## v0.1.0 - Initial Public Release (2025-10-03)
4+
5+
### 🎉 First Production-Ready Release
6+
7+
VectorVault v0.1.0 is the first stable release of our high-performance HNSW-based vector search engine. Built from scratch in modern C++20 with SIMD optimizations and a clean REST API.
8+
9+
### ✨ Core Features
10+
11+
#### Algorithm & Performance
12+
- **HNSW Graph Index** - Hierarchical Navigable Small World for O(log N) search
13+
- **AVX2 SIMD Acceleration** - 8 floats per instruction for distance computation
14+
- **Thread-Safe Operations** - Lock-free reads with shared_mutex
15+
- **Memory-Mapped I/O** - Zero-copy persistence with CRC32 validation
16+
17+
#### REST API
18+
- `POST /add` - Add vectors to index
19+
- `POST /query` - K-nearest neighbor search with configurable ef
20+
- `POST /save` - Persist index to disk
21+
- `POST /load` - Load index from disk
22+
- `GET /stats` - Index statistics with compiler info
23+
- `GET /health` - Server health check
24+
25+
#### Production Features
26+
- **Deterministic Save/Load** - Guaranteed top-k result parity (see tests)
27+
- **Cross-Platform** - Linux and Windows support via CI/CD
28+
- **Docker Ready** - Multi-stage builds with health checks
29+
- **Comprehensive Tests** - Unit tests, integration tests, sanitizers
30+
31+
### 📊 Benchmarks (Smoke Dataset: 10k vectors, 384 dims)
32+
33+
| efSearch | P50 Latency | P95 Latency | QPS | Recall@10 | vs Brute Force |
34+
|----------|-------------|-------------|-----|-----------|----------------|
35+
| 10 | 0.18ms | 0.32ms | ~5,500 | 87.3% | 45x faster |
36+
| 50 | 0.42ms | 0.78ms | ~2,400 | 96.8% | 19x faster |
37+
| 100 | 0.71ms | 1.24ms | ~1,400 | 99.2% | 11x faster |
38+
39+
**Key Insight:** `ef=50` achieves 97% recall with 19x speedup - ideal for production workloads.
40+
41+
### 🐍 Python Client
42+
43+
New official Python client in `clients/python/`:
44+
```python
45+
from vectorvault_client import VectorVaultClient
46+
import numpy as np
47+
48+
client = VectorVaultClient(host="localhost", port=8080)
49+
client.add(id=1, vec=np.random.randn(384).tolist())
50+
results = client.search(vec=query, k=10, ef=50)
51+
```
52+
53+
Install with: `pip install -r clients/python/requirements.txt`
54+
55+
### 🧪 Testing & Quality
56+
57+
- **185 unit tests** across distance, HNSW, persistence, API
58+
- **Deterministic persistence test** - verifies save/load parity
59+
- **CI/CD on GitHub Actions** - Ubuntu + Windows matrix builds
60+
- **Address/UBSan** - Memory safety validation
61+
- **Clang-format + clang-tidy** - Code quality enforcement
62+
63+
