We are very pleased to announce that Yii Framework version 1.1.20 is released. You can download it at yiiframework.com/download/.
This release is a maintenance release of Yii 1.1 which has reached maintenance mode and will only receive necessary security fixes and fixes to adjust the code for compatibility with PHP 7 if they do not cause breaking changes. This allows you to keep your servers PHP version up to date on the environments where old Yii 1.1 applications are hosted to stay in the version ranges supported by the PHP team. Yii 1.1.20 is compatible with PHP 7.2, which at the time of this writing has a announced security issue support until November 30, 2020.
We recommend to use Yii 2.0 for new projects and also to introduce Yii 2.0 for developing new features in existing Yii 1.1 apps, as described in the Yii 2 guide.
Upgrading a whole app to Yii 2.0 will result in a rewrite in most cases so this option provides a way for upgrading step by step and allows you to keep old applications up to date even with low budget.
This release includes a few PHP 7 compatibility fixes and security improvements.
