@ColibriMedia it’s a more-specific pattern of use than that.

I made a code sandbox to be able to test jQuery code between the two versions: boring-butterfly-17ns5 - CodeSandbox

anybody can use that as a starting place to test custom code that you might be worried about. You can see the different jQuery versions pulled in at the end of the two html files.

With 3.4.1

$("<div/><div/>") becomes <div></div><div></div> (fragment with two divs):

With 3.5.1

$("<div/><div/>") becomes <div><div></div></div> (nested):

Hey there!
I just started working with webflow, and I used one of the templates on the website.
When I checked my website in PageSpeed Insights I saw that the jQuery version is 3.4.1 and not the latest. How can I upgrade it?
Thanks!
