gtkmm 2.3.3
glibmm 2.3.4

gtkmm and glibmm 2.4:

NOTE: This is probably your last chance to comment on the API
before the API freeze. We plan no major changes apart from the use
of libsigc++ 2 very soon. In particular, we NEED access to a SUN
box running a recent Forte compiler.

gtkmm provides a C++ interface to GTK+. The 2.3.x tarballs are
the unstable development series that will become the stable gtkmm
2.4. gtkmm 2.3/2.4 will wrap any additional API in GTK+ 2.4. glibmm
is now a separate module, for use in non-GUI software.

gtkmm 2.3/2.4 installs in parallel with gtkmm 2.2, so you can
install this unstable library without the risk of breaking existing
applications. This allows us to break ABI and API, though we will
try not to break API unless it is absolutely necessary.

But do be aware that the underlying unstable GTK+ 2.3 does not
install in parallel with GTK+ 2.2, so be careful if you apply it in
your normal prefix.

We recommend the use of jhbuild or garnome for testing in a
separate prefix.

The stable (API/ABI-frozen) gtkmm 2.4.0 will be released soon
after GTK+ 2.4.0.
gtkmm is on the official GNOME Platform Bindings release schedule:

Changes

glibmm 2.3.4:

• ListHandle/SListHandle (intermediate container types):
  • Added a const_cast<> to allow lists of const
    elements.
• gmmproc: _WRAP_SIGNAL(): Added optional custom_c_callback
  parameter. (Murray Cumming)
• WIN32: Build fixes, mostly merged from the 2.2 branch. (Cedric
  Gustin)

gtkmm 2.3.3:

• CellLayout: signals take a C++ CellRenderer* instead of a C
  GtkCellRenderer*.
• Widget:
  • signal_dragdata_get and
    signalselection_get now use the C++ SelectionData type.
  • Methods now take C++ Gdk::Region& instead of C
    GdkRegion*.
• SelectionData: Added set() method overload with fewer
  parameters.
• TreeDragSource: The drag_get_data vfunc now uses the C++
  SelectionData type.
• TreeIter (TreeModel::iterator): Added operator–().
• Added const version of many ListHandle<> get_*() methods.
  (Murray Cumming)

GStreamer 0.7.4

Release notes for GStreamer 0.7.4 “Wooden Eels”

The GStreamer team is happy to announce a new release in the
0.7.x development series of the GStreamer streaming-media
framework. The goal of this release series is to stabilize towards
a 0.8 release series which will be part of the GNOME 2.6 releases
and hopefully eventually KDE 4.x.

The 0.7 series is a development series and is aimed at
developers. It is NOT API or ABI compatible with the stable 0.6.x
series or with other releases in the series. This means you can not
use this release to upgrade your current GStreamer installation and
expect your GStreamer applications to keep working without a
recompile. It is, however, parallel installable with the 0.6.x
series.

Features of this release

• Merged the new caps system
• Reworked pad negotiation
• Internationalized core and elements
• Reworked error notification with translated error messages and
  additional debug information for developer feedback
• Updated Dutch and French translations
• Reworked clocking
• Serialization of GstValue
• Documentation of GstCaps
• Poisoning of GstCaps
• Queues now flushed properly to fix seeking in playback
• Memleak fixes in core elements
• Largely rewritten Plugin Writer’s Guide
• Unversioned tools that wrap all present and future versioned
  tools to help packagers
• Portability fixes for Solaris and OSX
• Lots of bugfixes

Download

You find source releases of gstreamer in the [14]gstreamer
download directory.

GStreamer Homepage

More details can be found on the project’s website, [15]http://www.freedesktop.org/~gstreamer.

Support and Bugs

We use Gnome’s bugzilla for [16]bug reports and feature
requests.

Developers

CVS is hosted on cvs.freedesktop.org/. You can
[17]browse the gstreamer repository. All code is in CVS and can be
checked out from there. Interested developers of the core library,
plug-ins, and applications should subscribe to the gstreamer-devel
list. If there is sufficient interest we will create more lists as
necessary.

Applications

As mentioned there are some changes in API/ABI between the 0.6.x
and 0.7.x releases. Many applications will probably be source
compatible between 0.6.x. and 0.7.x however. [18]Rhythmbox and
[19]Sound Juicer for instance work very well when compiled on
0.7.x. GStreamer Player does not work across releases however, so
we will make a separate release of gst-player with the needed fixes
for it to work with 0.7.x. This release contains the core fixes we
were waiting for to port the player over so expect a gst-player
release in the near future.
