Hi all,

We’ve release the first release candidate for the SDK 0.13.0. The main changes in these release are support for ARC64, Qemu 6.0.0, OpenOCD, and some newlib updates/fixes.

SDK 0.13.0-rc1 can be found here:

https://github.com/zephyrproject-rtos/sdk-ng/releases/tag/v0.13.0-rc1

Please download and try things out and report any issues.

Changes since the last release:

• general:
- Added support for ARC64. NOTE: GDB isn't currently supported for ARC64.

• qemu:
- Updated to QEMU 6.0.0
- Added arc64 support. NOTE: this update ARC support replaces the machine (-M simhs) with (-M virt). This change will require updates to boards/arc/qemu_arc/board.cmake in Zephyr to match.
- Pull in fixes from upstream for:
hw/arm: Fix modelling of SSE-300 TCMs and SRAM

• gcc:
- Update to gcc 10.3 release
- Added support for ARC64
- Removed libgcc transactional memory clone registry support
- Fixed incorrect build specs for libstdc++ nano variant. The libstdc++ nano variant, which is used with newlib-nano, is now built with -fno-exceptions to reduce compiled binary size.

• binutils:
- Updated to add support for ARC64

• newlib:
- Updated to add support for ARC64
- Added multithreading support

• openocd:
- Update to upstream 20210630 snapshot

• crosstool-ng:
- sync with upstream. Upstream now supports newlib-nano so we drop our Zephyr specific updates. This also pulls in gcc-10.3 and initial support for ARC64.

• yocto:
- Update to yocto 3.2.3 baseline. This is in prep to support building qemu-6.0.0
