A high-performance, in-memory vector database written in Rust, designed for semantic search and top-k nearest neighbor queries in AI-driven applications, with binary file persistence for durability.

## Recent releases

| Version | Date | Urgency | Changes |
| --- | --- | --- | --- |
| `vectorizer-3.4.0` | 2026-06-06 | High | A Helm chart for Vectorizer - High-performance vector database |
| `vectorizer-3.3.0` | 2026-05-04 | High | A Helm chart for Vectorizer - High-performance vector database |
| `vectorizer-3.1.0` | 2026-04-29 | High | A Helm chart for Vectorizer - High-performance vector database |
| `vectorizer-3.0.12` | 2026-04-25 | High | A Helm chart for Vectorizer - High-performance vector database |
| `vectorizer-3.0.0` | 2026-04-21 | High | A Helm chart for Vectorizer - High-performance vector database |
| `v3.0.0` | 2026-04-21 | High | ### Removed - **Standalone JavaScript SDK dropped (`sdks/javascript/`).** The TypeScript SDK ships compiled CommonJS + ESM and is fully usable from plain JavaScript, so maintaining a parallel JS-only package doubled CI/release work for no functional difference. The published `@hivehub/vectorizer-sdk-js` package on npm remains installable; no new releases will ship. Migrate by replacing `@hivehub/vectorizer-sdk-js` with `@hivehub/vectorizer-sdk` — the runtime API and import paths are identical. |
| `vectorizer-2.5.16` | 2026-04-03 | Medium | A Helm chart for Vectorizer - High-performance vector database |
| `v2.5.16` | 2026-04-03 | Medium | Fix: POST search/scroll/recommend/count are now served locally on followers instead of being redirected to leader. These are read operations. Image: ghcr.io/hivellm/vectorizer:2.5.16 |
| `vectorizer-2.5.15` | 2026-04-03 | Medium | A Helm chart for Vectorizer - High-performance vector database |
| `v2.5.15` | 2026-04-03 | Medium | Fix: vector inserts now replicate to followers in Raft mode. Root cause: upsert_points() only checked static master_node (always None in Raft), not ha_manager.master_node(). Also includes NetworkError fix for Raft elections.
