# Important: #68917 - Updated jQuery to 2.x

See [forge#68917](https://forge.typo3.org/issues/68917)

## Description

With the step from jQuery 1.x to 2.x support for older browsers and "dirty workarounds"
have been dropped. Since TYPO3 CMS doesn't support "older" browsers (IE < 9) anymore, jQuery
was updated from 1.x to 2.x. For extensions that ran fine with an up-to-date 1.x-version
that shouldn't really make much difference. There might however be edge-cases where
extension-authors might need to adapt their jQuery scripts for 2.x.
