2026-06-10 ### Major — NEXCA Engine Integration - **MQTT**: nexca v1.4.11 এর `listenMqtt.js` দিয়ে replace — better stability, autoReconnect, jitter - **E2EE**: Signal Protocol encrypted conversations support (`api.connectE2EE()`, `api.listenE2EE()`, `api.e2ee.*`) - **sessionGuard**: appstate auto-save every 3min, corruption guard, auto-backup (`api.sessionGuard()`) - **sendBroadcast**: rate-limited multi-thread broadcast (`api.sendBroadcast(msg, threadIDs, opts)`) - **sendMessage**: nexca version (MQTT-first + HTTP fallback, better attachment handling) - **OldMessage**: nexca HTTP-only send, `sendMessageDM` shorthand - All fca-eryxenx API files preserved (GoatBot compatible signatures) - Copyright: fca-eryxenx v4.0.0 by EryXenX --- ## [3.1.0] - 2026-06-09 ### Fixed (MQTT stability — account safety) - **`connectMqtt.js`: `isActiveClient()` guard added** — stale/previous MQTT client এর events আর process হবে না। Multiple reconnect race condition বন্ধ। - **`connectMqtt.js`: Subscribe → wait SUBACK → then publish** — আগে `topics.forEach(subscribe)` করে immediately publish হতো। Facebook এটাকে invalid sequence ধরে "Connection refused: No subscription existed" দিয়ে socket বন্ধ করত। এখন callback-based subscribe দিয়ে SUBACK পাওয়ার পরেই publish। - **`connectMqtt.js`: `connectTimeout` 5000ms → 12000ms** — slow network এ premature timeout থেকে logout বন্ধ। - **`connectMqtt.js`: `T_MS_WAIT_TIMEOUT_MS` 5000ms → 8000ms** — slow server response এ needless reconnect cycle বন্ধ। - **`connectMqtt.js`: `close`/`disconnect` handlers এ `autoReconnect` যোগ** — আগে close/disconnect এ reconnect হতো না। বট offline হয়ে যেত। - **`connectMqtt.js`: Previous client cleanup before new connection** — stale client memory leak বন্ধ। - **`connectMqtt.js`: Reconnect jitter (±400ms)** — একসাথে অনেক reconnect storm কমাবে। --- ## [3.0.29] - 2026-02-22 - Maintenance release (hotfix / version bump). ## [3.0.30] - 2026-02-26 - **Security & supply chain** - Removed legacy/self-dependency and old HTTP stack (`request`, `sqlite3`, `npmlog`), pinned `axios` to a secure version, and cleaned up `npm audit` findings (no Critical/High CVEs in runtime deps). - Added `SECURITY.md`, restricted the published files via `package.json.files` (no Horizon refs, no bundled node_modules) and wired `npm publish --provenance` into CI for verifiable builds. - **Event-driven core** - Promoted the `api` object to an `EventEmitter` with lifecycle events: `sessionExpired`, `autoLoginSuccess`, `autoLoginFailed`, `checkpoint`/`checkpoint_282`/`checkpoint_956`, `loginBlocked`, `rateLimit`, `networkError`. - Hooked these into `loginParser` and the HTTP layer so consumers can react to login, checkpoint, and network conditions without brittle error-string matching. - **Thread/User info & DB-backed anti-get-info** - Refactored `getThreadInfo` and `getUserInfo` to use GraphQL batch calls with optional SQLite caching (via Sequelize models), reducing repeated Facebook requests and aligning with Horizon-style anti-get-info behavior. - Added configuration toggles in `fca-config.json` (`antiGetInfo.AntiGetThreadInfo`, `antiGetInfo.AntiGetUserInfo`) to switch between DB-backed and legacy behaviors when needed. - **Remote control & analytics** - Introduced a lightweight WebSocket **remote control client** (`src/remote/remoteClient.js`) driven by `remoteControl` config, emitting `remoteConnected`, `remoteDisconnected`, `remoteStop`, `remoteBroadcast`, and `remoteMessage` events for integration with external dashboards. - Taught the MQTT layer to update per-thread statistics in SQLite via an atomic `Thread.increment("messageCount")` on each message, enabling future analytics (e.g. “most active threads”) without impacting message latency. - **Docs & utilities** - Updated `README.md`, `DOCS.md`, and `docs/ARCHITECTURE.md` to document the new event system, DB caching behavior, remote control, proxy configuration, and the optional `broadcast` helper. ## [3.0.28] -
