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
Symmetric Multi Processing (SMP) support on the Xtensa architecture.
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.

Kernel¶

Initial Symmetric Multi Processing (SMP) support added:
- SMP-aware scheduler
- SMP timer and idling support

- Fixed a few MPU related issues with stack guards
Armv8-M initial architecture support, including the following cores:
- Arm Cortex-M23
- Arm Cortex-M33
New POSIX architecture for native GNU/Linux and macOS build targets:
- Targets native executables that can be run on the host operating system

Boards¶

New native_posix board for the POSIX architecture:
- Includes a template for hardware models
