 ## [Unreleased]
 
+## [0.7.2] - 2025-11-01
+
+### Added
+- **`comet output` now supports filtering to a specific output key** - Added optional third argument to get individual output values
+  - Usage: `comet output <stack> <component> <key>`
+  - Outputs only the value (without `key = value` format) for easier use in scripts
+  - Example: `ENDPOINT=$(comet output production gke cluster_endpoint)`
+  - Returns clear error if key doesn't exist
