Tizen 2.0, the open-source smartphone operating system, is now available as an alpha release with an accompanying Software Development Kit (SDK), the Tizen project announced on Tuesday. The release lends credence to rumors that project member Samsung Electronics is planning to launch a version of its Galaxy S3 smartphone running Tizen instead of Google's Android.
The release is aimed at developers who can start working with new features and provide feedback in "the final stages" of Tizen's development, the Tizen Technical Steering Group announced on its blog.

Tizen is a Linux-based open-source operating system and software platform backed by Samsung, Intel and other vendors. The software is intended for use in devices such as smartphones, tablets, netbooks, in-vehicle infotainment devices, and smart TVs.
The latest code release shows that Tizen is getting closer to a usable product, and comes two weeks after the Wi-Fi Alliance published a document certifying that a Samsung smartphone named the "GT-I9300_TIZEN" had passed Wi-Fi interoperability testing, according to a copy of the document in Google's cache. GT-i9300 is the model name Samsung gives to Galaxy S3 smartphones, all of which currently run Android, indicating that Samsung might be working on a Galaxy S3 variant that runs Tizen.
Samsung did not immediately comment on its plans for Tizen, and the Wi-Fi Alliance certificate has been modified since its initial publication, now listing the smartphone as the GT-I9300Z).
The Tizen 2.0 alpha release provides developers with the Tizen kernel, device drivers, middleware subsystems, and Web APIs, necessary to develop future Tizen-compliant software, according to the source code release page.
The latest release for instance adds advanced HTML5 features such as video subtitles and captions and a battery status application programming interface, the steering group wrote. A multi-process Webkit2-based Web Runtime was also added to provide better security and reliability for Web applications, the team announced among other improvements.
The steering group is planning to add additional components in the coming weeks and is planning to make additional enhancements to the Tizen OS "over the coming months" based on feedback from developers. The alpha 2.0 source code release follows a preview release of the OS source code last January.
