This is the first public beta release of Arm Mbed OS and associated tools. It focuses on laying the foundation for Mbed OS development and collaboration, particularly core tools, technology and testing. 

We expect Mbed OS developers to be able to clone, build and run example projects and to inspect the underlying code.

If you’re already using mbed, please note that Mbed OS is a new operating system; although it shares part of the code with Mbed Classic, it has its own structure, tools, APIs and philosophy. We recommend reading the links below in order to understand how Mbed OS is different from Mbed Classic and what you need to do to take full advantage of Mbed OS.

To get started with Mbed OS, please visit our Getting Started guides. You’ll learn about the tools you need to install in order to use Mbed OS, as well as what you need to do in order to build and run your first Mbed OS program.

To find out more about how Mbed OS is structured and the services currently available in Mbed OS, please visit the Mbed OS repository on GitHub. It contains a list of the code repositories used in Mbed OS, a list of the currently supported targets and other useful information.

Note that this is a beta release - this means that the software is still maturing, and many things will change. In particular, module names, repo URLs, APIs, header file names, configuration parameters and any other detail can and will change. We'll try to mitigate the imposition that these changes have on your code where possible, but please expect backwards-incompatible changes.
