Release Notes

Knowledge graph + multi-device sync

The graph link + 4-provider capture + signed release milestone. Captures from ChatGPT, Claude, and Gemini are now Pro (Grok remains free); links surface automatically as conversations cluster; sync protocol goes live for multi-device.

New

• Knowledge graph linker — TF-IDF cosine over titles + tags; inserts persisted links with 0.7+ similarity. Endpoints at /api/kg/* on cluster-hub.
• Multi-device sync — AES-256-GCM end-to-end encryption. Per-device keys derived via domain-separated SHA-256. Last-writer-wins on conflict. Endpoints at /api/sync/*.
• All 4 providers capture — Grok (free), Claude + ChatGPT + Gemini (Pro). License-gated via /api/license/check.
• Signed release pipeline — GPG-signed commits + tags + .asc artefacts. SBOM via Syft + CycloneDX/SPDX merge.

Improved

• Bundle size — AppImage target reduced from 77 MB to <30 MB via LTO + strip + panic=abort.
• Codemagic CI — iOS + Android automated signing + submission to TestFlight + Play Console internal track.

TabMind v0.7.0 — full DOM capture

Captures complete conversation DOM, including tool calls, code blocks, and embedded media. Documents 4-page capture (grok / chatgpt / claude / gemini) with stable selectors.

New

• Full DOM capture — preserves structure for tool calls, code blocks, file uploads, image previews.
• Performance budgets — capture completes within 250ms p95 on a 4-page session.
• Manifest v0.7.0 — schema migration handled in-place.

Phase 2 extractors + capture registry

Per-vendor extractor pattern, with a registry that makes new providers a single config line. Rust trait + JS bridge.

Phase 1 — capture + search

First public release. Captures conversations with full text search, knowledge graph storage, and offline playback.
