+## [0.2.0] - 2026-03-20
+
+### Added
+- `thor_tray.py` — system tray launcher with status icon (green/amber/red/grey), Settings and Open Log Folder menu items
+- `thor_settings_dialog.py` — Tkinter settings dialog with first-run wizard; tabs for Connection, Paths, Scanning, Logging, Updates
+- Hardened auto-updater: three-layer download validation (100 KB floor, 50% relative size floor, MZ magic bytes), safer swap bat with 5-retry cap and `:fail` exit, `.exe.old` backup
+- Configurable update source: `update_source` (gitea / url / disabled), `update_url` for custom server
+- Remote push support: `update_available` flag in API heartbeat response triggers update regardless of `update_source` setting
+- `build.bat` — PyInstaller build script; outputs versioned exe for Gitea and plain copy for Inno Setup
+- `installer.iss` — Inno Setup installer script with startup shortcut
+- `_update_log()` helper writes timestamped `[updater]` lines to the watcher log
+- `log_tail` included in heartbeat payload (last 25 lines) for terra-view display
+- `run_watcher(state, stop_event)` pattern in `series4_ingest.py` for background thread use from tray
+
+### Changed
+- `series4_ingest.py` refactored into tray-friendly background thread module; `main()` retained for standalone use
+- Config key `sfm_endpoint` renamed to `api_url` for consistency with series3-watcher
+- Heartbeat payload now uses `source_id`, `source_type`, `version` fields matching terra-view WatcherAgent model
+- AppData folder: `ThorWatcher` (was not previously defined)
+
