v0.0.82

What's New

Secure Boot Support

• Bundled Microsoft-signed shim bootloader (bootimus-shimx64.efi, bootimus-shimaa64.efi) from iPXE v2.0.0 for UEFI Secure Boot environments.
• No custom signing required — uses iPXE's official Secure Boot CA chain.

USB Boot Images

• Built-in USB boot images embedded in the binary for machines without PXE support.
• Downloadable directly from the admin UI under Settings > USB Boot Images.
• Standard BIOS/UEFI and Secure Boot variants included.
• Write to USB with dd and boot — iPXE uses DHCP to find bootimus automatically.

ISO Organisation

• Folder-based groups: Drop ISOs into subdirectories and they automatically become groups/submenus in the boot menu. Nested folders create nested submenus.
• Groups can also be managed manually via the admin UI.

Admin UI

• Settings tab: Configure the boot menu title displayed to PXE clients.
• USB Boot Images section: Download bootable USB images directly from the admin panel.

Client Management

• Per-client menus: Clients with assigned images now see only those images. Unregistered clients or clients with no assignments see all public images.

ISO Compatibility

• TrueNAS SCALE: Kernel extraction now supported (root-level vmlinuz/initrd.img layout).
• Proxmox VE: Kernel extraction now supported (boot/linux26 layout).
• Manual extraction: Place vmlinuz and initrd in data/isos/<iso-name>/ and bootimus detects them automatically on next scan.
• Spaces in filenames: ISOs with spaces in their names are now properly URL-encoded in boot menus.

Docker / Build

• Makefile refactor: Clean targets — make build, make run, make docker-build, make docker-up, make docker-push, make release, make binaries.
• Unified buildx pipeline: make binaries builds all platform binaries via docker buildx in one pass.
• Configurable platforms: make docker-push PLATFORMS=linux/amd64 to skip slow arm64 cross-compilation.
• Dockerfile fix: Fixed Debian Trixie compatibility — wimtools dependencies (libicu, libxml2) installed via apt-get instead of fragile manual .so copying. Fixes issues on Synology and other platforms. Thanks to @TheWorstTech for reporting.
• Single Dockerfile: Consolidated into a single multi-stage Dockerfile.
• iPXE pinned to v2.0.0: Bootloader builds pinned to known-good iPXE commit to avoid upstream regressions.

Bug Fixes

• Fixed ImageGroup unique index to allow same folder name under different parents.
• Fixed client menu not filtering to assigned images only.
