| Zephyr Kernel 1.6.0 |
| #################### |
| |
| We are pleased to announce the release of Zephyr kernel version 1.6.0. This |
| release introduces 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. |
| |
| Major enhancements included with the release: |
| |
| * Introduced the Unified Kernel; the nano and micro kernel were removed. |
| * The legacy API is still supported but deprecated. |
| * Legacy tests and samples were moved to tests/legacy and samples/legacy. |
| * Unified kernel documentation was added and legacy nanokernel/microkernel |
| documentation was removed. |
| * Added support for several ARM Cortex-M boards |
| * Added support for USB mass storage and access to the filesystem. |
| * Added native Bluetooth Controller support. Currently nRF51 & nRF52 are supported. |
| |
