[0.7.3] - 2026-07-10

Agent-ready WeChat data layer — Ship an Agent Skill for Claude Code, Codex, Cursor, and other compatible agents to query and subscribe to local WeChat data
Cross-conversation timeline — Add GET /api/v1/timeline for time-bounded message reads across all conversations in one request, with pagination, ordering, message-type filters, and privacy filtering
Compact timeline output — Return the conversation identity, sender, direction, timestamp, type, and snippet needed by memory, archive, and reporting agents without duplicating raw message payloads

Reuse SQLCipher derived keys — Cache per-database derived keys and reuse them across open, count, refresh, and reopen paths instead of repeating the 256k-round KDF
Bound timeline memory — Keep only the candidates required for the requested page rather than retaining the complete cross-conversation history during sorting
Faster long-running server queries — Reuse warm database connections for batch timeline reads, avoiding one CLI process and HTTP round trip per conversation

Rewrite the README around user-facing capabilities: local database access, real-time subscriptions, Agent integration, automation, memory, CRM, and workflow use cases
Document Release installation and the bundled Agent Skill
Update project dependencies and GitHub Actions
Restore clean cargo fmt --check, cargo clippy -- -D warnings, and full-workspace test baselines

Decrypt WeChat databases — Automatically decrypt WeChat macOS (4.1.7.x / 4.1.8.x) encrypted databases
Extract encryption keys — Two methods available: key extract (recommended, uses LLDB) and key scan (memory scan, requires sudo)
Browse contacts — Search and view your WeChat contacts with details like phone, signature, region, labels, and memo
Browse conversations — List recent conversations with unread counts and last message preview
Query messages — Filter messages by contact, group, date range, or message type, with pagination support
Full-text search — Search across all conversations by keyword, with automatic index building
Export conversations — Export chats to TXT or JSON, including images, voice messages, videos, and file attachments
Real-time monitoring — Watch for new messages as they arrive with watch command
Media handling — Decrypt images, convert WeChat voice messages to standard audio, decode WeChat-format images (WXGF), and decrypt video channel videos
HTTP server mode — Run as a local HTTP service with REST API and real-time event stream (SSE) for integration with other apps
Privacy filtering — Hide specific contacts or group members from query and server results
Environment check — doctor command verifies all prerequisites are met
Parallel processing — Large exports process images, voice, and video in parallel for faster completion
