JQuery is a popular, fantastically useful, and not to mention powerful, Javascript library used by many web applications around the Internet.
The current version of it is 1.9.1, but unfortunately the latest release of Elgg is still tied to a frankly ancient version (1.6).
Recently, I needed a more recent version of jquery in order to take advantage of the Bootstrap framework. So I put together a quick plugin which lets you easily use the latest version of JQuery in Elgg.
This saved me from a number of headaches, and I hope it’ll do the same for you.
Enjoy!
