Release Notes
Zephyr project is provided as source code and build scripts for different target architectures and configurations, and not as a binary image. Updated versions of the Zephyr project are released approximately every three-months.
All Zephyr project source code is maintained in a GitHub repository.
For Zephyr versions up to 1.13, you can either download source as a tar.gz file (see the bottom of the GitHub tagged releases page corresponding to each release), or clone the GitHub repository.
With the introduction of the West (Zephyr’s meta-tool) tool after the release of Zephyr 1.13, it is no longer recommended to download or clone the source code manually. Instead we recommend you follow the instructions in Get Zephyr and install Python dependencies to do so with the help of west.
The project’s technical documentation is also tagged to correspond with a specific release and can be found at https://docs.zephyrproject.org/.
