This is simply passing on a warning from the jQuery blog post entitled “Don’t Use
jquery-latest.js“. For some time now, the
jquery-latest.js file from their CDN has been heavily used and abused in production sites.
jquery-latest.js to jQuery 2.0 on behalf of older sites that would suddenly break because of the new Internet Explorer support limits. However, that has not stopped people from using it.
As jQuery usage increases and to prevent this abused file from “breaking the web”, from now on (when this news was reported on July 3), the
jquery-latest.min.js files have been locked to v1.11.1 forever. They will no longer be updated. Google has also joined in the efforts and locked their CDN equivalent to v1.11.1. Further more, a few members of the community and apparently the developers themselves have discussed adding some sort of warning to these files urging developers to no longer use them, an action I would support.
So what does this mean for you and what should be your reaction? Do not use the
jquery-latest.min.js files in development nor production sites. Instead, always use a version release from the CDNs (1.11.1 or 2.1.1). It is as simple as that.
So please, tell your developer friends about this and do yourself, them, and the entire Web a favor by never using these files again and updating any current sites to use a version release. 🙂
