Second edition of the Yii Application Development Cookbook by Alexander Makarov will be available in a few weeks. In the new version many recipes were updated and rewritten to reflect latest Yii and PHP world changes and improve overall experience. Additionally all errata from the first edition was fixed.

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.
