Release Notes
-
general:
- Added Clang/LLVM 19.1.1 toolchain with Arm and RISC-V architecture support.
- Introduced Clang/LLVM toolchain distribution bundle
(zephyr-sdk-VER_HOST_llvm). - Renamed existing "full" GNU toolchain distribution bundle to
zephyr-sdk-VER_HOST_gnu. - Windows executables now link against UCRT, which supports Unicode.
-
cmake:
- Restructured toolchain CMake script to support GNU and LLVM toolchains.
This requires Zephyr 4.1.0 or above (or the latestcollab-sdk-0.18-dev). - Zephyr SDK GNU toolchain now declares
TOOLCHAIN_HAS_GLIBCXX. - Zephyr SDK LLVM toolchain now declares
TOOLCHAIN_HAS_LIBCXX.
- Restructured toolchain CMake script to support GNU and LLVM toolchains.
