## 2025-10-18 - 4.0.0 - BREAKING CHANGE(core): Complete migration to Deno runtime

**MAJOR RELEASE: NUPST v4.0 is a complete rewrite powered by Deno**

This release fundamentally changes NUPST's architecture from Node.js-based to Deno-based,
distributed as pre-compiled binaries. This is a **breaking change** in terms of installation and
distribution, but configuration files from v3.x are **fully compatible**.

### Breaking Changes

**Installation & Distribution:**

- **Removed**: Node.js runtime dependency - NUPST no longer requires Node.js
- **Removed**: npm package distribution (no longer published to npmjs.org)
- **Removed**: `bin/nupst` wrapper script
- **Removed**: `setup.sh` dependency installation
- **Removed**: All Node.js-related files (package.json, tsconfig.json, pnpm-lock.yaml,
  npmextra.json)
- **Changed**: Installation now downloads pre-compiled binaries instead of cloning repository
- **Changed**: Binary-based distribution (~340MB self-contained executables)

**CLI Structure (Backward Compatible):**

- **Changed**: Commands now use subcommand structure (e.g., `nupst service enable` instead of
  `nupst enable`)
- **Maintained**: Old command format still works with deprecation warnings for smooth migration
- **Added**: Aliases for common commands (`nupst ls`, `nupst rm`)

### New Features

**Distribution & Installation:**

- Pre-compiled binaries for 5 platforms:
  - Linux x86_64
  - Linux ARM64
  - macOS x86_64 (Intel)
  - macOS ARM64 (Apple Silicon)
  - Windows x86_64
- Automated binary releases via Gitea Actions
- SHA256 checksum verification for all releases
- Installation from Gitea releases via updated `install.sh`
- Zero dependencies - completely self-contained binaries
- Cross-platform compilation from single codebase

**CI/CD Automation:**

- Gitea Actions workflows for continuous integration
- Automated release workflow triggered by git tags
- Automatic binary compilation for all platforms on release
- Type checking and linting in CI pipeline
- Build verification on every push

**CLI Improvements:**

- New hierarchical command structure with subcommands
- `nupst service` - Service management (enable, disable, start, stop, restart, status, logs)
- `nupst ups` - UPS device management (add, edit, remove, list, test)
- `nupst group` - Group management (add, edit, remove, list)
- `nupst config show` - Display configuration
- `nupst --version` - Show version information
- Better help messages organized by category
- Backward compatibility maintained with deprecation warnings

**Technical Improvements:**

- Deno runtime for modern TypeScript/JavaScript execution
- Native TypeScript support without compilation step
- Faster startup and execution compared to Node.js
- Smaller memory footprint
- Built-in permissions system
- No build step required for development

### Migration Guide

**For Users:**

1. Stop existing v3.x service: `sudo nupst disable`
2. Install v4.0 using new installer:
   `curl -sSL https://code.foss.global/serve.zone/nupst/raw/branch/main/install.sh | sudo bash -s -- -y`
3. Your configuration at `/etc/nupst/config.json` is preserved and fully compatible
4. Enable service with new CLI: `sudo nupst service enable && sudo nupst service start`
5. Update systemd commands to use new syntax (old syntax still works with warnings)

**Configuration Compatibility:**

- All configuration files from v3.x work without modification
- No changes to `/etc/nupst/config.json` format
- All SNMP settings, thresholds, and group configurations preserved

**Command Mapping:**

```bash
# Old (v3.x)              → New (v4.0)
nupst enable              → nupst service enable
nupst disable             → nupst service disable
nupst start               → nupst service start
nupst stop                → nupst service stop
nupst status              → nupst service status
nupst logs                → nupst service logs
nupst add                 → nupst ups add
nupst edit [id]           → nupst ups edit [id]
nupst delete <id>         → nupst ups remove <id>
nupst list                → nupst ups list
nupst test                → nupst ups test
nupst group add           → nupst group add (unchanged)
nupst group edit <id>     → nupst group edit <id> (unchanged)
nupst group delete <id>   → nupst group remove <id>
nupst group list          → nupst group list (unchanged)
nupst config              → nupst config show
```

### Technical Details

**Commit History:**

- `df6a44d`: Complete migration with Gitea Actions workflows and install.sh updates
- `9efcc4b`: CLI reorganization with subcommand structure
- `5903ae7`: Cross-platform compilation scripts
- `a649c59`: Deno migration with npm: and node: specifiers
- `5f4f3ec`: Initial migration to Deno

**Files Changed:**

- Removed: 11 files (package.json, tsconfig.json, pnpm-lock.yaml, npmextra.json, bin/nupst,
  setup.sh)
- Added: 3 Gitea Actions workflows (ci.yml, release.yml, README.md)
- Modified: 14 TypeScript files for Deno compatibility
- Updated: install.sh, .gitignore, readme.md
- Net reduction: -10,242 lines (93% reduction in repository size)

**Dependencies:**

- Runtime: Deno v1.x (bundled in binary, no installation required)
- SNMP: npm:net-snmp@3.20.0 (bundled in binary via npm: specifier)
- Node.js built-ins: Accessed via node: specifier (node:fs, node:child_process, etc.)

### Benefits

**For Users:**

- **Faster Installation**: Download single binary instead of cloning repo + installing Node.js + npm
  dependencies
- **Zero Dependencies**: No Node.js or npm required on target system
- **Smaller Footprint**: Single binary vs repo + Node.js + node_modules
- **Easier Updates**: Download new binary instead of git pull + npm install
- **Better Security**: No npm supply chain risks, binary checksums provided
- **Platform Support**: Official binaries for all major platforms

**For Developers:**

- **Modern Tooling**: Native TypeScript support without build configuration
- **Faster Development**: No compilation step during development
- **CI/CD Automation**: Automated releases and testing
- **Cleaner Codebase**: 93% reduction in configuration files
- **Cross-Platform**: Compile for all platforms from any platform

### Known Issues

- Windows ARM64 not supported (Deno limitation)
- Binary sizes are larger (~340MB) due to bundled runtime (trade-off for zero dependencies)
- First-time execution may be slower on some systems (binary extraction)

### Acknowledgments

This release represents a complete modernization of NUPST's infrastructure while maintaining full
backward compatibility for user configurations. Special thanks to the Deno team for creating an
excellent runtime that made this migration possible.
