What's new in jQuery 1.4?

Question

What's new in jQuery (including the user interface) and I am having problems (using the user interface and datepicker) when switching to 1.4 (and 1.8.2)?

Answer 1

There are some violations of change . The most important thing is that all the plugins that you use are already updated to support 1.4 and use only updated versions. Then you should not have any problems or only minor problems that you can ultimately easily solve. But the benefits (such as performance) are worth it.

Answer 2

I liked the most:

jQuery('<div/>', {
    id: 'foo',
    css: {
        fontWeight: 700,
        color: 'green'
    },
    click: function(){
        alert('Foo has been clicked!');
    }
});

You have a good collection here .
