jQuery 3.0 Final Released
Written by Alex Armstrong

jQuery 3.0 has officially arrived having been work in progress since October 2014. Despite being a new major version it is not expected to pose major compatibility issues and a migration plug-in and an upgrade guide are available to help with the transition.




The final version comes just a fortnight after the JQuery 3.0 Release Candidate which we covered in some detail.  

In the announcement of the final arrival of jQuery 3.0 on the jQuery blog Timmy Willison notes:

We set out to create a slimmer, faster version of jQuery (with backwards compatibility in mind). We’ve removed all of the old IE workarounds and taken advantage of some of the more modern web APIs where it made sense. It is a continuation of the 2.x branch, but with a few breaking changes that we felt were long overdue. 

As you will know the previous major version, jQuery 2.0, made breaking changes that didn't support older browsers. It was for this reason that the jQuery 1 branch continued to be supported. Similarly the 2.2 branch will continue to receive critical support patches but not any new features or major revisions.

The browsers supported by jQuery 3.0 are: 

  • Internet Explorer: 9+
  • Chrome, Edge, Firefox, Safari: Current and Current - 1
  • Opera: Current
  • Safari Mobile iOS: 7+
  • Android 4.0+ 

As jQuery team policy is to only change browser support on major-version updates, this list will apply until at least jQuery 4 arrives.

As well as giving details of the breaking changes, some of which we reported with reference to the Release Candidate, the brand new  jQuery Core 3.0 Upgrade Guide lists new features and ones that are deprecated. 

The Upgrade Guide also outlines the steps for using the jQuery Migrate Plugin as an upgrading tool which provides specific advice about how major changes may affect your existing code.
