jQuery Support

---

link Supported versions

We support only the latest version of jQuery. The 1.x and 2.x branches are no longer supported.

jQuery 3.x will only receive critical security patches and bug fixes. We encourage all users to upgrade to the latest version of jQuery 4.x.

jQuery 4.x is the current version branch of jQuery.

link Unsupported versions

When using a version earlier than the latest version, there are a few options:

• Upgrade to the latest version of jQuery. The best solution is to upgrade as it will include all features, bug fixes, security patches, and improvements. The jQuery Migrate Plugin and upgrade guides are available to assist with upgrading.
• Continue using an older version of jQuery, but include all security patches through commercial security support.
• Continue using an older version of jQuery without security patches. However, this can come with multiple risks.

link Community support

The following learning resources are available online and free of charge:

• jQuery Learning Center
• jQuery API Documentation
• jQuery UI Demos
• jQuery UI API Documentation

link Matrix chat

jQuery is on Matrix! The support channel for jQuery is #jquery_jquery:gitter.im. You can read the channel on Element without an account, or join the channel via any Matrix client.

We use the public #jquery_dev channel to discuss project developments. We also hold weekly meetings on Matrix.

link IRC chat

We are on Libera Chat IRC in the #jquery channel where you can ask for support. You can join via webchat, or via any IRC client.

link StackOverflow

StackOverflow is a great place to ask questions and find support for all jQuery projects. Search or create questions tagged with "jquery", or refer to the "jquery" tag introduction.

link Commercial support

Organizations that need support for older or unsupported versions of jQuery can work with commercial providers offering services such as security fixes, compatibility support, and extended lifecycle maintenance.

The OpenJS Foundation’s Ecosystem Sustainability Program (ESP) provides a framework for commercial support around end-of-life open source software. The program is non-exclusive and open to qualifying providers that support OpenJS projects.

• HeroDevs provides security and compatibility support for end-of-life versions of jQuery through its Never Ending Support offering. Learn more about HeroDevs support for jQuery.
• TuxCare provides Endless Lifecycle Support for unsupported jQuery versions, including security fixes for legacy releases and their dependencies. TuxCare joined the OpenJS Ecosystem Sustainability Program in 2026. Learn more about TuxCare support for jQuery.
