Two channels: the 3.0.0 development preview (the L0/L1 world of WP06c) and the 2.2.0 stable release. Every asset's SHA256 is listed - verify what you download: sha256sum <file>.
3.0.0-WP06c - development preview
The current 3.0.0 milestone: OCBL → OCOS → the ring-3 ush shell (285 commands), plus the OCSE install environment (the 9-step GUI install wizard + OCSECL, en/zh). Boot either ISO in QEMU (-cdrom) or write it to USB. See the WP-06c release page.
opencube-3.0.0-WP06c.iso
Hybrid BIOS + UEFI image (3.5 MiB). Boots through OCBL into the ring-3 ush shell - the development preview of 3.0.0.
ocse-3.0.0-WP06c.iso
The OCSE install environment (4.2 MiB): the 9-step GUI install wizard and OCSECL, en/zh - every wizard mutation is a real OCSECL command. Installs OCBL + OCOS onto a disk that then boots to ush.
Try it in one command
512 MiB of RAM is comfortable; the ISO is self-contained. The installed-disk path: boot ocse, run the wizard, reboot - OCBL takes over.
2.2.0 - the stable release -
The last formal release of the 2.x line · build - · -. The 2.x world (recovery shell included) - kept for reference and real-hardware stability.
-
Hybrid BIOS + UEFI image (~12 MiB). Boot it in QEMU (-cdrom) or write it to a USB stick for real hardware.
-
Deterministic source zip (git archive): tree order, commit mtimes, index permissions - the same commit always rebuilds the same zip.
-
Update package for a running system: checkupdate fetches the manifest, verification is SHA256 + signature, install goes to the inactive A/B slot.
