Calling 'ev.preventDefault()' on latest Chrome Canary (31.0.1619.0) triggers a warning

[hello@…]

When using 'ev.preventDefault()', a warning shows on Chrome Canary, this happens only once:

event.returnValue is deprecated. Please use the standard event.preventDefault() instead.

JSfiddle: ​http://jsfiddle.net/blaipratdesaba/kN4WQ/

[hello@…]

Been working with other projects, this happens also to previous versions, haven't tested 2.0.x

Looks like the native js method 'event.returnValue' has been marked as deprecated in newer Chrome versions.

This happens also in :

Google Chrome : 31.0.1650.48 (OS X Version)

and Mozilla Firefox 25.0 (OS X Version)

Can confirm this is still happening in Google Chrome : 31.0.1650.48 (OS X Version)

1) Please don't post on duplicate tickets.

2) Please test with the latest version. ​http://code.jquery.com/jquery-git.js

Why didn't you fix this bug yet? It's clearly happening with the latest version of jQuery on any Chrome browser! That's a shame! Please fix ASAP!

jQuery is not what it used to be anymore, lots of bugs wrongly closed or wrongly marked as duplicate... STFU and fix this bug, now.

The bug is fixed in what will become 1.11/2.1. The duplicate bug ticket #14282 explains this. It also explains that older versions of jQuery will give this warning eternally.
