Installation
============
See the file 'INSTALL'
+
+Release notes for 2.20
+======================
+
+* GtkStatusbar now has a message area (see gtk_status_bar_get_message_area)
+ which makes it easy to place additional widgets inside the statusbar
+ frame or to replace the label widgets. Previously, this was only possible
+ by accessing the innards of the statusbar widget directly. Applications
+ which are doing so may need some adjustments, since the addition of the
+ message area changed the internal widget hierarchy.
+
+* GtkBuilder no longer sets the "name" property of widgets to the ID
+ attribute of the <object>. Use gtk_buildable_get_name() instead of
+ gtk_widget_get_name() to obtain the ID.
+
+* GTK+ now includes introspection data, as a consequence, it gained a
+ dependency on gobject-introspection. It is possible to build without
+ introspection by passing --disable-introspection to configure.
+
+
+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.
+
+* 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
+======================
+
+* 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
======================
gtk_range_set_[upper/lower]_stepper_sensitivity() functions to
prevent the arrows from being rendered insensitive.
-Release notes
-=============
+* 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://library.gnome.org/devel/gobject/unstable/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.
+
+
+Release notes for 2.8
+=====================
+
+* GTK+ 2.8 and Pango 1.10 require the cairo library.
+
+* The default theme has been renamed to "Raleigh". Existing configurations
+ specifying the "Default" theme name should still work.
+
+* The GtkTreeView::enable-search property has been changed to control
+ only typeahead search, not the C-f keybinding to start an interactive
+ search. To turn off interactive searching completely, you have to
+ set GtkTreeView::search-column to -1.
+
+* The restriction on using the same cell renderer in multiple columns
+ of a GtkTreeView is now more strictly enforced.
+
+* In GTK+ 2.8, GtkCalendar uses nl_langinfo() (if available) to determine
+ the first day of the week. Thus, it is possible to select the first day
+ of the week independently from the language, by setting LC_TIME.
+
+* In GTK+ 2.8, the gtk-update-icon-cache utility includes image data
+ in the icon caches, which will make the icon cache files larger than
+ the one produced by GTK+ 2.6. This change will reduce the memory
+ overhead of icon themes at runtime, since all GTK+ applications can
+ share the image data in memory.
+
+* In 2.8, GDK emits GdkEventGrabBroken events when a keyboard or pointer
+ grab is broken. On X11, this can happen if the same application grabs
+ again, or if the window used for the grab becomes unviewable. It happens
+ more often on Win32. Applications which use grabs should pay attention
+ to these events and do the necessary cleanups when the grab is lost.
+* The GIOChannel code for sockets on win32 has been rewritten.
+ Applications who make non-trivial use of GIOChannels on win32 should
+ be watched for possible problems.
+
+* GLib 2.8 uses atomic operations to implement reference counting, thus
+ g_object_ref/unref, g_closure_ref/sink/unref and g_iochannel_ref/unref
+ can be used without locking in multithreaded applications. Note that
+ other modifications, like concurrent setting of properties still require
+ locking.
+
+* g_convert() and related character set conversion functions have been
+ fixed to emit pending shift states and to not cache iconv descriptors
+ across multiple calls, since that is problematic for some encodings.
+ Note that these functions are not suitable for streaming conversions;
+ use g_iconv() to do streaming conversion.
+
+
+Release notes for 2.6
+=====================
* GTK+ 2.6 supports clipboard persistency. To make use of this feature,
a clipboard manager following the specification at
consideration, and use the gstdio wrappers to access files whose
names have been constructed from strings returned from GTK+ or GLib.
+
How to report bugs
==================
it will be more useful if the stacktrace is produced running the test
program with the --sync command line option.
