# Release Notes

As of VisionPro Deep Learning 3.1, Cognex brings a couple of brand new features that steer your machine vision journey to the new round of excellence. For the updates made in API, see API.

## Windows 11 is now supported

Now VisionPro Deep Learning 3.1 supports Windows 11

## RTX™ 40 series are tested

VisionPro Deep Learning supports on RTX™ 40 series which are RTX 4070 Ti, RTX 4080 and RTX 4090. It is tested on RTX 4080 and 4090.

## Minor improvements

- Improved the processing speed for High Detail tool by optimizing the internal logic, including the mask functionality.

- Due to internal logic improvements, the training speed of Red Analyze High Detail tool has been partially enhanced.

- In the Auto mode of Parameter search, remaining and elapsed time are displayed during the search.

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 3.1 installer. The resources for the sample code (VisionPro Deep Learning 3.1 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.
