Veyon 4.7.0 released

We’re happy to announce Veyon 4.7.0, a new release series for Veyon 4. Veyon 4.7 is the last minor release series of Veyon 4. One of the most long-awaited features is certainly the new screen selection menu in the remote access window. Also the overall performance and responsiveness has been improved thanks to a revised mechanism for sending and receiving control messages. Besides that, several issues from previous versions have been resolved.

In the Veyon Add-ons package you’ll find a preview version of the new Chat module which can be used for free until the end of March 2022. This chat module provides a chat window for teachers and students allowing them to write text messages interactively. The NetworkDiscovery add-on is now able to group hosts by certain parts of the hostname. For this a regular expression can be configured to extract the location and computer display name from the hostname. A computer with the hostname can be shown as c01 inside the location folder r101.

All downloads for this release are available in the download area.
