Veyon 4.7.1 released

We’re happy to announce Veyon 4.7.1, the first maintenance release of Veyon 4.7.x. Besides the usual bug fixes, this release adds some minor new features such as clipboard synchronization during remote control and the possibility to open multiple remote access windows at once. In the Veyon Add-ons package you’ll find the first release of the new Screen Recorder add-on. It allows teachers to record the student’s screens into video files e.g. during exams and is a very useful supplement to the well known screenshot feature.

Like all other add-ons before, starting with 4.7.1 the LDAP Pro add-on can now be tested without a license for a limited time. LDAP Pro 4.7.1 also received a bug fix to make it resolve entries of computer locations properly when using computer groups or computer location attributes. Finally, Veyon Configurator no longer crashes when access control test functions are used and LDAP Pro 4.7.1 is set as the access control groups backend.

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