Release Notes

• Python async client — helix-db 0.3.3 adds reusable HTTPX connection pooling, concurrent requests, cancellation-safe response cleanup, and asynchronous embedded writer and reader clients.

• Open-source database — the engine moved out of helix-hyperscale into the public, modular helix-db workspace.
• New query planner — a dedicated logical and physical planning layer optimizes the typed operation-tree AST before execution.
• Embedded database — run the same engine and queries in process with memory, disk, or object storage.
• Vector prefiltering — traverse and filter an exact candidate set before vector ranking, so results cannot escape graph or permission boundaries.

• Row bindings — bind + projectBindings / projectDistinctBindings correlate values captured at different hops of a single traversal.
• Python SDK — new zero-dependency synchronous SDK (helix-db, imported as helixdb).
• CLI 3.0.6 — --path flag on helix add.

• Go SDK
• Better cache metrics for better query insights
• Query plan improvements
• helix chef command for local bootstrap
• CLI DX improvements
