v3.8.2

2017-11-10

• [^] Fixed backward compatibility problems brounght by 3.8.0:
  • In 3.8.0, the content in lib directory is the same as the content in src directory (both are ES Module), which may not compatible with the old verisons of node and webpack. So rollback to commonJS format in lib of 3.8.2.
  • In 3.8.0, the source code in src constains global variable __DEV__ (which prints dev helper info for echarts users). To get the declaration of the global variable, users should include echarts/src/config.js manually or make some settings in webpack/rollup (Check custom build tutorial please), which is not backward compatible. So we have removed __DEV__ from the codes in echarts/lib/** in 3.8.2. If dev helper info is required, use codes in echarts/src/**.
  • After 3.8, echarts/src/echarts.js (the same as echarts/lib/echarts.js in 3.8.0) does not include util methods, which used to be mounted on it. Now util methods are listed in echarts/src/export and mounted on echarts/echarts*.js. But it is not backward compatibility, so we have rollbacked to mount them on echarts/lib/echarts.js in 3.8.2.
  • The way of including echarts/extension/dataTool, havs been rollbacked to the original approach before 3.8, where it must be included explicitly, and the namespace will be mounted on echarts namespame.
• [^] Fixed the problem that SVG renderer throws error when encounter null value.

• Changes about dataTool: When using dist/echarts/echarts.simple.js or dist/echarts/echarts.common.js, dist/echarts/extension/dataTool.js should be manually included as before, but the namespace dataTool will not be mounted to echarts. When using dist/echarts/echarts.js, echarts.dataTool is included automatically by default.
