Clutter, a GObject-based library for creating fast, visually rich, graphical user interfaces, which works by manipulating a scene-graph of 2D surfaces, or 'actors,' inside a 3D space, is now at version 1.13.6.
Highlights of Clutter 1.13.6:
• Perform the picking in a separate buffer. By using a separate buffer, we can maintain the back buffer in a stable state and recycle its contents when doing clipped redraws;
• An experimental API for changing the draw timing has been added;
• Always request XInput 2.3 on the X11 backend;
• Startup with gnome-shell and cogl-1.14 has been fixed.
A complete list of changes can be found in the official announcement.
