v0.10.0-beta.1

Latest · Beta

Local context graphs in Python and TypeScript

Use the Rust context core directly in your app, without a server or API key.

What changed
Adds LocalContextGraph, incremental source updates, cited token-budgeted context, and verifiable snapshots and deltas.
Requirements
Python 3.14 or Node 24.10–24.x (ESM). Bundled local worker: macOS ARM64.
Compatibility & upgrade
Keeps the 0.9.4 remote APIs. The CLI, daemon, and MCP runtime remain on 0.9.4.

v0.9.4

Developer preview

Context selection and workflow recovery

Adds the opt-in balanced_v4 context profile and resumable workflow sessions across the SDKs.

What changed
Improves retrieval and packing, adds risk-aware evidence selection, and saves workflow checkpoints for recovery.
Requirements
Runtime: Apple-silicon macOS. Python 3.14; Node 24.10–24.x (ESM).
Compatibility & upgrade
Context ABI v1 and storage v5 are unchanged. Enable balanced_v4 explicitly; verify a backup before upgrading.

v0.9.2

Developer preview

Incremental storage and faster restarts

Introduces storage v5 with incremental deltas and checkpoints, plus better duplicate-content handling.

What changed
Reduces repeated persistence and recovery work while preserving source citations and the balanced_v1 selection profile.
Requirements
Runtime: Apple-silicon macOS. Python 3.14. Companion SDK archives are available on GitHub.
Compatibility & upgrade
Remote API v1 stays compatible. Migrate v4 storage into a separate v5 target; rollback uses a verified backup, never an in-place downgrade.

Requirements
Python 3.14 and a configured CIGAR service with explicit authorization.
Compatibility & upgrade
Install hol-cigar; import cigar_sdk. The local context graph is available starting with 0.10.0 beta 1.
