Qt 6.8 LTS Released With XR Module, Lower RAM Usage & Quicker Start Times

Today marks the release of Qt 6.8 as not only a new feature release but also the latest long-term support (LTS) release for this open-source, cross-platform toolkit.

The Qt 6.8 LTS release introduces an XR module for new user experiences and allows for the development of Qt software on the likes of the Apple Vision Pro and Meta Quest 3 XR headsets. Qt 6.8 also now has official support for the Raspberry Pi 5 and NVIDIA AGX Orin hardware.
