# Version 0.3.11

> January 15, 2026

## <u>Bug Fixes</u>

### Supply TUI Force-Close Lock Release

* Fixed VISA resource lock not being released when terminal window is force-closed
* Added `on_unmount()` lifecycle hook to ensure WebSocket cleanup on any exit
* Prevents "Resource busy" errors after ungraceful TUI termination

### Keysight Power Supply Output State

* Fixed bug where changing voltage on Keysight E36200 power supplies would disable the output
* Removed unnecessary `disable_output()` call from driver initialization
* Output state is now preserved when changing voltage or current setpoints

### Voltage/Current Command Feedback

* Fixed missing confirmation output for `lager supply voltage` and `lager supply current` commands
* Commands now display "\[OK] Voltage set to X.XV" or "\[OK] Current set to X.XA" on success
