SMHUB-OS v1.0.0.beta1

The very first beta of SMHUB OS v1.0.0 — substantial performance updates along with new features at the core of SMHUB.

✨ New Features

• Updated bootloader — mainline OpenSBI 1.8 and U-Boot 2026.04 for better stability and hardware support during boot.
• Fastboot flashing — Type-C flashing now uses fastboot (requires the new smhub-flasher) for much more reliable device recovery.
• Component renaming — the smhub-web package is renamed to smhub-ui to better reflect its role as the primary UI.
• Packaging improvements — a new service helper library for opkg scripts streamlines package management.
• Persistent device identity — EEPROM storage regions for hostname and SSH keys, allowing them to survive a full Type-C flash.
• SD card configuration — a new sdcard config service to configure device parameters via a JSON file on an SD card.
• Dual-core support — communication with the secondary RTOS processor, laying the groundwork for ESPHome on the hub.
• Hardware customization — Linux device tree overlays for dynamic peripheral configuration.
• Hardware RNG — a new kernel driver for the Hardware RNG to improve security and entropy.

⚡ Performance Improvements

• Hardware crypto offload — kernel + OpenSSL support for hardware-accelerated AES and SHA256, improving speeds and lowering CPU usage.
• F2FS for user data — new installs use the Flash-Friendly File System (F2FS) on the user partition, optimized for eMMC (requires a full re-install for existing users).
• Upgraded USB networking — switched the USB networking gadget to CDC-NCM for increased throughput and stability.
• BFG CPU scheduler — migrated the kernel task scheduler to BFG for smoother multitasking and responsiveness.
• Memory compression — enabled zRAM to compress memory pages in RAM, expanding available memory without a swap file that would wear the flash.

🔧 Bug Fixes

• Library paths — fixed ldconfig so custom libraries installed in /opt paths are recognized.
• Smart home stability — disabled smhub-mqtt-bridge by default to resolve conflicts with the primary mosquitto broker.
• MQTT permissions — mosquitto now runs with restricted user privileges instead of root, with fixed logging.
• USB reliability — vendor quirks for the USB PHY driver resolve an interrupt-storm bug, reducing CPU load.
• Time synchronization — added a driftfile to ntpd for long-term clock stability (thanks Ian).
• Package management — restored the python lzma module lost during a Buildroot update.
• App compatibility — patched opkg to respect the Require-OS-Version metadata rule, so packages meant for newer firmware aren't installed by accident.
