Yii 1.1 alpha is released

Dear Yii Folks,

We are proud to announce the alpha release of Yii Framework v1.1!

This release marks a major milestone in the Yii framework development. It includes many new significant features to the already powerful Yii framework. We added a PHPUnit-based testing framework so that developers can more easily write unit tests and functional tests; We added a form builder so that commonly used HTML forms can be built in terms of objects and thus enhance their reusability; We added support for changing skins for widgets globally; We also modified the way of performing relational ActiveRecord queries so that they are more intuitive and easier to use.

For a list of all features included in this release, please visit:



Besides all these core feature enhancements, we also started a new project called zii, which represents a set of official extensions for yii. The zii project will be under heavy development from now on, and we will include it in each of the 1.1 releases.

Do not use this release for production use. This is still an early alpha release, and thus may be subject to changes in future releases without prior notice.

We do not recommend you upgrade from 1.0 to 1.1 if your existing Yii-powered websites already working very well. Upgrading may need quite a bit effort if your project contains a lot of AR models due to the backward-compatibility breaking changes introduced in 1.1.

Good job guys,



Congratullations!!! I love this framework every day more…

Keep the good (and hard) work…

Excellent news. Well done.

Is the "The Definite Guide to Yii" still good? If not, it would be possible to add notes on every example where code should be different?

Yes, the guide is still good. We already added comments and changes when necessary.

great news !! Welcome to 1.1 :)


WOW! Great news!

I think I will test this new version, but just use it for work next year.

  • Thinking how I’ll switch to the new framework :huh:

What about the form builder and this guide http://www.yiiframework.com/doc/guide/form.view ?


This guide page is still fully working and completely valid. Since this release is only alpha, no new features got documented so far in the guide, because they can even be changed.

yeah, form builder is still not documented yet. We also need to document the zii library. We expect them to be ready when we formally release 1.1.

Huhu I love Yii. I love very much with Unit Test.

Thanks the father and mother of Yii for doing it.

congratulations for all team of YII. i happy :P


Yes, enjoy the power of Yii very much, the far I go in my project, the more I love it.

Yii really help me to solve lots of problems in php world !!

Great jobs !! :)

Could we have a small code snippet here on how to use the form builder, so we can test this new feature?

Please see: http://www.yiiframework.com/forum/index.php?/topic/4760-how-to-use-form-builder/

Really cool!!!

What about 1.0 version? Will we still have new releases? I am not going to migrate to 1.1 now, but I would appreciate new fixes at least =)

yes, I think the 1.0.x branch is supported till the end of 2010. (someone correct me if I’m wrong)


Yes, 1.0 will be maintained till the end of 2010. During the time, only bug fixes will be checked into this branch. New features and changes will all go into 1.1 and future 1.2 to maintain strict BC for 1.0.x.
