1. GTK+ 2.99.3 released (Matthias Clasen)

Subject: GTK+ 2.99.3 released
Content-Type: text/plain; charset="UTF-8"
GTK+ 2.99.3 is now available for download at:
This is the last beta release of what will become GTK+ 3.0.
The amount of changes that went into this release was larger
than anticipated, and we will therefore give it at least a
week of little to no changes before declaring 3.0 done.
* GTK+ 3 will be parallel installable with GTK+ 2.x, and
this release has been prepared to test this by renaming
all .pc files, libraries, include paths, and so forth,
to include a '3.0' component.
An exception to this is the gtk-update-icon-cache utility,
for which parallel installation would make little sense.
Distributors can choose to build GTK+ 3 with the
--enable-gtk2-dependency configure option to avoid building
gtk-update-icon-cache, and rely on the GTK+ 2.x version of
the utility instead.
* GTK+ 3 removes deprecated API from the GTK+ 2.x series and makes
struct members unavailable that have been GSEALed in 2.x. Therefore,
applications can be prepared for porting to GTK+ 3 by making sure
that they build with -DGTK_DISABLE_DEPRECATED and -DGSEAL_ENABLE.
For more information about porting concerns, see the porting guide
that is included in the API doc:
The removal of GSEALed struct members and deprecated APIs has been
completed. Any deprecated APIs in this release will not be removed
before GTK+ 4.0.
* Bugs should be reported to http://bugzilla.gnome.org.
What is GTK+
GTK+ is a multi-platform toolkit for creating graphical user
interfaces. Offering a complete set of widgets, GTK+ is suitable for
projects ranging from small one-off tools to complete application
GTK+ has been designed from the ground up to support a range of
languages, not only C/C++. Using GTK+ from languages such as Perl and
Python (especially in combination with the Glade GUI builder) provides
an effective method of rapid application development.
GTK+ is free software and part of the GNU Project. However, the
licensing terms for GTK+, the GNU LGPL, allow it to be used by all
developers, including those developing proprietary software, without
any license fees or royalties.

GTK+ is a large project and relies on voluntary contributions.
We are actively searching for new contributors in various areas
and invite everyone to help project development.

Overview of Changes in GTK+ 2.99.3
* This release adds some forgotten padding to class structs,
and thus breaks ABI for a last time before 3.0
* Many Introspection annotation improvements
* We no longer build the gtk-update-icon-cache utility, and
use a preexisting one, if --enable-gtk2-dependency is passed
* GtkBuilder can now fill GtkComboBoxText and GtkMenToolButton
widgets with data, as well as GtkFileFilters and GtkTextTagTables
* GtkImage now has a ::use-fallback property to allow generic
fallback with GIcons and icon-names (e.g. for symbolic icons)
* There's a new gtk_text_view_get_cursor_locations() to enable
* The application chooser widgets can now set a custom
* The file chooser and application chooser widgets have received
minor visual improvements
* gtk-auto-mnemonics is now backed by an XSetting
* Defaults for GtkSettings, as well as theme-specific settings,
are now read from key files
* Key themes are now supported again, their syntax has been changed
to be CSS-like
* More objects use GtkStyleContext directly now:
* GtkPlug and GtkSocket have been reduced to X11-specific API, and
using them requires including the <gtk/gtkx.h> header, and uses
of GdkNativeWindow in their APIs have been replaced by the X11
A number of other API changes were necessary in GDK to ensure
that multiple GDK backends can coexist:
- GdkNativeWindow has been dropped
- The GdkEventOwnerChange owner field is a GdkWindow now
- The GdkEventSelection requestor field is a GdkWindow now
- The GtkWidget::client_event vfunc is gone
- GdkEventClient is gone, together with related API:
- gdk_drag_get_protocol_for_display has been changed to
* Migration guide and tutorial and other documentation improvements
* Bug fixes
