# Version 0.2.36

> December 18, 2025

## <u>Breaking Changes</u>

### Terminology Restructure: Gateway/DUT to Box

This release standardizes terminology across the entire codebase, replacing "gateway" and "DUT" (Device Under Test) with the unified term "box".

**CLI Changes:**

* The `--dut` option is now `--box` (hidden alias kept for backward compatibility)
* The `--gateway` option is now `--box` where applicable
* All help text and error messages now use "box" terminology

**Configuration Changes:**

* The `DUTS` key in `.lager` configuration files is now `BOXES` (backward compatible - old format is still read)
* Box storage functions renamed (e.g., `load_duts()` → `load_boxes()`)

**Directory Structure:**

* `gateway/` directory renamed to `box/`
* `gateway/lager/lager/` flattened to `box/lager/`
* `gateway_http_server.py` renamed to `box_http_server.py`
* `start_lager.sh` renamed to `start_box.sh`
* Deployment scripts renamed:
  * `setup_and_deploy_gateway.sh` → `setup_and_deploy_box.sh`
  * `secure_gateway_firewall.sh` → `secure_box_firewall.sh`
  * `verify_gateway_security.sh` → `verify_box_security.sh`

**Migration:**

* Existing `.lager` configuration files will continue to work
* The `--dut` CLI option works as a hidden alias for `--box`
* Update any scripts or automation to use the new `--box` option

## <u>Migration Guide</u>

### For CLI Users

lager supply voltage --dut my-device 3.3

# After
lager hello --box my-device
lager supply voltage --box my-device 3.3
```

### For Script Authors

Update any automation scripts to use the new flag names:

```bash theme={null}
# Before
BOX_NAME="my-device"
lager hello --dut $BOX_NAME

# After
BOX_NAME="my-device"
lager hello --box $BOX_NAME
```

### For Box Administrators

Update deployment commands:
