- lemonade bench output now includes a hardware section covering CPU, GPU, RAM, OS, and backends.
- The llama.cpp backend now returns a clear error when an explicit device prefix contradicts the resolved backend.
- The Windows MSI installer now restores a saved custom per-user install location during upgrades.
