+## [1.4.3] - 2026-03-17
+
+### Added
+- Auto-updater now logs all activity to the watcher log file (`[updater]` prefix) — silent failures are now visible.
+- Configurable update source: `UPDATE_SOURCE = gitea` (default), `url`, or `disabled`. In `url` mode the watcher fetches `version.txt` and the `.exe` from a custom base URL (e.g. terra-view) instead of the Gitea API — enables updates on isolated networks that cannot reach Gitea. `disabled` turns off automatic checks while keeping the remote push path (from terra-view) functional.
+- New **Updates** tab in the Settings dialog to configure `UPDATE_SOURCE` and `UPDATE_URL`.
+
+### Fixed
+- Downloaded `.exe` is now validated before applying: absolute size floor (100 KB), relative size floor (50% of current exe), and MZ magic bytes check. A corrupt or truncated download is now rejected and logged rather than silently overwriting the live exe.
+- Swap `.bat` now backs up the current exe as `<exe>.old` before overwriting, providing a manual rollback copy if needed.
+- Swap `.bat` retry loop is now capped at 5 attempts — was previously infinite if the file remained locked.
+- Swap `.bat` now cleans up the temp download file on both success and failure.
+
+## [1.4.2] - 2026-03-17
+
+### Changed
+- Tray icon color now reflects watcher + API health rather than unit ages — green=API OK, amber=API disabled, red=API failing, purple=watcher error.
+- Status menu text updated to show `Running — API OK | N unit(s) | scan Xm ago`.
+- Units submenu removed from tray — status tracking for individual units is handled by terra-view, not the watcher.
+- Unit list still logged to console and log file for debugging, but no OK/Pending/Missing judgement applied.
+- `watcher_status` field added to heartbeat payload so terra-view receives accurate watcher health data.
+
+## [1.4.1] - 2026-03-17
+
+### Fixed
+- `config.ini` now saves to `AppData\Local\Series3Watcher\` instead of `Program Files` — fixes permission denied error on first-run wizard save.
+- Config path resolution in both `series3_tray.py` and `series3_watcher.py` updated to use `sys.frozen` + `LOCALAPPDATA` when running as a PyInstaller `.exe`.
+- Status menu item now uses a callable so it updates every time the menu opens — was showing stale "Starting..." while tooltip correctly showed current status.
+- Settings dialog now opens in its own thread — fixes unresponsive tabs and text fields while the watcher loop is running.
+- Tray icon reverted to plain colored dot — custom icon graphic was unreadable at 16px tray size. `.ico` file is still used for the `.exe` file icon.
+
+### Changed
+- Terra-View URL field in settings wizard now accepts base URL only (e.g. `http://192.168.x.x:8000`) — `/api/series3/heartbeat` endpoint appended automatically.
+- Test Connection button now hits `/health` endpoint instead of posting a fake heartbeat — no database side effects.
+- "terra-view URL" label capitalized to "Terra-View URL".
+- Default log path updated to `AppData\Local\Series3Watcher\agent_logs\series3_watcher.log`.
+- Installer now creates `agent_logs\` folder on install.
+- `BUILDING.md` added — step-by-step guide for building, releasing, and updating.

-# Series 3 Watcher — v1_0(py38-safe) for DL2
-
-**Target**: Windows 7 + Python 3.8.10  
-**Baseline**: v5_4 (no logic changes)
-
-## Files
-- series3_agent_v1_0_py38.py — main script (py38-safe)
-- config.ini — your config (already included)
-- series3_roster.csv — your roster (already included, this auto updates from a URL to a dropbox file)
-- requirements.txt — none beyond stdlib
-
-## Install
-1) Create `C:\SeismoEmitter\` on DL2
-2) Extract this ZIP into that folder
-3) Open CMD:
-   ```cmd
-   cd C:\SeismoEmitter
-   python series3_agent_v1_0_py38.py
-   ```
-(If the console shows escape codes on Win7, set `COLORIZE = False` in `config.ini`.)
-
-## Quick validation
-- Heartbeat prints Local/UTC timestamps
-- One line per active roster unit with OK/Pending/Missing, Age, Last, File
-- Unexpected units block shows .MLG not in roster
-- agent.log rotates per LOG_RETENTION_DAYS
