GTK+, a multi-platform toolkit for creating graphical user interfaces that provide a complete set of widgets, suitable for projects ranging from small one-off tools to complete application suites, is now at version 3.7.6.
According to the developers, GTK+ 3.7.6 incorporates new features and quite a few updates:
• The developers now use state flags for text direction: GTK_STATE_FLAG_LTR/RTL. gtk_style_context_set_direction() has been deprecated;
• GtkFrame now draws a background;
• The Broadway backend now installs a separate server: broadwayd;
• nvisible widgets now return a size of 0x0. This is an experimental change that makes GtkWidget::visible essentially behave the same way that "display: none" does in CSS.
A complete changelog, featuring all the updates and fixes, can be found in the official announcement
