## 📋 What's New in Detail
|
||
|
||
### Configuration Simplification
|
||
The biggest change in 3.2 is the revolutionary approach to configuration:
|
||
|
||
**Before (3.1.x):**
|
||
```toml
|
||
# 112 lines of complex configuration
|
||
[server]
|
||
listen_address = ":8080"
|
||
storage_path = "/srv/hmac-file-server/uploads"
|
||
metrics_enabled = true
|
||
metrics_path = "/metrics"
|
||
pid_file = "/var/run/hmac-file-server.pid"
|
||
max_upload_size = "10GB"
|
||
max_header_bytes = 1048576
|
||
cleanup_interval = "24h"
|
||
max_file_age = "720h"
|
||
# ... 100+ more lines
|
||
```
|
||
|
||
**Now (3.2):**
|
||
```toml
|
||
# Just 8 lines for production deployment!
|
||
[server]
|
||
listen_address = "8080"
|
||
storage_path = "/opt/hmac-file-server/data/uploads"
|
||
|
||
[security]
|
||
secret = "your-production-secret"
|
||
|
||
[logging]
|
||
level = "info"
|
||
file = "/var/log/hmac-file-server.log"
|
||
```
|
||
|
||
### Deduplication Intelligence
|
||
- **Fixed "File Not Found" Bug**: Existing file uploads now return proper success messages
|
||
- **Pre-Upload Detection**: Check file existence before upload attempt
|
||
- **Instant Responses**: No more false errors for duplicate files
|
||
- **Performance Optimized**: Hash-based deduplication with 1GB storage limits
|
||
|
||
### Queue & Performance Enhancements
|
||
- **Doubled Queue Capacity**: `uploadqueuesize` 50→100 for better throughput
|
||
- **Faster Worker Scaling**: Scale up at 40% queue depth instead of 80%
|
||
- **Extended Session Timeouts**: 30m→60m for large file reliability
|
||
- **Smart Timeout Management**: 4800s defaults for enterprise-grade transfers

## 🚀 Migration Guide
|
||
|
||
### From 3.1.x to 3.2
|
||
|
||
**Option 1: Keep Your Existing Config (Recommended)**
|
||
Your current `config.toml` will continue working without changes. The new defaults enhance performance automatically.
|
||
|
||
**Option 2: Migrate to Simplified Config**
|
||
1. Backup your current config: `cp config.toml config-3.1-backup.toml`
|
||
2. Generate new minimal config: `./hmac-file-server -genconfig > config-simple.toml`
|
||
3. Copy your custom values (storage_path, secret, etc.) to the new config
|
||
4. Test with: `./hmac-file-server -config config-simple.toml`
|
||
|
||
**Breaking Changes:**
|
||
- None! Full backward compatibility maintained
|
||
- Field mappings updated internally (transparent to users)
|
||
- New validation warnings for optimization opportunities
|
