The shrinking is only for faster image downloads. After flashing, the image should auto-expand to fill the SD card. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

## Stegasoo v4.1.5
|
|
|
|
### Developer Experience
|
|
- **Educational Code Comments**: Core modules now include detailed explanations
|
|
- DCT: zig-zag coefficient diagrams, QIM embedding math, Reed-Solomon "Voyager" reference
|
|
- LSB: visual bit manipulation examples, ChaCha20 pixel selection
|
|
- Crypto: multi-factor KDF flow diagrams, Argon2id memory-hardness reasoning
|
|
- CLI/Web: architectural patterns for future contributors
|
|
|
|
### Raspberry Pi Improvements
|
|
- **Streamlined Image Creation**: `pull-image.sh` now handles everything
|
|
- Auto-resizes rootfs to exactly 16GB (for smaller download)
|
|
- Preserves auto-expand (image fills SD card on first boot)
|
|
- Compresses with zstd
|
|
- Optional .zst.zip wrapper for GitHub releases
|
|
- **16GB Minimum**: Pre-built images are now 16GB (was variable)
|
|
- **Host Requirements**: `rpi/host-requirements.txt` documents all dependencies
|
|
- **Test Automation**: `kickoff-pi-test.sh` for one-command flash+test cycles
|
|
|
|
### MOTD Polish
|
|
- Dynamic temperature emoji (ice/cool/fire based on CPU temp)
|
|
- Rocket emoji for service status
|
|
- Cleaner formatting
|
|
|
|
### Raspberry Pi Image
|
|
Download `stegasoo-rpi-4.1.5.img.zst.zip` from Releases.
|
|
|
|
```bash
|
|
# Flash (auto-detects SD card)
|
|
sudo ./rpi/flash-image.sh stegasoo-rpi-4.1.5.img.zst.zip
|
|
|
|
# Or manual
|
|
zstdcat stegasoo-rpi-4.1.5.img.zst | sudo dd of=/dev/sdX bs=4M status=progress
|
|
```
|
|
|
|
Default login: `admin` / `stegasoo`
|
|
|
|
First boot runs the setup wizard for WiFi, HTTPS, and channel key configuration.
|
|
|
|
### Docker
|
|
```bash
|
|
docker-compose up -d web # Web UI on :5000
|
|
docker-compose up -d api # REST API on :8000
|
