GNOME Boxes lead developer Felipe Borges has been overhauling the application with a major rewrite and today announced the new beta release. GNOME Boxes has migrated to using the GTK4 toolkit and libadwaita. The new GNOME Boxes code can also handle installing Microsoft Windows 11 now without needing any manual workarounds for Secure Boot or TPM requirements.
The new GNOME Boxes code also introduces a VSOCK device for accessing VM contexts and other improvements. With the revamped GNOME Boxes, it's also shifting to a Flatpak-first and only model for distributing of new GNOME Boxes releases.
If you’re shipping an out of date package with your own customizations then uses should at least be redirected towards your own bug tracking services instead of sending them to waste the maintainers time on bugs that either have already been fixed or aren’t present without the tweaks applied by the distribution.
