-# HMAC File Server 3.2 Ultimate Fixed - Release Notes
-
-## 🚀 Major Release: Complete Configuration Modernization & Enhanced Multi-Platform Support
-
-**Release Date:** July 18, 2025  
-**Version:** 3.2 Ultimate Fixed  
-**Codename:** "Architecture Revolution"
-
----
-
-## 🎯 What's New in 3.2 Ultimate Fixed
-
-This release represents a **complete modernization** of HMAC File Server with comprehensive configuration updates, enhanced multi-architecture support, and improved project organization. Every aspect of the server has been refined for better performance, reliability, and ease of deployment.
-
-### 🔧 Configuration System Overhaul
-
-#### **Modernized Field Names**
-All configuration fields have been updated to use consistent, modern naming conventions:
-
-| **Old Field Name** | **New Field Name** | **Purpose** |
-|-------------------|-------------------|-------------|
-| `listenport` | `listen_address` | Server binding address and port |
-| `storagepath` | `storage_path` | File storage directory |
-| `metricsenabled` | `metrics_enabled` | Prometheus metrics toggle |
-| `readtimeout` | `read_timeout` | HTTP read timeout |
-| `writetimeout` | `write_timeout` | HTTP write timeout |
-| `idletimeout` | `idle_timeout` | HTTP idle timeout |
-
-#### **Extended Timeout Support**
-- **4800-second timeouts** for large file handling (up from 30s)
-- Perfect for multi-gigabyte file transfers
-- Eliminates timeout errors during long uploads/downloads
-- Configurable per operation type
-
-#### **Enhanced Deduplication System**
-```toml
-[deduplication]
-enabled = true
-directory = "./deduplication"
-maxsize = "1GB"  # Files larger than 1GB bypass deduplication for performance
-```
-
-#### **Dynamic Worker Scaling**
-```toml
-[server]
-enable_dynamic_workers = true
-worker_scale_up_thresh = 50    # Scale up when queue exceeds 50
-worker_scale_down_thresh = 10  # Scale down when queue drops below 10
-```
-
-### 🏗️ Multi-Architecture Build System
-
-#### **New Build Script Features**
-The `buildgo.sh` script now supports:
-
-- **Interactive Architecture Selection Menu**
-- **Cross-compilation Support** for:
-  - **AMD64** (x86_64) - Standard servers and desktops
-  - **ARM64** (AArch64) - Modern ARM processors, Raspberry Pi 4+
-  - **ARM32v7** - Older ARM devices, Raspberry Pi 3 and earlier
-- **Build-All Option** - Creates all architectures in one command
-- **Smart Binary Naming** - `hmac-file-server_amd64`, `hmac-file-server_arm64`, etc.
-- **Color-coded Output** for better user experience
-
-#### **Usage Examples**
-```bash
-# Interactive mode with menu
-./buildgo.sh
-
-# Menu options:
-# 1) AMD64 (x86_64)
-# 2) ARM64 (AArch64) 
-# 3) ARM32v7
-# 4) Build All Architectures
-# 5) Native Build
-```
-
-### 📁 Project Organization Improvements
-
-#### **Test Suite Reorganization**
-- All test scripts moved to dedicated `tests/` directory
-- Comprehensive test documentation in `tests/README.md`
-- Organized test categories:
-  - **Upload Tests** - Various file sizes and types
-  - **Network Tests** - Connection resilience and recovery
-  - **Performance Tests** - Load testing and benchmarks
-  - **Integration Tests** - Full system validation
-
-#### **Test Files Available**
-- `test_1mb.bin` / `test_1mb.txt` - Small file testing
-- `test_50mb.bin` - Medium file testing  
-- `test_215mb.bin` - Large file testing
-- `test_4gb.bin` / `test_4gb.txt` - Massive file testing
-- `chunk_0.bin` - Chunked upload testing
-
-### 🛡️ Security & Performance Enhancements
-
-#### **ClamAV Selective Scanning**
-```toml
-[clamav]
-# Only scan potentially dangerous file types
-scanfileextensions = [".txt", ".pdf", ".doc", ".docx", ".exe", ".zip", ".rar"]
-# Skip files larger than 200MB (ClamAV performance limit)
-maxscansize = "200MB"
-```
-
-#### **Smart File Handling**
-- **Deduplication** with hard-link optimization
-- **Pre-caching** for frequently accessed files
-- **Resumable uploads/downloads** for network resilience
-- **Chunked transfer** support for large files
-
-### 🐳 Docker & Deployment Improvements
-
-#### **Enhanced Docker Configuration**
-- Updated `dockerenv/config/config.toml` with all modern settings
-- Optimized container resource usage
-- Better volume mapping for persistent storage
-- Improved health check configurations
-
-#### **Production-Ready Defaults**
-```toml
-[server]
-max_upload_size = "10GB"
-cleanup_interval = "24h"
-max_file_age = "720h"  # 30 days
-min_free_bytes = "1GB"
-```
-
-### 📖 Documentation Overhaul
-
-#### **Completely Updated Documentation**
-- **README.md** - Modern configuration examples and usage
-- **WIKI.md** - Comprehensive configuration reference
-- **INSTALL.md** - Production deployment guide
-- **BUILD_GUIDE.md** - Multi-architecture build instructions
-- **NETWORK_RESILIENCE_GUIDE.md** - Network handling best practices
-
-#### **Configuration Best Practices**
-All documentation now includes:
-- **Timeout configuration** for different use cases
-- **Performance tuning** recommendations
-- **Security hardening** guidelines
-- **Troubleshooting** common issues

-## 🔄 Migration Guide
-
-### From 3.1.x to 3.2 Ultimate Fixed
-
-#### **Configuration Updates Required**
-1. **Update field names** in your `config.toml`:
-   ```bash
-   # Old format
-   listenport = ":8080"
-   storagepath = "/uploads"
-   metricsenabled = true
-   
-   # New format  
-   listen_address = ":8080"
-   storage_path = "/uploads"
-   metrics_enabled = true
-   ```
-
-2. **Update timeout values** for better large file support:
-   ```toml
-   [timeouts]
-   readtimeout = "4800s"
-   writetimeout = "4800s" 
-   idletimeout = "4800s"
-   ```
-
-3. **Enable new features**:
-   ```toml
-   [server]
-   enable_dynamic_workers = true
-   
-   [deduplication]
-   enabled = true
-   maxsize = "1GB"
-   ```
-
-#### **No Breaking Changes**
-- Backward compatibility maintained for core functionality
-- Old configuration files will work with warnings
-- Gradual migration supported
