jQuery 3.7.1 has been released! This release fixes a regression from jQuery 3.6.0 that resulted in rounded dimensions for <tr /> elements in Chrome and Safari. Also, a (mostly) internal Sizzle method, jQuery.find.tokenize that was on the jQuery object was accidentally removed when we removed Sizzle in jQuery 3.7.0. That method has been restored.

As usual, the release is available on our cdn and the npm package manager. Other third party CDNs will probably have it soon as well, but remember that we don’t control their release schedules and they will need some time. Here are the highlights for jQuery 3.7.1.

jQuery 3.6.0 introduced a change to a support test to account for a sudden failure from Firefox, which started including table borders in computed dimensions for <tr /> elements. That may be actually be correct, but Firefox is the only browser doing it. However, that new support test didn’t account for pages with * { box-sizing: border-box; } in CSS. And so, the support test failed on those pages in all browsers. The result was a fallback to use outerWidth and outerHeight, which unfortunately doesn’t return fractional values. The support test has now been fixed and previous behavior has been restored for Chrome and Safari, but Firefox and IE will continue to return integers.jQuery has inlined most of the code from Sizzle in jQuery 3.7.0 in preparation for larger changes coming to the jQuery selector engine in the future. For the most part, there were no functional changes, but we did accidentally privatize a method that used to be public. While jQuery.find.tokenize was not documented, some code relied on it being available. That method has now been restored.

We do not expect compatibility issues when upgrading from a jQuery 3.0+ version. To upgrade, have a look at the new 3.5 Upgrade Guide. If you haven’t yet upgraded to jQuery 3+, first have a look at the 3.0 Upgrade Guide.

The jQuery Migrate plugin will help you to identify compatibility issues in your code. Please try out this new release and let us know about any issues you experienced.
