Last February, we released the first beta of jQuery 4.0.0. We’re now ready to release a second, and we expect a release candidate to come soon™. This release comes with a major rewrite to jQuery’s testing infrastructure, which removed all deprecated or under-supported dependencies. But the main change that warranted a second beta was a fix to the exports field for bundlers. More on that and other changes below. Many of the breaking changes in jQuery 4.0.0 are ones the team has wanted to make for years, but couldn’t in a patch or minor release. We’ve trimmed legacy code (including removing support for IE before version 11), removed some previously-deprecated APIs, removed some internal-only parameters to public functions that were never documented, and dropped support for some “magic” behaviors that were overly complicated.
