Tizen OS 5.5 Second Preview Released


The second trial version of the Tizen 5.5 mobile platform has been released, version that is aimed at introducing developers to the new features of the platform. Tizen OS is a project being developed under the auspices of the Linux Foundation, most recently with Samsung. Tizen is built on Samsung's Linux platform (Samsung Linux Platform - SLP), a reference implementation built into LiMo.

The project was originally conceived as an HTML5-based platform for mobile devices to be successful in MeeGo. Samsung merged its previous Linux-based operating system effort, Bada, into Tize, and has since used it primarily on platforms such as handheld devices and smart TVs.

The platform continues the development of MeeGo and LiMO projects and is distinguished by the ability to use web APIs and web technologies (HTML5, JavaScript, CSS) to create mobile applications. The graphical environment is based on the Wayland protocol and in the project experience Enlightenment and Systemd it is used to administer services.

The code is licensed under GPLv2, Apache 2.0, and BSD. Whereas Tizen OS builds are made for Raspberry Pi 3, ODROID U3, ODROID x U3, Artik 710/530/533 and various arm64 based mobile platforms and armv7l architectures.
