We are very pleased to announce the release of Yii Framework version 2.0.21. Please refer to the instructions at https://www.yiiframework.com/download/ to install or upgrade to this version.

Version 2.0.21 is a minor release of Yii 2.0 which fixes some bugs, improves database connection performance and adding support for sameSite cookie option for regular and session cookies.

Info: yii\db\Query::select() and addSelect() now normalize the columns when saving them to $this->select, so code that works directly with that property directly may need to be modified.

Thanks to all Yii community members who contribute to the framework, translators who keep documentation translations up to date and community members who answer questions at forums.

There are many active Yii communities so if you need help or want to share your experience, feel free to join them.

A complete list of changes can be found in the CHANGELOG.
