Application developers, check out the new http://developer.tizen.org (you can also find it in the dropdown at the top left of the new pages). You’ll find lots of information on how to develop apps for Tizen, including Tizen SDK downloads, sample apps, and API documentation. There’s also information on debugging and packaging apps. To ask questions and connect with other developers, check out the forums.
Platform developers should have a look at the new http://source.tizen.org. This is where you can find Tizen source code, the latest snapshots of the code, and Tizen platform documentation.
Finally, you’ll also notice that the second Tizen Developer Conference has been announced! The conference will be held May 22-24, in San Francisco. More details, including registration and CFP, will be available soon.
