Is there a link to the "latest" jQuery library on Google APIs?

Up until jQuery 1.11.1, you could use the following URLs to get the latest version of jQuery:

• https://code.jquery.com/jquery-latest.min.js - jQuery hosted (minified)
• https://code.jquery.com/jquery-latest.js - jQuery hosted (uncompressed)
• https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js - Google hosted (minified)
• https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js - Google hosted (uncompressed)

For example:

<script src="https://code.jquery.com/jquery-latest.min.js"></script>

---

However, since jQuery 1.11.1, both jQuery and Google stopped updating these URL's; they will forever be fixed at 1.11.1. There is no supported alternative URL to use. For an explanation of why this is the case, see this blog post; Don't use jquery-latest.js.

Both hosts support https as well as http, so change the protocol as you see fit (or use a protocol relative URI)

DO NOT USE THIS ANSWER. The URL is pointing at jQuery 1.11 (and always will).

http://code.jquery.com/jquery-latest.min.js is the minified version, always up-to-date.

Be aware that caching headers are different when you use "direct" vs. "latest" link from google.
