jQuery UI 1.14.2 Changelog

Released on January 29, 2026

link Supported jQuery versions

This release has been tested against jQuery 1.12.4, 2.2.4, 3.6.4, 3.7.1 & 4.0.0. Since jQuery follows semver, newer jQuery <5 versions within each major version line should generally work as well.

jQuery UI 1.14.2 triggers no jQuery Migrate messages except for its initialization one when running its test suite against jQuery 4.0.0 with jQuery Migrate 4.0.2 or jQuery 3.7.1 with jQuery Migrate 3.6.0, i.e. the latest versions at the time of this release.
