SimpleLink Zephyr Demo 2 Release Notes

Texas Instruments Zephyr GitHub repository is the downstream fork
Zephyr and is the starting point
for developers wanting to start developing Zephyr applications.

The SimpleLink™ downstream Zephyr releases are intended as an additional demo
platform and eventually where the production grade TI SimpleLink™ Zephyr SDKs
will be hosted. The team is also working on upstreaming this content to
mainline Zephyr.
