The GNOME team has released their GNOME 3.17.4 (development snapshot) desktop environment for Linux.
This release features IP addresses for vms in gnome-boxes, improved Wayland hi-dpi support in mutter, MathML support in orca and performance improvements in tracker.
You can also see events from different boots in gnome-logs and a new view in the GTK+ file chooser.
GNOME 3.17.4 introduces a new application preview: gnome-todo. And of course bug fixes, besides many small improvements.
Please be aware this is a development snapshot, so use it with caution.
