This week's work centers on release and CI infrastructure, board and U-Boot updates, and build framework hardening.

On the release pipeline, asset manifest JSON is now emitted alongside uploads, third-party armbian-images.json sources are merged into the main download index, and dispatch chains were rewired so that build completion fans out cleanly to download-index regeneration and website sync. Ubuntu resolute (26.04) entered the daily build matrix, with corresponding prepare-host adjustments for its qemu-user packaging and a targeted blacklist for boards failing resolute plus GNOME. The new Armbian SDK images are now surfaced on the website and ship preloaded with the build framework, code-server, and developer tooling.

On the platform side, U-Boot v2026.04 lands for Helios4, Rock-5B-Plus, Rock-5T, and NanoPi-M5 (with mainline UFS via a vendor-SPL hybrid), while new bleedingedge branches were introduced for rockchip64 and meson64. Initial support arrived for the Photonicat2 board, new RK3576 SPL and RK3588 DDR blobs were added, Panthor firmware expanded to cover additional Mali GPUs, and a PCIe LTSSM timeout fix improves cold-boot NVMe detection on Rockchip. NanoPC-T6 LTS Plus was renamed, panther-x2 moved from CSC to EOS, and odroidxu4-current advanced to 6.6.138.

In the build framework, an unsafe eval was replaced with declare -g and namerefs, destructive commands were properly quoted, and Docker --privileged is now gated behind an explicit DOCKER_PRIVILEGED toggle. The desktop configuration tree migrated to the armbian-config module_desktops system, kernel build failures now propagate exit codes correctly, missing BOOT_FDT_FILE surfaces as an error alert, and SysRq-via-BREAK was restored on dw-apb-uart for mvebu-6.18 and rockchip64-7.0 kernels.
