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 * Scroll events have been separated from button events, and smooth
79 scrolling has been added with a separate event mask. Widgets now
80 need to have either GDK_SCROLL_MASK or GDK_SMOOTH_SCROLL_MASK in
81 their event mask to receive scroll events.
83 * GTK+ now uses <Primary> instead of <Control> in keyboard accelerators,
84 for improved cross-platform handling. This should not affect
85 applications, unless they parse or create these accelerator
88 * The tacit assumption that the Alt key corresponds to the MOD1
89 modifier under X11 is now a hard requirement.
91 * The beagle search backend for the file chooser has been dropped.
92 Tracker is the only supported search backend on Linux now.
94 * GtkNotebook has been changed to destroy its action widgets when
95 it gets destroyed itself. If your application is using action
96 widgets in notebooks, you may have to adjust your code to take
99 * GtkApplication no longer uses the gtk mainloop wrappers, so
100 it is no longer possible to use gtk_main_quit() to stop it.
102 * The -uninstalled variants of the pkg-config files have been dropped.
104 * Excessive dependencies have been culled from Requires: lines
105 in .pc files. Dependent modules may have to declare dependencies
106 that there were getting 'for free' in the past.
109 Release notes for 3.2
110 =====================
112 * The accessible implementations for GTK+ widgets have been integrated
113 into libgtk itself, and the gail module does not exist anymore. This
114 change should not affect applications very much.
116 Release notes for 3.0
117 =====================
119 * GTK+ 3 is a major new version of GTK+, which is parallel installable
120 with GTK+ 2.x. For information about porting applications from GTK+ 2.x
121 to GTK+ 3, see the file:
123 docs/reference/gtk/html/migrating.html
127 http://library.gnome.org/devel/gtk/3.0/migrating.html
129 * Note that the library sonames in this release have been changed from
130 libgtk-3.0 and libgdk-3.0 to libgtk-3 and libgdk-3, to prevent the
131 library versions from going backwards, compared to the 2.90/91/99
132 releases. Applications will have to be recompiled.
