-Release notes for 2.18
-======================
-
-* gtk_tooltip_set_custom now accept a NULL custom_widget to unset the
- old custom_widget. Custom_widget does not get destroyed when the
- tooltip goes away.
-
-* JPEG2000 support is no longer enabled by default. It must be
- explicitly turned on, by passing --with-libjasper to configure.
-
-* GDK has been reworked to implement 'client-side windows'. This offers
- exciting new possibilities, such as transformed, offscreen rendering,
- but it breaks some long-standing assumptions that applications may
- have about GDK windows. Setting the environment variable
- GDK_NATIVE_WINDOWS makes GDK create a native X11 window for each
- GDK window, which might make problematic applications work better.
-
-* GTK+ calls signal (SIGPIPE, SIG_IGN) during initialization, to ignore
- SIGPIPE signals, since these are almost never wanted in graphical
- applications. If you do need to handle SIGPIPE for some reason, reset
- the handler after gtk_init(), but notice that other libraries (e.g.
- libdbus or gvfs) might do similar things.
-
-Release notes for 2.16
-======================
-
-* Password entries now display a caps-lock warning. This can be turned off
- with the caps-lock-warning property.
-
-* Various orientation-related functions have been deprecated in favour
- of the new GtkOrientable interface: gtk_scale_button_get_orientation,
- gtk_scale_button_set_orientation, gtk_toolbar_set_orientation.
-
-* The action-proxy interaction has been changed. Widgets that operate as
- proxies have to implement the GtkActivatable interface now. GtkActivatable
- implementation are responsible for syncing their appearance with the
- action and for activating the action. All GTK+ widgets that are commonly
- used as proxies implement the GtkActivatable interface.
-
-* The handling of keyboard shortcuts has been changed, to help with a
- longstanding complaint about the way GTK+ handles multiple layouts. GTK+
- now only uses keys from groups other than the current group if they are
- not present in the current group.
-
-Release notes for 2.14
-======================
-
-* gtkitemfactory.h is now completely deprecated.
- As gtkactiongroup.h and gtkstock.h no longer include the gtkitemfactory.h
- header, this might break application using gtk_item_factory_* symbols
- without including gtkitemfactory.h - even though this behaviour has never
- been supported in the first place.
-
-* The GtkFileSystem semi-private interface has been removed.
- The GTK+ filechooser implementation now uses GIO directly, which has
- rendered external filesystem implementations unnecessary. Consequently,
- 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.
-
-* In the early 2.14.x releases, GtkAdjustment was changed to enforce
- 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.
- Due to the large number of applications that are affected by this
- change, the behaviour has been reverted to the old behaviour in
- 2.14.3, with an explicit warning that this change will be
- reintroduced in 2.90.
-
-* 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
-======================
-
-* gtk_about_dialog_get/set_name() were deprecated in favour of
- gtk_about_dialog_get/set_program_name(), the GtkAboutDialog now uses the
- "program-name" property instead of the conflicting "name" property.
-
-* The gdk-pixbuf tiff loader now requires libtiff 3.6.0 or later.
-
-* Support for Windows 9x/ME has officially been removed. It hasn't worked
- since 2.6 anyway.
-
-* The GtkTextBufferTargetInfo enumeration values have been changed from
- G_MAXUINT-0, G_MAXUINT-1, G_MAXUINT-2, etc, to -1, -2, -3 to stay within
- ANSI C limits.
-
-* A change in the handling of _NET_WM_USER_TIME properties on toplevel
- windows can cause deadlock problems with window managers that are using
- GDK for drawing decorations. In particular, metacity <= 2.18.0 is affected
- by this. The problem has been fixed in metacity 2.18.1.
-
-* Semi-private GtkTextLayout api has changed: new GtkTextLayout method
- invalidate_cursors(), and new functions gtk_text_layout_invalidate_cursors()
- and gtk_text_layout_cursors_changed(), which should be used in place of
- gtk_text_layout_invalidate() and gtk_text_layout_changed() if invalidation
- is due to marks moved or changed selection; new GtkTextLineDisplay structure
- member. Source compatibility is preserved; binary compatibility may break
- only if GtkTextLineDisplay structure was created on stack or as a part
- of another structure (in particular GnomeCanvas and its clones do not need
- recompiling).
-
-* Another new signal has been added to GtkNotebook. The new signal
- is called create-window, so this name can no longer be used for signals
- in objects derived from GtkNotebook.
-
-* 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().
-
-* The move-focus signal has been moved to GtkWidget, to unify the
- various implementations of this signal in specific widgets. Great care
- has been taken to make sure that all code using this signal continues
- to work.
-
-* An unused and hardly visible GtkFrame has been removed from the menu
- widget hierarchy when GtkComboBox::appears-as-list style property is
- set. Any RC file applying a different style to any widget below the
- widget path "gtk-combobox-popup-window.GtkFrame" should take into
- account that the frame no longer exists.
-
-* The external print preview application used by GtkPrintOperationPreview
- is now passed the print settings on the command line with the
- --print-settings parameter pointing to a temp file containing the
- settings. The preview application assumes ownership of the file and
- should delete it once it does not need it anymore. The --print-settings
- commandline option is understood by Evince 0.9.0 and newer. To use a
- different print preview application, change the gtk-print-preview-command
- setting in your gtkrc file, e.g. gtk-print-preview-command = "ggv %f"
-
-* GtkMenuShell is now defined as an abstract type. It was already
- documented as an abstract class, and there is little reason to
- instantiate it.
-
-* The GtkTooltips struct (this is the old tooltips API) is now considered
- private. Code that used to access this struct, in particular the
- tips_data_list field, will need to change. All of the old tooltips
- API has been deprecated in favour of a new implementation and
- API. This affects all of the gtk_tooltips_ functions, and functions
- which take a GtkTooltips argument, such as gtk_tool_item_set_tooltip()
- and gtk_menu_tool_button_set_arrow_tooltip().
-
-* The memory management of the GtkRecentManager object has been changed,
- as using the screen didn't guarantee that the singleton instance was
- correctly destroyed. The screen-related functions have been deprecated,
- and should not be used anymore; the GtkRecentManager instance returned by
- the gtk_recent_manager_get_default() function is guaranteed to be valid
- for the entire lifetime of an application.
-
-* A number of interfaces that have been superseded by newer interfaces for
- a long time have finally been deprecated. This includes
- gtk_widget_ref/unref(), gtk_rc_style_ref/unref() and the old file selector.
-
-* The various coordinate systems in use in GtkTreeView widgets have
- been clarified in the documentation, and in the cause of doing so,
- the functions gtk_tree_view_widget_to_tree_coords() and
- gtk_tree_view_tree_to_widget_coords() have been deprecated in
- favour of a new family of gtk_tree_view_convert_ functions.
-
-* gtk_menu_item_remove_submenu() has been deprecated in favour of
- gtk_menu_item_set_submenu (..., NULL).
-
-* gtk_default_draw_check() has been fixed to really decrease the
- indicator size by one pixel to ensure an odd size instead of
- accidentially increasing it.
- Consequently, gtk_cell_renderer_toggle_render() could be fixed to
- not subtract 1 from the size passed to gtk_paint_option(), which
- was just a workaround for above off-by-two for even sizes (theme
- engines now get the real indicator size passed).
- The default toggle size of GtkCheckMenuItem and GtkCellRendererToggle
- has been changed to 13 to be consistent with GtkCheckButton.
- The only visible change with default settings is that the indicator in
- GtkCellRendererToggle has changed its size from 11 to 13 and is now
- consistent with menus and toggle buttons.
-
-* GTK+ has always required that gtk_init() (or a variant thereof) is
- called before any other GTK+ function. Some applications call functions
- like gtk_clipboard_get() to check if they need to call gtk_init(),
- anyway. A change in GLib 2.14 has recently broken this unsupported
- practise. It is worth pointing out that calling gtk_init() twice
- does no harm.
-
-
-Release notes for 2.10
-======================
-
-* The hexadecimal Unicode input feature has been reworked. It no longer
- blocks the use of the sixteen Ctrl-Shift-<hex digit> key sequences. Now
- it only uses Ctrl-Shift-u.
-
-* A memory leak in GtkStyle handling has been fixed. This may expose bugs
- in third-party widgets which forget to call gtk_style_attach() in their
- realize functions.
-
-* Range widgets like GtkScrollbar now render their arrows insensitive
- when the slider is at the end. Applications which react to arrow
- clicks even if the slider is at the end may want to use the new
- gtk_range_set_[upper/lower]_stepper_sensitivity() functions to
- prevent the arrows from being rendered insensitive.
-
-* GtkObject now uses the "floating reference" support in GObject.
- GTK_OBJECT_IS_FLOATING() will still work, but direct checking
- of the GTK_FLOATING flag will no longer detect the floating
- reference. Details about floating references can be found in the docs:
- http://developer.gnome.org/doc/API/2.0/gobject/gobject-The-Base-Object-Type.html#floating-ref
-
-* Accelerators like (_F) are now stripped from labels when they are
- displayed in toolbars. If this is not wanted, the feature can be
- suppressed by inserting a Unicode control character, e.g ZWNJ.
-
-* The pixbuf theme engine can now customize expanders (in GtkTreeView
- and GtkExpander) and resize grips, using the new EXPANDER and
- RESIZE_GRIP function values.
-
-* Dialogs created by gtk_about_dialog_new() no longer hide automatically
- when the user clicks close. It is the applications responsibility to
- hide or destroy the dialog.
-
-* Several new signals have been added to GtkNotebook. Care has been taken
- to choose signal names which do not collide with signals added by well-known
- derived classes. The names which can no longer be used for signals in
- objects derived from GtkNotebook are page-reordered, page-removed and
- page-added.
-
-* Due to the interface changes in the file chooser backend interface,
- the GTK+ ABI version has been bumped to 2.10.0. Third-party filesystem
- backends have to be ported to the new interface, other modules, such as
- theme engines, input method modules or pixbuf loaders have to be rebuilt
- so that they are installed in the right place for GTK+ to find them.
