In addition, it includes several security and performance improvements in commonly used services, such as <code>$compile</code>, <code>$injector</code>, <code>$parse</code>, <code>$animate</code>, and directives, such as <code>input</code>, <code>ngModel</code> and <code>select</code>.</p> <p>The most notable changes are:</p> <ul> <li>Aligning jqLite with the latest version of jQuery (3.x).</li> <li>Implementing long awaited features, such as support for inputs of type <code>range</code> and the ability to bind to any type of values using <code>ngRepeat</code> with <code>select</code>.</li> <li>Disabling (by default) the pre-assignment of bindings on controller instances, which helps with support for native ES6 classes.</li> <li>Changing the default <code>$location</code> hash-prefix to <code>&#39;!&#39;</code>, as the previous empty string default was unconventional and confusing.</li> <li>Reporting possibly unhandled promise rejections that would otherwise go unnoticed.</li> </ul> <p>Another major change is the removal of the <strong>Expression Sandbox</strong>. This should not require changes to your application (and may give it a small performance boost), but we strongly recommend reading the <a href="http://angularjs.blogspot.com/2016/09/angular-16-expression-sandbox-removal.html">Sandbox Removal Blog Post</a> to understand the implications behind the removal and whether any action is required on your part.</p> <p><br /> You may also notice that this release comes with a longer-than-usual list of breaking changes. Don&#39;t let this dishearten you though, since most of them are pretty minor - often not expected to affect real applications. These breaking changes were necessary in order to:</p> <ul> <li>Align with breaking changes in jQuery 3.</li> <li>Fix bugs that we wouldn&#39;t be able to fix otherwise.</li> <li>Introduce new features, performance improvements and security fixes.</li> <li>Make the behavior of existing features more consistent and predictable.</li> </ul> <p><br /> To give you a heads-up, here is a brief summary of the breaking changes that are expected to have the highest impact. Make sure you look them up in the full list below or check out the corresponding commits for more info.</p> <ul> <li><p><strong>$location</strong> now uses <code>&#39;!&#39;</code> as the default hash-prefix for hash-bang URLs, instead of the empty string. (<a href="guide/migration#commit-aa077e8">Details</a>)</p> </li> <li><p><strong>$compile</strong> will (by default) not pre-assign bindings on component/directive controller instances. (<a href="guide/migration#commit-bcd0d4">Details</a>)</p> </li> <li><p><strong>http</strong> imposes additional restrictions to <strong>JSONP</strong> requests for security reasons (see <a href="guide/migration#migrate1.5to1.6-ng-services-$http">details</a> below):</p> <ul> <li>The request URL now needs to be trusted as a resource URL.</li> <li>You can no longer use the <code>JSON_CALLBACK</code> placeholder for specifying the query parameter for the callback.</li> </ul> </li> </ul> <ul> <li><strong>jqLite</strong> is more aligned to jQuery 3, which required the following changes (see <a href="guide/migration#migrate1.5to1.6-ng-misc-jqLite">details</a> below):<ul> <li>Keys passed to <code>.data()</code> and <code>.css()</code> are now camelCased in the same way as the jQuery methods do.</li> <li>Getting/setting boolean attributes no longer takes the corresponding properties into account.</li> <li>Setting boolean attributes to empty string no longer removes the attribute.</li> <li>Calling <code>.val()</code> on a multiple select will always return an array, even if no option is selected.</li> </ul> </li> </ul> <ul> <li><p><strong>input[type=radio]</strong> now uses strict comparison (<code>===</code>) to determine its &quot;checked&quot; status. (<a href="guide/migration#commit-5ac7da">Details</a>)</p> </li> <li><p>The improved support for <strong>input[type=range]</strong> means that the behaviour of range inputs (when bound to <code>ngModel</code>) has changed. (<a href="guide/migration#commit-913016">Details</a>)</p> </li> <li><p><strong>ngTransclude</strong> now treats whitespace-only transclusion content as empty and uses the fallback content instead. (<a href="guide/migration#commit-32aa7e">Details</a>)</p> </li> <li><p><strong>ngAria/ngModel</strong> no longer overrides the default <code>$inEmpty()</code> method for custom <code>checkbox</code>-shaped controls. (<a href="guide/migration#commit-975a61">Details</a>)</p> </li> </ul> <p><br /> Below is the full list of breaking changes:</p> <ul> <li>Core:<ul> <li><a href="guide/migration#migrate1.5to1.6-ng-directives">Directives</a><ul> <li><a href="guide/migration#migrate1.5to1.6-ng-directives-form">form</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-directives-input[number]">input[number]</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-directives-input[radio]">input[radio]</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-directives-input[range]">input[range]</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-directives-ngBind">ngBind</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-directives-ngModel">ngModel</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-directives-ngModelOptions">ngModelOptions</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-directives-ngTransclude">ngTransclude</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-directives-select">select</a></li> </ul> </li> <li><a href="guide/migration#migrate1.5to1.6-ng-services">Services</a><ul> <li><a href="guide/migration#migrate1.5to1.6-ng-services-$compile">$compile</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-services-$http">$http</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-services-$interpolate">$interpolate</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-services-$location">$location</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-services-$q">$q</a></li> </ul> </li> <li><a href="guide/migration#migrate1.5to1.6-ng-misc">Miscellaneous</a><ul> <li><a href="guide/migration#migrate1.5to1.6-ng-misc-jqLite">jqLite</a></li> <li><a href="guide/migration#migrate1.5to1.6-ng-misc-decorator">decorator()</a></li> </ul> </li> </ul> </li> <li>Modules:<ul
