---

## [1.2.1] - 2026-03-03

### Changed
- Changed the name of the program to "series3-agent", this was done to align with the s4/thor agent and because it represents the program's functionality better.
- All instances of "emitter" changed to agent.
- config.ini added to .gitignore, replaced with a template example file.
- README.md updated to reflect changes.

---

## [1.2.0] - 2025-12-04

### Changed
- Removed roster CSV dependency and all Dropbox refresh/hot-reload logic; heartbeat now only enumerates `.MLG` files.
- Added `MAX_EVENT_AGE_DAYS` filter to ignore stale events and log when no recent activity exists.
- Simplified heartbeat output/logging to show detected units only; logging hardened to never crash the agent.

---

## [1.1.1] - 2025-12-02

### Added
- Example `config.ini` now ships with API heartbeat settings enabled (`API_ENABLED`, `API_URL`, `API_INTERVAL_SECONDS`, `SOURCE_ID`, `SOURCE_TYPE`).

---

## [1.1.0] - 2025-12-01

### Added
- Standardized SFM telemetry payload builder and periodic HTTP heartbeat POST via `urllib`.
- Config support for API heartbeat (`API_ENABLED`, `API_URL`, `API_INTERVAL_SECONDS`, `SOURCE_ID`, `SOURCE_TYPE`); payload includes file path/size metadata.

### Changed
- Refactored scanner to retain file paths and header sniff cache; reformatted logging/ANSI handling.

---

## [1.0.1] - 2025-11-20

### Added
- `API_URL` config key and `report_to_server` per-unit POST hook (adds `requests` dependency).

### Changed
- Example `config.ini` roster URL updated; merged into `main`.

---

## [1.0.0] - 2025-11-17

### Added
- **Automatic roster refresh** from Dropbox at a configurable interval (`ROSTER_REFRESH_MIN_SECONDS`).
- **Hot-reload** of roster file without restarting the script.
- **Failsafe reload:** if the new roster is missing or invalid, the previous good roster is retained.
- **Atomic roster downloads** (temp file in-place replace) to avoid partial/corrupted CSVs.
- **Startup config echo** printing WATCH_PATH, ROSTER_FILE, and ROSTER_URL visibility.
- **Active / Bench / Ignored** unit categories for clearer fleet status mapping.

### Fixed
- Removed stray `note=note_suffix` bug in the Unexpected Units section.
- Removed duplicate `import time`.
- Removed duplicate roster load during startup (roster now loads once).
- Cleaned indentation for Python 3.8 compatibility.

### Changed
- Reset versioning from legacy `v5.9 beta` to **v1.0.0** (clean semver baseline).
- Main script normalized as `series3_emitter.py` (later renamed to `series3_agent.py` in v1.2.1).
