But in 2009, many people were using browsers that lagged behind the leading edge. In order to reach the broadest base of users, developers often had to either build multiple versions of their applications or not use the new capabilities at all. We created Chrome Frame — a secure plug-in that brings a modern engine to old versions of Internet Explorer — to allow developers to bring better experiences to more users, even those who were unable to move to a more capable browser.Today, most people are using modern browsers that support the majority of the latest web technologies. Better yet, the usage of legacy browsers is declining significantly and newer browsers stay up to date automatically, which means the leading edge has become mainstream.
Given these factors we’ve decided to retire Chrome Frame, and will cease support and updates for the product in January 2014.
My sites opt into Chrome Frame withchrome=1
in theX-UA-Compatible
meta tag or HTTP header.
- If you don't require Chrome Frame to use your content, you can remove these opt-in headers now, and slim down the bytes sent to users.
Since IE 6/7/8 are still relatively common, we recommend using the 1.x version unless you are certain no IE 6/7/8 users are visiting the site.
So, jQuery 2.x is an optimization for situations where you can be sure you have a modern browser.jQuery 2.x has the same API as jQuery 1.x
