+## [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.

-- series3_agent_v1_0_py38.py — main script (py38-safe)

-- 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
