 **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

 - **Changed**: Installation now downloads pre-compiled binaries instead of cloning repository

 **CLI Structure (Backward Compatible):**
- **Changed**: Commands now use subcommand structure (e.g., `nupst service enable` instead of `nupst enable`)

 - [ ] Should we keep tsconfig.json for npm package compatibility?
 - [ ] Should we fully migrate to Deno APIs (Deno.readFile) or keep node:fs?
 - [ ] Should we remove the `bin/nupst` wrapper or keep it?
 - [ ] Should setup.sh be completely removed or kept for dependencies?

 ### Risk Areas:
+
 - ⚠️ SNMP native addon compatibility in compiled binaries (HIGH PRIORITY TO TEST)
