    Force Resource Conversion

    Through asset bundle, you can convert resources automatically. For example, LESS in CSS. However, keeping track of all changes in the source files is quite expensive. Especially when you import one resource into another. In such cases, you can forcefully convert resources. For this, the component is assetManagerconfigured as follows:

        'components' =>  [
            'assetManager' => [
                'converter' => [
                    'forceConvert' => true,

    Subquery Selection

    The query builder supports subqueries in many places. Now and in SELECT:

    $subQuery = (new Query)->select('COUNT(*)')->from('user');
    $query = (new Query)->select(['id', 'count' => $subQuery])->from('post');
    // $query represents the following SQL:
    // SELECT `id`, (SELECT COUNT(*) FROM `user`) AS `count` FROM `post`

    Prevent CSS reloading with AJAX requests

    Yii already had tools to prevent JavaScript from reloading on AJAX requests. Now there is also for CSS. To use this feature, registration is required YiiAssetas shown below:


    Clearing the database schema cache

    We added a new command to clear the database schema cache. It will be useful for laying out code on production servers. The command runs as follows:

    yii cache/flush-schema

    Helper enhancements

    The method Html::cssFile()now supports an option noscriptdesigned to wrap the generated tag linkin a tag noscript. This option can also be used during configuration AssetBundle::cssOptions. For example:

    use yii\helpers\Html;
    echo Html::cssFile('/css/jquery.fileupload-noscript.css', ['noscript' => true]);

    Previously StringHelper::truncate()supported trimming a simple string to a given number of characters or words. HTML is now also supported, which remains fully valid when cropping.

    The class has Inflectoracquired a new method sentence()that collects an array of words into a sentence. For instance:

    use yii\helpers\Inflector;
    $words = ['Spain', 'France'];
    echo Inflector::sentence($words);
    // output: Spain and France
    $words = ['Spain', 'France', 'Italy'];
    echo Inflector::sentence($words);
    // output: Spain, France and Italy
    $words = ['Spain', 'France', 'Italy'];
    echo Inflector::sentence($words, ' & ');
    // output: Spain, France & Italy

    Bootstrap Extension Enhancements

    Bootstrap CSS framework updated to version 3.3.x. If you want to use the old version, you can specify it explicitly in the composer.jsonproject.

    MongoDB Support Enhancements

    Operation is findAndModifynow supported both as yii\mongodb\Querywell as yii\mongodb\ActiveQuery. For example:

    User::find()->where(['status' => 'new'])->modify(['status' => 'processing']);

    Requests to MongoDB are now displayed on the debug panel. To use it, you should configure the debugger as follows:

        'class' => 'yii\debug\Module',
        'panels' => [
            'mongodb' => [
                'class' => 'yii\mongodb\debug\MongoDbPanel',

    Redis Extension Enhancements

    The Redis extension now supports UNIX sockets, which is often 50% faster than TCP. The connection is configured as follows:
