Zephyr Project <taldrich@...>

Welcome to the Zephyr Project Newsletter! As the Zephyr community continues to grow and innovate we've added this update to the list of resources and tools available to our ecosystem to stay connected. In this edition, we are excited to bring you updates on what's in store for ZephyrOS this summer and fall, provide a glimpse into some of the work currently underway in the community and share ways you can get involved in the Zephyr Project. 


About the Zephyr Project

Zephyr Project Welcomes it's 500th Contributor!

Community is core to a successful open source project. In addition to improving and expanding the code base, a vibrant and diverse community brings new perspectives, energy and opportunity. Over the last year the Zephyr community has grown dramatically and the project is stronger because of these new voices. This month, the Zephyr Project is thrilled to welcome it's 500th contributor. On behalf of the entire community, we would like to welcome each and every one of the new contributors. 

If you are interested in joining the Zephyr Project as a member or contributor please reach out. We are here to help.

The Zephyr Project Announces Major Technical Milestone with Release of Zephyr OS 1.14 LTS. 

Earlier this spring, Zephyr Project introduced the first long term support (LTS) release of Zephyr OS, Zephyr 1.14.0 LTS. This release is an important technical milestone for the community and is intended to be a more stable, certifiable option for product makers and developers. Major enhancements include:
  • Support for over 160 different board configurations spanning 8 architecture configurations. 
  • Enhancement of the native POSIX port by adding UART, USB, and display drivers. Based on this port, we added a simulated NRF52832 SoC which enables running full system, multi-node simulations, without the need of real hardware.
  • Application of MISRA-C code guideline on the kernel and core components of Zephyr. 
  • Addition of an experimental BLE split software Controller with Upper Link Layer and Lower Link Layer for supporting multiple BLE radio hardware architectures.
  • Introduction of the west tool for management of multiple repositories and enhanced support for flashing and debugging.
  • Support for the x86_64 architecture. It is currently implemented only for QEMU targets, supports arbitrary numbers of CPUs, and runs in SMP mode by default, our first platform to do so.
  • Added support for application user mode, application memory partitions, and hardware stack protection in ARMv8m
This release marks the culmination of one of the largest and most ambitious efforts undertaken by the Zephyr Project to date. This release would not have been possible without the hard work and skill of the 250 developers who contributed code over the last 6 months. Read more here.
