4 This is GTK+ version @GTK_VERSION@. GTK+ is a multi-platform toolkit for
5 creating graphical user interfaces. Offering a complete set of widgets,
6 GTK+ is suitable for projects ranging from small one-off projects to
7 complete application suites.
9 GTK+ is free software and part of the GNU Project. However, the
10 licensing terms for GTK+, the GNU LGPL, allow it to be used by all
11 developers, including those developing proprietary software, without any
12 license fees or royalties.

34 Bugs should be reported to the GNOME bug tracking system.
35 (http://bugzilla.gnome.org, product glib.) You will need
36 to create an account for yourself.
38 In the bug report please include:
40 * Information about your system. For instance:
42 - What operating system and version
43 - For Linux, what version of the C library
45 And anything else you think is relevant.
47 * How to reproduce the bug.
49 If you can reproduce it with one of the test programs that are built
50 in the tests/ subdirectory, that will be most convenient. Otherwise,
51 please include a short test program that exhibits the behavior.
52 As a last resort, you can also provide a pointer to a larger piece
53 of software that can be downloaded.
55 * If the bug was a crash, the exact text that was printed out
56 when the crash occured.
58 * Further information such as stack traces may be useful, but
65 Patches should also be submitted to bugzilla.gnome.org. If the
66 patch fixes an existing bug, add the patch as an attachment
69 Otherwise, enter a new bug report that describes the patch,
70 and attach the patch to that bug report.
72 Patches should be in unified diff form. (The -up option to GNU diff.)
78 * The accessibility bridge code that exports accessible objects
79 on the bus is now used by default; atk-bridge has been converted
80 into a library that GTK+ links against. To void the linking,
81 pass --without-atk-bridge when configuring GTK+.
83 * GDK threading support has been deprecated. It is recommended to
84 use g_idle_add(), g_main_context_invoke() and similar funtions
85 to make all GTK+ calls from the main thread.
87 * GTK+ now follows the XDG Base Directory specification for
88 user configuration and data files. In detail,
89 * $XDG_CONFIG_HOME/gtk-3.0/custom-papers is the new location
90 for $HOME/.gtk-custom-papers
91 * $XDG_CONFIG_HOME/gtk-3.0/bookmarks is the new location
92 for $HOME/.gtk-bookmarks
93 * $XDG_DATA_HOME/themes is preferred over $HOME/.themes
94 * $XDG_DATA_HOME/icons is preferred over $HOME/.icons.
95 Existing files from the old location will still be read
96 if the new location does not exist.
98 * $HOME/.gtk-3.0 is no longer in the default module load path.
99 If you want to load modules from there, add it to the GTK_PATH
100 environment variable.
102 Release notes for 3.4
103 =====================
105 * Scroll events have been separated from button events, and smooth
106 scrolling has been added with a separate event mask. Widgets now
107 need to have either GDK_SCROLL_MASK or GDK_SMOOTH_SCROLL_MASK in
108 their event mask to receive scroll events. In addition, the
109 GdkScrollDirection enumeration has gained a new member,
110 GDK_SCROLL_SMOOTH, so switch statements will have to be amended
113 * GTK+ now uses <Primary> instead of <Control> in keyboard accelerators,
114 for improved cross-platform handling. This should not affect
115 applications, unless they parse or create these accelerator
118 * The tacit assumption that the Alt key corresponds to the MOD1
119 modifier under X11 is now a hard requirement.
121 * The beagle search backend for the file chooser has been dropped.
122 Tracker is the only supported search backend on Linux now.
124 * GtkNotebook has been changed to destroy its action widgets when
125 it gets destroyed itself. If your application is using action
126 widgets in notebooks, you may have to adjust your code to take
129 * GtkApplication no longer uses the gtk mainloop wrappers, so
130 it is no longer possible to use gtk_main_quit() to stop it.
132 * The -uninstalled variants of the pkg-config files have been dropped.
134 * Excessive dependencies have been culled from Requires: lines
135 in .pc files. Dependent modules may have to declare dependencies
136 that there were getting 'for free' in the past.
139 Release notes for 3.2
140 =====================
142 * The accessible implementations for GTK+ widgets have been integrated
143 into libgtk itself, and the gail module does not exist anymore. This
144 change should not affect applications very much.
146 Release notes for 3.0
147 =====================
149 * GTK+ 3 is a major new version of GTK+, which is parallel installable
150 with GTK+ 2.x. For information about porting applications from GTK+ 2.x
151 to GTK+ 3, see the file:
153 docs/reference/gtk/html/migrating.html
157 http://library.gnome.org/devel/gtk/3.0/migrating.html
159 * Note that the library sonames in this release have been changed from
160 libgtk-3.0 and libgdk-3.0 to libgtk-3 and libgdk-3, to prevent the
161 library versions from going backwards, compared to the 2.90/91/99
162 releases. Applications will have to be recompiled.
