Released in jquery 2.0, and does not support IE 6/7/8

Jquery officially released jquery 2.0 today.

The main changes of this version are as follows:

• No longer supports IE 6/7/8If you use the "Compatibility View" Mode in ie9/10, it will also be affected.
• More lightweight, Version 2.0 is 12% smaller than version 1.9.1.
• ModularYou can build a smaller and lighter version.
• Compatible with APIs of jquery 1.9.

If you still have a large number of target users using IE 6/7/8, you should use jquery 1.9 in the project, or expect the coming version 1.10 in two months.

Because this version has changed a lot, if you upgrade from a version earlier than 1.9 to this version, we recommend that you use the jquery migration plug-in and read the jquery 1.9 upgrade guide.

Details: jquery 2.0 released

For jquery 2.0 to abandon support for IE 6/7/8, see what the official saying: jquery officially answers the user's question (note the last one)

However, the problem is that IE6 was still strong 10 years after its birth, especially in China, with a 25.8% share of IE6, the largest in the world. Do you dare to use jquery 2.0 for Web developers in China?
