的 API，使得 MVVM 更简单。
轻量级 JavaScript 框架 Vue 2.1.7 发布了。
为了修复一些错误，不得不介绍一些小的行为更改。
如果你是一个提供预编译的 dist 文件d的插件/组件的作者
It is recommended to re-compile the dist file using the latest versions of vue-template-compiler and vue-template-es2015-compiler. The new generated code is backwards-compatible, but code generated by older versions of the compilers may not work properly with the latest runtime.
Code generation changes that affect compatibility are very rare and we will avoid introducing similar changes in future patch releases.
如果使用<transition-group>的移动动画功能： you use <transition-group>'s move animation feature:
When fixing #4510 (ensure leave transitions and enter transitions triggered by the same state change are started in the same frame), we had to move the application of the v-enter-active and v-leave-active classes to one frame after the application of v-enter and v-leave. This should not affect existing usage of <transition>, however if you are using <transition-group> for moving animations, there is a minor adjustment required: you need to now add position: absolute to both v-leave and v-leave-active (previously only v-leave-active is sufficient). See updated moving animation example.
Improvements
Improved stateful components instantiation performance by ~30%.
From version 2.1.7 and up, you can directly use the CDN link https://unpkg.com/vue for the standalone build.
