## 🆕 Latest Release: v0.4.0 - Clean Database Schema

### What's New in This Release

#### Database Overhaul ✅
- ✅ **Clean schema design** - NO migrations, fresh init creates correct structure
- ✅ **Removed columns:** weight, height (never implemented)
- ✅ **Added litter_id** column to dogs table with foreign key
- ✅ **Parents table approach** - NO sire/dam columns in dogs table
- ✅ **Proper relationships** - Sire/dam stored in separate parents table
- ✅ **Database documentation** - Comprehensive DATABASE.md file

#### API Improvements
- ✅ **Fixed parent handling** - Properly inserts into parents table
- ✅ **Added logging** - See exactly what's happening during dog creation
- ✅ **Error handling** - Graceful fallbacks for missing data
- ✅ **Query optimization** - Select only existing columns

#### Server Improvements
- ✅ **Removed migrations** - Clean init.js is source of truth
- ✅ **Simplified startup** - Just calls initDatabase()
- ✅ **Better logging** - Clear console output with checkmarks
- ✅ **No schema detection** - Always uses correct structure

#### Documentation
- ✅ **DATABASE.md** - Complete schema reference
- ✅ **Updated README** - Current features and setup
- ✅ **Updated ROADMAP** - Accurate progress tracking
- ✅ **Troubleshooting guide** - Common issues and solutions

### Migration Instructions

For **fresh installs**, the database will initialize correctly automatically.

For **existing installations**, you need to start fresh:

```bash
# Backup your data
cp data/breedr.db data/breedr.db.backup

# Delete old database
rm data/breedr.db

# Pull latest code
git pull origin docs/clean-schema-and-roadmap-update

# Restart application (creates clean database)
docker-compose restart
```

**Note:** Parent relationship data cannot be automatically migrated due to schema change from columns to table. You'll need to re-enter parent relationships.
