AgentDB v0.7.0
Major New Features
- CRDT-Based Sync Engine — Replicate AgentDB instances with Hybrid Logical Clocks, operation logs, and configurable conflict resolution (Last-Writer-Wins / First-Writer-Wins)
- Tri-Modal Hybrid Query — Blend vector ANN + graph traversal + FTS BM25 in a single query with tunable alpha/beta/gamma weights
- WASM OPFS Persistence — Browser databases now survive page reloads via the Origin Private File System API (load-save pattern with SQLite serialize/deserialize)
- LangChain Integration — langchain-agentdb package implementing VectorStore + BaseChatMessageHistory
- LlamaIndex Integration — llamaindex-agentdb package implementing BasePydanticVectorStore + BaseChatStore
- Ruby SDK — Full FFI bindings (40+ functions) with idiomatic Ruby API, RSpec test suite
CLI Improvements
- agentdb version — print version + target triple
- agentdb export <path> [--table <name>] — dump database as SQL statements
- agentdb completions --shell <bash|zsh|fish|powershell> — generate shell completions
Test Coverage
- 73 new async API tests (Rust)
- 91 new Node.js tests covering full API surface
- Python test suite (10 test classes)
- 16 sync module tests
- 8 tri-modal query tests
Dependency Migrations
- rand 0.8 → 0.10 (thread_rng → rng, gen → random)
- criterion 0.5 → 0.8 (removed deleted html_reports feature)
CI/CD Fixes
- Fixed Snap/WinGet/Chocolatey publish workflows (root cause: actions/checkout@v7 doesn't exist)
- crates.io publish: pinned MSRV 1.95.0, added --locked
- Coverage threshold raised to 80%, now includes async+ffi code paths
- Node.js smoke test class name bug fixed
Documentation
- ROADMAP.md aligned with actual v0.6.0 release content
- README roadmap table corrected
- Manual publish steps documented for Snap/WinGet/Chocolatey/crates.io
