Release Notes
-
general:
- Added Clang/LLVM 19.1.7 toolchain with Arm and RISC-V architecture support.
- GNU toolchain is now based on GCC 14.3 and Binutils 2.43.
- Picolibc is now the default and only C library provided by the SDK.
- Removed newlib and newlib-nano C libraries in the GNU toolchain.
- Dropped NIOS II 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.
- Added Intel ACE40 toolchain (
xtensa-intel_ace40_zephyr-elf).
-
cmake:
- Restructured toolchain CMake script to support GNU and LLVM toolchains.
This requires Zephyr 4.2.0 or above (or the latestcollab-sdk-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.
-
binutils:
- Updated Binutils to 2.43.1 release.
-
gcc:

-mstrict-alignis now set by default when compiling for RISC-V targets.- Added multi-libs for RV32E Zcb targets.
- Added multi-libs for RV64GC Bitmanip targets.
- Added multi-libs for RV64GC large code model targets.
- Added multi-libs for RV64GCV targets.
-
gdb:
- Updated GDB to 16.2 release.
-
qemu:
- Updated QEMU to 10.0.2 release.
