+## [1.3.5] - 2026-03-03
+
+### Changed
+- Hardened subprocess handling and synced monitor docs/metadata.
+
+
+## [1.3.3] - 2026-02-11
+
+### Changed
+
+- **Subprocess env hardening:** `monitor.py` now uses an allowlist for web-search-plus subprocess environment (`PATH`, `HOME`, `LANG`, `TERM` + search provider keys only).
+- **Discord delivery flow:** Removed webhook-style delivery from skill docs/flow; Discord alerts are now emitted as structured JSON (`DISCORD_ALERT`) for OpenClaw agent delivery (same pattern as Telegram).
+- **No direct HTTP calls:** Alerting/search integration is documented as agent-mediated JSON output + subprocess execution, without direct outbound HTTP from topic-monitor skill code.
+
+## [1.3.2] - 2026-02-11
+
+### 🆕 Real Alerting System
+
+The alerting system is now fully functional (was a stub before):
+
+- **Telegram Alerts:** Send immediate alerts for high-priority findings
+- **Multi-Channel Support:** Telegram, Discord, and Email
+- **Smart Filtering:** Importance scoring determines what gets alerted
+
+### Changed
+
+- **State Files:** Now stored in `.data/` directory (configurable via `TOPIC_MONITOR_DATA_DIR`)
+- **Telegram ID:** Configured via `TOPIC_MONITOR_TELEGRAM_ID` environment variable (no hardcoded values)
+- **web-search-plus Path:** Now relative by default, configurable via `WEB_SEARCH_PLUS_PATH`
+- **No Hardcoded Paths:** All paths and IDs are now configurable
+
+### Environment Variables
+
+New environment variables for configuration:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `TOPIC_MONITOR_TELEGRAM_ID` | — | Telegram chat ID for alerts |
+| `TOPIC_MONITOR_DATA_DIR` | `.data/` | State and findings directory |
+| `WEB_SEARCH_PLUS_PATH` | Relative | Path to web-search-plus script |
+
+### Migration
+
+If you had hardcoded paths in config.json, update to use environment variables:
+```bash
+export TOPIC_MONITOR_TELEGRAM_ID="your_telegram_id"
+```
+
+## [1.2.1] - 2026-02-04
+
+- Privacy cleanup: removed hardcoded paths and personal info from docs
