Yii 2.0 is finally coming, after more than three years of intensive development with almost 10,000 commits by over 300 authors! Thank you for your support and patience!

As you may have already known, Yii 2.0 is a complete rewrite over the previous version 1.1. We made this choice in order to build a state-of-the-art PHP framework by keeping the original simplicity and extensibility of Yii while adopting the latest technologies and features to make it even better. And today we are very glad to announce that we have achieved our goal.

Below are some useful links about Yii and Yii 2.0:

We are very pleased to announce the release of Yii 2.0 RC (Release Candidate). You may follow the instructions on yiiframework.com to install or upgrade to this version.

This RC release includes about 100 bug fixes and 200 new features and enhancements. It is a result of five months of intensive development since the prior Beta release. During this period, we have received a lot of help from the Yii community users. We hereby thank everyone who has contributed to Yii and made this release possible. You are the best!

Commonly Asked Questions ¶

We are releasing Yii 1.1.15 to fix a security issue found in 1.1.14. We urge all 1.1.14 users to upgrade their Yii to this latest release. Note that the issue only affects 1.1.14. All previous releases are not affected. Upgrading to this release from 1.1.14 is very safe and will not break your existing code.

The vulnerability is in the CDetailView widget. When a Yii application uses this widget and configures the "value" property of a CDetailView attribute using end user inputs, it may allow attackers to potentially execute arbitrary PHP scripts on the server. We are not showing how to exploit it here to allow users to upgrade before details about the exploit become publicly known. To our knowledge the details of this issue are only known to core team members.

We have reserved for this issue a CVE number (CVE-2014-4672) which you can use to refer to it.

We are very pleased to announce the Beta release of Yii Framework version 2. You can download it from yiiframework.com.

This Beta release includes hundreds of new features, changes and bug fixes that have been made since the alpha release. We will review the most important ones in the following. But first, we would like to answer some commonly asked questions regarding Beta.

Commonly Asked Questions ¶

We are very pleased to announce the alpha release of Yii Framework version 2. You can download it from yiiframework.com.

Yii 2 is a complete rewrite of Yii - one of the most popular PHP frameworks. Yii 2 inherits the main spirit behind Yii for being a simple, fast and highly extensible PHP framework. Yii 2 exploits the latest language features available in PHP 5.4 and embraces the best practices found in modern Web application development. For a complete description of the features offered by Yii 2, please check out The Definitive Guide and The Guide of Upgrading from Yii 1.1.

The alpha release of Yii 2 marks a major milestone in the course of Yii 2 development. It means that the code base of Yii 2 has reached a certain degree of stability. If you just start to learn Yii or you do not have a tight project schedule, you may consider using Yii 2. Please do not use Yii 2 in production as we may still introduce significant changes without prior notices.

Over the past two years, we have received tremendous contributions to Yii 2 from our community. We hereby thank every contributor for making this release possible.

We are very pleased to announce that Yii Framework version 1.1.14 is released. You can download it at yiiframework.com/download/.

In this release, we fixed more than 80 bugs and introduced more than 60 minor enhancements and features. We added CPasswordHelper that provides secure and up to date way to store and verify password hashes; We added CRedisCache to support using Redis for caching purpose; and Yii can now be installed as a Composer package. For the complete list of changes in this release, please see the change log.

We have received significant contributions to this release from our community users (e.g. creocoder, tom--, paystey, Ragazzo, antoncpu, Yiivgeny) to this release. We hereby thank their effort in making this release available.

It was recently announced that the Yii website was defaced, but until recently we were still investigating. Here are some details about what happened and what was affected:

1. The website's index.php was compromised through a vulnerability in the separate forum software (IPB, not Yii).
2. Neither the website's code nor Yii framework code was involved or part of the attack in any way. Hence, the security of the Yii framework remains as secure today as it was yesterday.
3. No framework downloads were affected, as the Yii framework source code is hosted externally.

Although we're storing passwords encrypted and are salting hashes, we may request you to change your forum account password soon.

Earlier today it was discovered that the entry page on the Yii website had been defaced. The website was restored in less than an hour from discovery of this event, and we are currently investigating the cause of it.

At this point we do not expect any of the Yii framework source code to have been affected, as the source code for the framework is hosted on external systems (GitHub and Google Code) which to our knowledge has not been affected.

As an extra precaution we do however recommend that if you downloaded a copy of the framework via the main website (www.yiiframework.com) earlier today, you delete that copy and download it again. The purpose of this is to be certain that the copy is really downloaded from Google Code and/or GitHub, even though there are no signs of downloads or source code having been affected by the defacement.

We will continue our investigation and take appropriate action once we have more information.

We are very pleased to announce the release candidate of Yii Framework version 1.1.14. You can download it at GitHub.

We are very pleased to announce that Yii 2 is now available for public preview at GitHub. This is a major milestone during the Yii 2 development which was started more than two years ago and has since undergone complete rewrite.

Note that Yii 2 is still under heavy development. We may introduce significant changes without prior notices. So please do not use it for production.

We sincerely invite you to review and play around the code, and give us feedback. We also welcome you to participate in developing Yii 2.

You may keep an eye on the following Yii 2 resources:

Second edition of the Yii Application Development Cookbook by Alexander Makarov will be available in a few weeks.

It features some brand new recipes:

• Rendering content at the client side
• Leveraging HTTP caching
• Using Composer with Yii

You can learn much more about the book on its companion website. Feel free to discuss it at the forums.

Yii plugin adds useful enhancements to NetBeans IDE including the following:

• Go To Action, Go To View.
• Go to view via clicking on render or renderPartial argument.

This is a April Fool news

We are very pleased to announce our decision on Yii2 development. Starting April 1st, 2013, the existing Yii2 code will be rewritten using Ruby programming language. Current PHP code will be left as is. After months of consideration, we have decided that Ruby compliments Yii2 better than PHP does.

We will do our best to make transition as easy as possible; you do not need to worry about potential migration problems.

Cheers! The Yii Developer Team

You probably heard about a good WYSIWYG editor called Imperavi Redactor or even tried it. If you like it, there's a good news for you. Our excellent community funded buying Redactor OEM license so now it can be used for free for any Yii-based product.

Since we do not want to bloat Yii itself too much, it will not be integrated into the core framework. You can get it as an extension from YiiExt repository.

Note that Redactor itself isn't OpenSource product so check if license is OK for you before actually using it.

We just have two new Yii books published: "Web Application Development with Yii and PHP", and "The Yii Book".

The book "Web Application Development with Yii and PHP" is actually an updated edition of "Agile Web Application Development with Yii 1.1 and PHP5" which was the first Yii book published back in 2010. Written by Jeffrey Winesett, this book introduces Yii by applying it to build a real world project management system. Find more information about this book

"The Yii Book" is written by Larry Ullman, a professional writer of many best-selling books. This book tries to explain the most important features and concepts in the Yii framework, using practical, real-world examples. Find more information about this book

Since the last release (Yii 1.1.12), we have accumulated 31 bug fixes, 39 enhancements and 6 updates. It's time for us to prepare for the next release: Yii 1.1.13.

As it happened few times in the past that bugs where discovered immediately after a new release we decided to start with a new release practice that hopefully will give much better and stable releases.

On Dec 2, 2012. we will make a Yii 1.1.13 RC (Release Candidate)!
