# Release Notes

VisionPro Deep Learning 3.2.1 is a hotfix release of VisionPro Deep Learning 3.2

## Enhancements

- The AI Labeling Tool can now be used in the service client environment.

- The AI Labeling Tool now has the undo function.

- The Green Classify High Detail and the Green Classify High Detail Quick tools now also support processing with images smaller than 64 x 64 pixels.

- The Green Classify High Detail and the Green Classify High Detail Quick tools now also support training only with images smaller than 64 x 64 pixels.

Note:

- The VisionPro, Designer and VisionPro Deep Learning software require that a valid Cognex Security Dongle be installed directly to PCs running the software during all phases of operation (programming, processing, training, testing, etc.). Any attempts to temporarily remove, substitute, or share a Cognex Security Dongle may cause your system to operate incorrectly, and may result in the loss of data.

  When VisionPro Deep Learning is configured for the Client/Server functionality, and a computer has been configured as a server, the Cognex Security Dongle must be attached to the server, but the client(s) does not need a Cognex Security Dongle.

- Sample code is included with the VisionPro Deep Learning 3.2.1 installer. The resources for the sample code (VisionPro Deep Learning 3.2.1 Sample Code Resource.msi), which include images and workspaces, are available for download from the Cognex Support Site.
- For more information about new API functionality in this release, see the Cognex VisionPro Deep Learning Suite .NET Library and Cognex VisionPro Deep Learning Suite C API help files.
