It’s amazing what you find when you read the documentation. Since I always forget the address for Google’s CDN hosting of jQuery I have to search for it each time. This time when I found the address I was looking around a bit and found out this interesting tidbit that I didn’t know before about Google’s CDN for their AJAX libraries.
Specifying a version of “1.8.2″ will select the obvious version. This is because a fully specified version was used. Specifying a version of “1.8″ would select version 1.8.4 since this is the highest versioned release in the 1.8 branch. For much the same reason, a request for “1″ will end up loading version 1.9.1.
