Is conditional logic broken / changed in 3.5.5?

I’ve changed the code for the conditional logic script generation to use .on() instead of .live() and it seems to work for me now. The only issue I have is that validation is still performed on fields that have been hidden by conditional logic. I would prefer if a field is hidden by conditional logic that any validation for that field is ignored (i.e., is_required etc).

Here’s the code I’m using at the moment – although I’m hoping there’ll be a fix in the next update – this is around line 796 in acf.php.

// conditional logic
// - isset is needed for the edit field group page where fields are created without many parameters
if (isset($field['conditional_logic']['status']) && $field['conditional_logic']['status']) {

    $join = ' && ';
    if ($field['conditional_logic']['allorany'] == "any") {
        $join = ' || ';
    }

    $if = array();
    foreach ($field['conditional_logic']['rules'] as $rule) {
        $if[] = 'acf.conditional_logic.calculate({ field : "'. $field['key'] .'", toggle : "' . $rule['field'] . '", operator : "' . $rule['operator'] .'", value : "' . $rule['value'] . '"})' ;
    }

    //do script
    echo '<script type="text/javascript">';
    echo '    (function($) {';
    echo '        var conditionalFN = function() {';
    echo '            var field = $(".field-'.$field['key'].'");';
    echo '            if('.implode($join, $if).') {';
    echo '                field.show();';
    echo '            } else {';
    echo '                field.hide();';
    echo '            }';
    echo '        };';
    foreach($field['conditional_logic']['rules'] as $rule ) {
        echo '        $(".field-'.$rule['field'].' *[name]").on("change", function(){';
        echo '            conditionalFN();';
        echo '        });';
    }
    echo '        conditionalFN();';
    echo '    })(jQuery);';
    echo '</script>';
