* The default selected day for GtkCalendar is now the current day in the
month, not the first day in the month. The current month and year
were already used.
* GDK is no longer put into threaded mode automatically when
g_thread_init() has been called. In order to use the
global GDK thread mutex with gdk_threads_enter() and
gdk_threads_leave(), you must call gdk_threads_init() explicitely.
gdk_threads_init() calls g_thread_init() if it hasn't already
been called, so you can typically change your call to g_thread_init()
into a call to gdk_threads_init().
If you aren't using GDK and GTK+ functions from multiple threads,
there is no reason to call gdk_threads_init().
