We are pleased to announce the release of Zephyr kernel version 1.7.0. This
release continues refinement of the unified kernel introduced with the 1.6.0
kernel release, simplifying the overall Zephyr architecture and programming
interfaces. This is the last release that will support the deprecated legacy
nano- and micro-kernel APIs found in the 1.5.0 release and earlier.
This release introduces a new native IP stack, replacing the legacy uIP stack,
maintaining the legacy functionality, adding additional capabilities, and allowing
We have introduced support for the RISC V and Xtensa architectures and now
support 6 architectures in total.
Device tree support for ARM based boards added. The initial
device tree support includes flash/sram base address and UART devices. Board
support includes NXP Kinetis based SoCs, ARM Beetle, TI CC3200 LaunchXL, and
STML32L476 based SoCs. Plan is to add support for other architectures and
expand device support in upcoming Zephyr releases.

Many thanks to all who contributed to this release and continue to make Zephyr
better every day.
Master branch is now open for feature development. The Zephyr 1.8 release is
planned for end of May 2017.
