complete application suites.
the GtkFileSystem interface is no longer available, nor the filechooser
will load any GtkFileSystem implementation.
+* GtkComboBox now renders the popdown button insensitive when
+ the model is empty. Applications which want to populate the list
+ only before displaying it can set gtk_combo_box_set_button_sensitivity
+ to GTK_SENSITIVITY_ON, so that the button is always sensitive or
+ GTK_SENSITIVITY_OFF to make it insensitive respectively.
+
+* GtkAdjustment now enforces that values are restricted to the
+ range [lower, upper - page_size]. This has always been the documented
+ behaviour, and the recommended practice is to set page_size to 0
+ when using adjustments for simple scalar values, like in a slider
+ or spin button.
+
+* gdk-pixbuf will use GIO for mime type detection if possible. For
+ this to work, shared-mime-info needs to be installed and XDG_DATA_DIRS
+ set accordingly at configure time. Otherwise, gdk-pixbuf falls
+ back to its built-in sniffing implementation.

Release notes for 2.12
======================
* The gtk_notebook_set/get_group_id() functions were found to be insufficient
and have been deprecated in favour of gtk_notebook_set/get_group().

- various implementations of this signal in specific widgets. Great care

to work.

- is now passed the print settings on the command line with the

correctly destroyed. The screen-related functions have been deprecated,
