+# Archipelago v1.0.0 Release Notes
+
+**Release Date**: March 2026
+**Target Platform**: Debian 12 (Bookworm) — x86_64 and ARM64
+
+## What is Archipelago?
+
+Archipelago is a self-sovereign Bitcoin Node OS. Flash it to a USB drive, install on any x86_64 or ARM64 machine, and manage your personal server through a modern web interface. Run Bitcoin infrastructure, self-hosted apps, and Web5 identity — all from hardware you control.
+
+## Key Features
+
+### Bitcoin Infrastructure
+- **Bitcoin Knots** full node with pruning support
+- **LND** Lightning Network daemon with channel management UI
+- **Electrs** Electrum server for wallet connectivity
+- **BTCPay Server** for accepting Bitcoin payments
+- **Mempool** block explorer and fee estimator
+- **Fedimint** federation guardian and gateway
+
+### Self-Hosted Apps (20+)
+- **Storage**: File Browser, Immich, PhotoPrism, Nextcloud
+- **Productivity**: Penpot, OnlyOffice, Vaultwarden
+- **Media**: Jellyfin
+- **Search**: SearXNG (private search)
+- **AI**: Ollama (local LLMs with Claude, GPT, and open models)
+- **Network**: Tailscale VPN, Nginx Proxy Manager, Uptime Kuma
+- **Home**: Home Assistant
+- **Platform**: IndeedHub, Grafana monitoring
+
+### Web5 Identity
+- DID-based digital identity (Ed25519 + secp256k1 dual key)
+- Verifiable Credentials issuance and verification
+- Decentralized Web Node (DWN) for data sync
+- Nostr relay integration for node discovery
+
+### Federation
+- DID-authenticated peer-to-peer federation
+- Remote node monitoring and management
+- Bilateral trust with single-use invite codes
+- Tor hidden services for private communication
+
+### Security
+- AES-256-GCM encrypted secrets at rest
+- Container isolation: read-only root, capability dropping, non-root user
+- TOTP two-factor authentication with backup codes
+- Session management: HttpOnly cookies, SameSite=Strict, CSRF tokens
+- Rate limiting on sensitive endpoints
+- AppArmor profiles for container confinement
+- Per-endpoint input validation
+
+### System
+- Rust backend with JSON-RPC API (<1ms response time)
+- Vue 3 frontend with glassmorphism design
+- WebSocket real-time updates
+- Automated OTA updates with rollback
+- Tor hidden services for all apps
+- Goal-based onboarding wizard
+- Kiosk mode for dedicated hardware
+
+## Supported Hardware
+
+- **x86_64**: Any 64-bit PC, Intel NUC, mini PCs
+- **ARM64**: Raspberry Pi 5, other ARM64 SBCs
+- **Minimum**: 4GB RAM, 32GB storage (500GB+ recommended for Bitcoin)
+- **Recommended**: 8GB+ RAM, 1TB+ NVMe SSD
+
+## Installation
+
+1. Download the ISO for your architecture
+2. Flash to USB drive (use Balena Etcher or `dd`)
+3. Boot from USB on target hardware
+4. Follow the automated installer
+5. Access the web UI at `http://<device-ip>`
+6. Set your password and start the onboarding wizard
+
+## Known Limitations
+
+- Bitcoin initial block download takes 3-7 days depending on hardware
+- Some apps (BTCPay Server, Home Assistant) open in new tab due to X-Frame-Options
+- ARM64 builds may have slower container pulls due to less cached registry content
+- Tor hidden service generation takes 1-2 minutes on first boot
+
+## Upgrade from Beta
+
+If upgrading from v0.5.0-beta:
+1. Back up your data via Settings > Backup
+2. The OTA update system will handle the upgrade automatically
+3. If OTA fails, reflash with the v1.0.0 ISO (app data is preserved on separate partition)
+
+## Security Model
+
+Archipelago follows defense-in-depth:
+- **Network**: Nginx reverse proxy, Tor hidden services, VPN support
+- **Application**: Container isolation with Podman (rootless)
+- **Data**: AES-256-GCM encryption for secrets, 0600 file permissions
+- **Auth**: Argon2 password hashing, TOTP 2FA, session rotation
+- **Updates**: SHA-256 verified downloads with rollback capability
+
+See `docs/adr/` for architectural decision records on security choices.
+

+1. Fork the repository
+2. Create a feature branch (`feature/description`)
+3. Follow the coding standards in `CLAUDE.md`
