It [has come to our attention⁠](https://github.com/transloadit/jquery-sdk/issues/13) that when[upgrading your jquery-rails gem⁠](https://github.com/transloadit/rails-sdk/issues/33) (or using other means of upgrading to jQuery 1.9 anyway), our[jQuery SDK⁠](https://github.com/transloadit/jquery-sdk) had some compatibility issues (`$.browser`doesn't exist anymore in jQuery 1.9 which was required by one of our components).

Since this could potentially cause problems, we released new versions of our jQuery SDK here. We[introduced versioning⁠](https://github.com/transloadit/jquery-sdk/commit/e4d3ff8265f45bdb5d008ab3ad29382c30f1f095)because upgrading to `latest` also means dropping support for Internet Explorer 6.0. We will leave the choice up to you to:

* Always be on the latest version we offer for API2:[https://assets.transloadit.com/js/jquery.transloadit2-latest.js⁠](https://assets.transloadit.com/js/jquery.transloadit2-latest.js) (jQuery 1.9, No IE6) (this could automatically upgrade you to backwards breaking versions)
* Always be on the latest v2 for API2:[https://assets.transloadit.com/js/jquery.transloadit2-v2-latest.js⁠](https://assets.transloadit.com/js/jquery.transloadit2-v2-latest.js) (jQuery 1.9, No IE6) (recommended)
* Pinpoint to this release, and do not receive any surprise updates:[https://assets.transloadit.com/js/jquery.transloadit2-v2.0.0.js⁠](https://assets.transloadit.com/js/jquery.transloadit2-v2.0.0.js) (jQuery 1.9, No IE6)
* Stay with the old version for now: [https://assets.transloadit.com/js/jquery.transloadit2.js⁠](https://assets.transloadit.com/js/jquery.transloadit2.js) (No jQuery 1.9, IE6)

Hope this helps!
