We are very pleased to announce the release of Yii Framework version 2.0.44.
Please refer to the instructions at https://www.yiiframework.com/download/
to install or upgrade to this version. This release includes a number of bug fixes as well as security enhancements and feature enhancements. Highlights are:

• Added ability to turn the sorting off for a clicked column in GridView with multisort.
• Added yii\helpers\Json::$keepObjectType and yii\web\JsonResponseFormatter::$keepObjectType in order to avoid changing zero-indexed objects to array in yii\helpers\Json::encode().
• Added support for URI namespaced tags in XmlResponseFormatter.
• Added yiiActiveForm validate_only property for skipping form auto-submission.
• Added yii\base\Module::setControllerPath().
• Added yii\helper\BaseHtml::$normalizeClassAttribute. When enabled, it will remove duplicate classes from tags generated.
• Added XmlResponseFormatter::$objectTagToLowercase option to lowercase object tags.
• Reduced memory usage in yii\base\View::afterRender method and other performance enhancements including events handling.
