| Zephyr Kernel 1.6.0 Release Notes |
| ################################# |
| |
| We are pleased to announce the release of Zephyr kernel version 1.6.0. This |
| release introduces a the unified Kernel replacing the separate nano- and |
| micro-kernels and simplifying the overall Zephyr architecture and programming |
| interfaces. |
| Support for the ARM Cortex-M0/M0+ family was added and board support for |
| Cortex-M was expanded. |
| Additionally, this release adds many improvements for documentation, build |
| infrastructure, and testing. |
