We weren’t here to report it in real-time, but on February 6, jQuery Core Team Lead Timmy Willison announced that jQuery 4.0.0 is now available in beta.
jQuery 4.0.0 has been in the works for a long time, but it is now ready for a beta release! There’s a lot to cover, and the team is excited to see it released. We’ve got bug fixes, performance improvements, and some breaking changes.
We’ve trimmed legacy code, 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.
