It’s finally here! Well this was last week but there’s no harm in being excited. The big news is that jQuery 3.0 will become the only version of jQuery. The 1.12 and 2.2 branches will continue to receive critical support patches for a while, but will not get any new features or major revisions.

Despite the 3.0 version number, these releases shouldn’t be too much trouble when it comes to upgrading existing code. Don’t worry much on the complexity of migrating to the new version of jQuery,  the devs were fairly kind to provide a guide and also a plugin to check compatibility issues before you migrate your codes.

Note that jQuery 3.0 will not support IE6-8. If you need IE6-8 support, you can continue to use the latest 1.12 release.
