 - **Tor integration** - Built-in hidden service support
 - **Updated seed nodes** - Latest v5.4.4 onion addresses
 - **Auto-installer** - One-command setup
 - **Full documentation** - Build instructions and usage guide
 
-**Note:** Binary is compressed with UPX (Ultimate Packer for Executables) for 80% size reduction. Decompresses automatically on execution with no performance penalty.

-**UPX Compression Benefits:**
-- 80% smaller binary (40MB → 1.6MB)
-- Faster download/transfer
-- No performance penalty (decompresses to RAM on load)
-- Fully reversible: `upx -d trianglesd`
-
 **Verify installation:**
 ```bash
 trianglesd --version
