Apr 1, 2025April 2025 — zephyrproject-rtos/poky: Delivered a maintenance-feature update to Binutils 2.42, adding Z17 CPU name support for the s390 architecture. The change (commit 679db8c1a328f534955fde7b575d77b237234ff7) enhances toolchain compatibility and downstream packaging for customers updating to newer zSeries configurations. Validated with targeted tests and builds; no regressions observed. Business value: improved toolchain reliability for s390 workflows and smoother upgrade paths for downstream projects. No major bugs fixed this month; primary focus was feature delivery, validation, and maintaining long-term stability of the Poky binutils package.
