jQuery 3.4.1 breaks jQuery UI datepicker?

[christopheroussy]

I recently moved to jQuery 3.4.1 which deprecates selectors using :first, :last and such in preparation for jQuery 4.x.

I was wondering how much this impacts jQueryUI datepicker because I grepped into all .js files in my project and in jQueryUI I see: e.dpDiv.find("select.ui-datepicker-year:first").replaceWith(e.yearshtml) and .filter(":first").

Will major jquery libraries like jQuery UI also be updated to remove/replace the deprecated selectors ?

Thanks for the report.

Libraries using jQuery need to adapt to its breaking changes. Because of that, we try to minimize them but from time to time they’re necessary.

Updating jQuery UI to stop relying on positional selectors is a responsibility of jQuery UI. Its bugtracker is https://bugs.jqueryui.com/. Therefore, I’m going to close this issue as this is a jQuery bug tracker.
