jQuery is still actively in-use across plenty of websites on the Internet – currently in use on 64% of the top million websites. The development team announced yesterday the launch of jQuery 3.0 Alpha. The new version is supported by all modern browsers – including the Yandex Browser from now on.
The new HTML5 dataset specification is now also properly supported via .data(), allowing easy access to all the data-* attributes nested inside an HTML element. This wasn’t a major overhaul, but only a few tweaks to make sure jQuery’s code is compliant with the official specification.
Changes to the .show() and .hide() methods were also included to help them work with responsive websites. The methods are now much simpler in their make-up, but they’re also going to be the main culprits if your code breaks when upgrading to the 3.x branch.
