    Avoid unwanted drag cancel animations
    
    GTK+ is now being more careful about dealing with tabs
    disappearing in the middle of a drag - which is exactly
    what the current gedit code appears to be doing, from
    the GtkNotebook viewpoint. To avoid this, use a new function
    that was introduced for this purpose in GtkNotebook.

 Installation
 ============
 
-gedit requires GTK+ >= 3.14.0, GtkSourceView >= 3.14.0 and
+gedit requires GTK+ >= 3.15.7, GtkSourceView >= 3.15.3 and
 libpeas >= 1.7.x libraries. It also has a run-time dependency on an
 icon theme for its icons. If gedit fails to display icons, installing
 GNOME's default adwaita-icon-theme is a simple way of providing them.
