Update jQuery

[nilshoerrmann]

We should updated the bundled jQuery version to the latest release:

Needs some testing due to the API changes:

We may even consider jQuery 2.0, considering we aren't doing anything special to cater for IE6-8 :) IE8 is a bit of a concern though, worth testing to find out what exactly would/wouldn't work.

[nilshoerrmann]

Symphony 2.3 doesn't support IE8 due to HTML5 markup. So that shouldn't be a concern.

Sounds great!

jQuery's migrate plugin might be helpful to find issues:

Good idea, it will at least let us know what's wrong (if anything!)

[nilshoerrmann]

Is integration already for version 2.4 or is it still 2.3?
Could we bundle the migration script with 2.4dev so that this gets widely tested?

It will still be 2.3.2 as it's not released. I am waiting myself for it to be 2.4 ready so I can push a shed load of commits.

[nilshoerrmann]

What about creating a new branch for the 2.4 work?

[designermonkey]

I think I already suggested that and got told not to :(

[nilshoerrmann]

What's the logic behind that decision? @brendo?

[brendo]

Because we'll get distracted and won't deliver a 2.3.2.
