Yii is an open source project released under the terms of the BSD License. This means that you can use Yii for free to develop either open-source or proprietary Web applications.
The latest stable version of Yii is 1.1. You may safely use this version in your production Web applications. Continued support and bug fixes for this version will be provided until December 31, 2013. If needed, we may further extend our support for this version.
We are currently actively developing our next major version 2.0. Yii 2.0 will be full rebuilt on top of PHP 5.3.0+ and is aimed to become a state-of-the-art of the new generation of PHP framework.
Framework Download
The following releases of Yii are currently available for downloading:
| Yii Framework 1.1.x | Yii Framework 2.0 | |
|---|---|---|
| Latest Release | 1.1.10 (Feb 12, 2012) |
While Yii 1.1 has proven to be a great success, we will not stop here. Our next major release Yii 2.0 will be full rebuilt on top of PHP 5.3.0+, leveraging the new language features as well as the feedback we have received on 1.1. Yii 2.0 will not be compatible with 1.1. However, we will try every effort to make the transition as easy as possible. If you have a new project to develop on Yii, do not wait for 2.0 as it will still take considerable time to reach the production quality. As of April 13, 2012, we have finished base object and component classes with new event system and improved behavior system, logging and error handling, module, model and validators, DAO, query builder, ActiveRecord, console command, view. We still have the following major features to complete before we make an alpha release: caching, i18n, controller, widget, url manager. |
