Veyon 4.8.0 released

We’re happy to announce Veyon 4.8.0, the first release of the latest and last minor release series of Veyon 4. Veyon 4.8 introduces image quality control mechanisms to better meet bandwidth contraints, especially in Wi-Fi networks. A static image quality can now be configured for monitoring mode and remote access views. The demo server controls the image quality dynamically based on the used bandwidth between two key frames and the configured bandwidth limit.

The Windows version of Veyon is now based on the latest Qt 6.5 framework as well as OpenSSL 3 and UltraVNC Also the build environment has been updated to Debian 11 (i.e. GCC 10 and MinGW runtime 8). This allowed us to enable Link Time Optimization (LTO) resulting in better overall performance. At the same time, Veyon 4.8 requires Windows 10 or newer and will not run e.g. on Windows 7 or Windows Server 2008.

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