Zephyr Kernel 1.11.0
#####################

We are pleased to announce the release of Zephyr kernel version 1.11.0.

Major enhancements with this release include:

* Thread-level memory protection on x86, ARC and Arm, userspace and memory
  domains

* Initial Armv8-M architecture support.
* Native development environment on Microsoft Windows.
* Native build target on POSIX platforms.
* POSIX PSE52 partial support.
* Thread support via integration with OpenThread.
* Firmware over-the-air (FOTA) updates over BLE using MCUmgr.
* Lightweight flash storage layer for constrained devices.
* Additional SoC, platform and driver support for many of the already supported
  platforms.

The following sections provide detailed lists of changes by component.
