# Version 0.3.20

> February 13, 2026

## <u>Features</u>

### Aardvark GPIO Support

* Added GPIO driver for the Aardvark USB adapter, enabling digital I/O control via `lager gpi` and `lager gpo` commands
* Supports reading and writing individual GPIO pins on the Aardvark adapter

### SPI Chip Select Control

* SPI commands now support manual vs automatic chip select (CS) assertion for both Aardvark and LabJack adapters
* Allows fine-grained control over CS pin behavior during multi-byte SPI transactions

### GPI Command Enhancements

* Added GPIO direction configuration support to `lager gpi` commands
* GPIO dispatcher now supports Aardvark and LabJack backends with direction control

## <u>Bug Fixes</u>

* Fixed SPI protocol files to use separate TX and RX data handling across all backends
* Fixed LabJack SPI driver transaction handling

## <u>Improvements</u>

* Improved natural sorting for CLI list outputs (nets, boxes, instruments, defaults, logs, and status views)
* Updated SPI base class and net abstractions for better multi-backend consistency
* Temporarily disabled FT232H backend code pending further testing
* Added comprehensive test scripts for Aardvark and LabJack I2C, SPI, and GPIO
