 jQuery 1.x supports IE 6/7/8 and jQuery 2.x does not 

jQuery 3.7.0 is now available! This release has it all: bug fixes, a new method, and a performance improvement! We even dropped our longtime selector engine: Sizzle. Or, I should say, we moved it into jQuery. 

jQuery 3.0 is the future. If you need IE6-8 support, you can continue to use the latest 1.12 release.

jQuery 3.6.0 has been released! In jQuery 3.5.0, the major change was a security fix for the html prefilter. This release does not include a security fix, but does have some good bug fixes and improvements. We still have our eyes on a jQuery 4.0 release, but until then we will continue to support the 3.x branch and address important issues. 

jQuery has a new release! It’s been a while since our last release, but we expect this to be the last minor release in the 3.x branch, and then we will move on to the overhaul that will be jQuery 4.0. But before we get to 4.0, we’re excited to share the bug fixes and improvements included in jQuery 3.4.0
