# SoftBank Robotics documentation What's new in NAOqi 2.8?

# What’s new - 1.12.3

## NAO firmware

After a few weeks of life, NAO V4 needed to be settled, adjusted.

- Thermal model has been updated, in order to safely allow him to go further before saying “Motor hot”.
- Current limits of the motors have been pushed forward, so NAO V4 should be strong enough for the most difficult poses.
- Head Fan temperature/speed settings have been also updated in order to minimize unnecessary noise.
- WiFi transmission from the robot highly improved.

So don’t forget to update your robot: Updating robot system.

## Choregraphe

### Improved boxes

Walk to and Walk Toward boxes take less time to stop: in order to make NAO react more quickly, Walk to and Walk Toward boxes now use ALMotion stopWalk() to stop.

Stand up box has been fixed, its behavior is again symmetric.

### Installation on a multi user computer

License key activation on a multi user computer is now implemented for Choregraphe Suite.

So before installing, make sure you are logged as Administrator.

For further details, see Choregraphe suite - Installation Guide.

### Temporary directories cleaning

In version 1.12.0 and previous ones, Choregraphe could have created temporary directories in a wrong path where the Windows Cleaning disk command has not access.

This issue is now fixed.

To know how to clean manually these temporary files, see Windows only - Choregraphe temporary directories.
