After months of testing, the team behind the latest version of the extremely popular Cocos2D game engine for iOS has released version 2.0 of the framework, and it's available for download right now. The framework isn't completely compatible with version 1.0, so devs currently using the previous version on a big project might not want to upgrade in the current build. But the new version is quite fast, includes support for OpenGL ES 2.0, and much simpler code for setting up and maintaining lots and lots of on-screen sprites.

Cocos2D is probably the number one open source engine for iOS game development. It sits inside Apple's Xcode software and allows developers to easily and quickly prototype and develop 2D games and apps. This new version of the software should allow for even easier and more powerful development, leading to even better games and apps for end-users.
