+
+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.
+
+
+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
+ http://www.freedesktop.org/wiki/Standards/clipboard-manager-spec
+ must be running. A sample implementation of such a clipboard manager
+ is available at
+ http://people.imendio.com/andersca/archives/clipboard-manager-0.3.tar.gz
+ Applications can use the function gdk_display_supports_clipboard_persistence()
+ to find out if clipboard persistence is available.
+
+* Notification on clipboard ownership changes via GdkOwnerChange events
+ requires the XFIXES X extension. Applications can use the function
+ gdk_display_supports_selection_notification() to find out if ownerchip
+ change notification is available.
+
+* The icon theme code in GTK+ 2.6 follows the freedesktop.org icon theme
+ specification. Setting the XDG_DATA_DIRS environtment variable may be
+ necessary if your icons aren't installed in the default location
+ /usr/share/icons.
+
+* The icon theme code in GTK+ 2.6 can make use of mmap()able cache files
+ to avoid a lot of disk searching overhead. GTK+ includes a utility named
+ gtk-update-icon-cache to generate these cache files. For further details,
+ see the gtk-update-icon-cache man page or the GTK+ documentation.
+
+* To reduce code size and improve efficiency, GTK+, when compiled
+ with the GNU toolchain, has separate internal and external entry
+ points for exported functions. The internal names, which begin with
+ IA__, may be seen when debugging a GTK+ program.
+
+* The following functions have been deprecated in GTK+ 2.6:
+ gdk_pango_context_set_colormap
+ gtk_cell_renderer_editing_canceled
+
+* The new GtkFileChooser widget emphasizes simplicity and thus does
+ not provide a navigation entry by default when opening files.
+ Experienced command line users will likely want to make heavy use of
+ the location dialog brought up by the Control-L key shortcut.
+
+* The GTK+ libraries use an '_' prefix to indicate private symbols that
+ must not be used by applications. On some platforms, symbols beginning
+ with prefixes such as _gtk, _gdk, and _pango will be exported
+ from the library, on others not. In no case can applications
+ use these private symbols. In addition to that, GTK+ 2.6 makes several
+ symbols private which were not in any installed header files and
+ were never intended to be exported.
+
+* The gdk_pixbuf_xlib library included in the contrib/ directory
+ and the framebuffer GDK backend included in the gdk/linux-fb directory
+ of GTK+ are provided on an as-is basis and have not been tested at all.
+ No guarantees about the degree of workingness or about future
+ compatibility are provided.
+
+* On Unix, the assumption of GLib and GTK+ by default is that filenames on
+ the filesystem are encoded in UTF-8 rather than the encoding of the locale;
+ the GTK+ developers consider that having filenames whose interpretation
+ depends on the current locale is fundamentally a bad idea.
+
+ If you have filenames encoded in the encoding of your locale, then you
+ may want to set the G_FILENAME_ENCODING environment variable:
+
+ G_FILENAME_ENCODING=@locale
+ export G_FILENAME_ENCODING
+
+ (Earlier versions of GLib 2.x required a different environment variable
+ setting; G_BROKEN_FILENAMES=1 to achieve the same effect; this
+ is still supported, but G_FILENAME_ENCODING is preferred.)
+ Best integration of GTK+ 2.6 with the environment is achieved by
+ using a UTF-8 locale.
+
+ On Windows, filenames passed to GTK+ should always be in UTF-8, as
+ in GLib 2.6. This is different than in previous versions of GTK+
+ where the system codepage was used. As in GLib, for DLL ABI
+ stability, applications built against previous versions of GTK+ will
+ use entry points providing the old semantics.
+
+ When compiling against GTK+ 2.6, applications intended to be
+ portable to Windows must take the UTF-8 file name encoding into
+ 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
+==================
+
+Bugs should be reported to the GNOME bug tracking system.
+(http://bugzilla.gnome.org, product gtk+.) You will need to create an
+account for yourself.
+
+In the bug report please include:
+
+* Information about your system. For instance:
+
+ - What operating system and version
+ - What version of X
+ - For Linux, what version of the C library
+
+ And anything else you think is relevant.
+
+* How to reproduce the bug.
+
+ If you can reproduce it with one of the tests or demos built with GTK+,
+ such as demos/gtk-demo/gtk-demo, that would be most convenient. Otherwise,
+ please include a short test program that exhibits the behavior. As a
+ last resort, you can also provide a pointer to a larger piece of software
+ that can be downloaded.
+
+* If the bug was a crash, the exact text that was printed out when the
+ crash occured.
+
+* Further information such as stack traces may be useful, but is not
+ necessary. If you do send a stack trace, and the error is an X error,
+ it will be more useful if the stacktrace is produced running the test
+ program with the --sync command line option.
