# 🚀 Arela v3.10.0 - SHIPPED!

**Published:** 2025-11-14  
**Status:** ✅ LIVE on NPM  
**Package Size:** 897.8 kB  
**Total Files:** 455

## 🎉 What We Shipped

### 1. Contract Validation with Dredd ✅
**Prevent API drift automatically**

```bash
arela validate contracts
arela validate contracts --contract openapi/workout-api.yaml
arela validate contracts --server-url http://localhost:8080
```

**Prevents:**
- API drift between spec and implementation
- Breaking changes shipping to production
- Undocumented endpoints
- Schema mismatches

### 2. API Versioning & Drift Detection ✅
**Manage breaking changes safely**

```bash
arela version detect-drift
arela version create workout --version 2
```

**Detects:**
- 🔴 Removed endpoints (CRITICAL)
- 🔴 Removed operations (CRITICAL)
- 🟠 Missing responses (HIGH)
- 🟡 Schema field/type changes (MEDIUM)

### 3. Windsurf Workflow Integration ✅
**Structured processes for development**

```
/research-driven-decision
```

Systematic approach to making evidence-based technical decisions.

## 📊 Impact

**This release completes the API-Contract-First workflow:**

1. ✅ Generate contracts from code (v3.8.0)
2. ✅ Generate clients from contracts (v3.9.0)
3. ✅ **Validate contracts match implementation (v3.10.0)** 🆕
4. ✅ **Detect and manage breaking changes (v3.10.0)** 🆕

**VSA + API-Contract-First architecture is now fully supported!**
