 # Changelog
 
+## 2025-03-28 - 3.0.0 - BREAKING CHANGE(core)
+Add multi-UPS support and group management; update CLI, configuration and documentation to support multiple UPS devices with group modes
+
+- Implemented multi-UPS configuration with an array of UPS devices and groups in the configuration file
+- Added group management commands (group add, edit, delete, list) with redundant and non-redundant modes
+- Revamped CLI command parsing for UPS management (add, edit, delete, list, setup) and group subcommands
+- Updated readme and documentation to reflect new configuration structure and features
+- Enhanced logging and status display for multiple UPS devices
+
 ## 2025-03-26 - 2.6.17 - fix(logger)
 Preserve logbox width after logBoxEnd so that subsequent logBoxLine calls continue using the set width.

 ## Features
 
+- **Multi-UPS Support**: Monitor and manage multiple UPS devices from a single installation
+- **Group Management**: Organize UPS devices into groups with different operating modes
+  - **Redundant Mode**: Only shutdown when ALL UPS devices in a group are in critical condition
+  - **Non-Redundant Mode**: Shutdown when ANY UPS device in a group is in critical condition
 - Monitors UPS devices using SNMP (v1, v2c, and v3 supported)
 - Automatic shutdown when battery level falls below threshold
 - Automatic shutdown when runtime remaining falls below threshold

 ## Configuration
 
-NUPST provides an interactive setup to configure your UPS:
+NUPST supports monitoring multiple UPS devices organized into groups. You can set up your UPS devices using the interactive commands:
 
 ```bash
-nupst setup
+# Add a new UPS device
+nupst add
+
+# Create a new group
+nupst group add
+
+# Assign UPS devices to groups
+nupst group edit <group-id>
 ```
 
-This will guide you through setting up:
+### Configuration File Structure
-- UPS IP address and SNMP settings
-- Shutdown thresholds for battery percentage and runtime
-- Monitoring interval
-- Test the connection to your UPS
 
-Alternatively, you can manually edit the configuration file at `/etc/nupst/config.json`. A default configuration will be created on first run:
+The configuration file is located at `/etc/nupst/config.json`. Here's an example of a multi-UPS configuration:

+  - `name`: Friendly name for the group
+  - `mode`: Group operating mode ('redundant' or 'nonRedundant')
+  - `description`: Optional description of the group
+
+### Group Modes
+
+- **Redundant Mode**: The system will only initiate shutdown if ALL UPS devices in the group are in critical condition (below threshold). This is ideal for redundant power setups where one UPS can keep systems running.
+  
+- **Non-Redundant Mode**: The system will initiate shutdown if ANY UPS device in the group is in critical condition. This is useful for scenarios where all UPS devices must be operational for the system to function properly.
