    KDE Project Ships First Beta Release for Leading Free Software Desktop,
                               Codename "Cnuth"

KDE 4.0 Beta 1 marks the stabilizing of foundations for the new major release
of KDE.

August 2, 2007 (The INTERNET). The KDE Community is happy to announce the
immediate availability of the first Beta release for KDE 4.0. This release
marks the beginning of the integration process which will bring the powerful
new technologies included in the now frozen KDE 4 libraries to the
applications.

Almost two months after the foundations of KDE 4 have been laid with the first
alpha, KDE enters the stage of a full freeze of the library interface. From 
now
on, the applications will focus on integrating the new technology refined
during the last months, and the library developers will try to fix all bugs
found during this process. No new applications will enter the official KDE
modules and usability and accessibility work is of course an ongoing process.
In the following weeks KDE developers will be able to add features to their
applications until the next beta is released and the application features will
be frozen as well.

Current status

At this moment, the codebase is still moving quickly. The new foundations are
stabilizing, but applications are still in flux. Since the last Alpha, a lot 
of
work has been committed. We've seen improvements all over KDE again. In the
following sections we will try to highlight a few of them.


Architectural

Marble is an application showing a spherical earth which you can zoom and
rotate. Marble is a geographical application and widget and it is compatible
with Google Earth's KMZ files), but more lightweight. Marble uses Wikipedia 
for
retrieval of geographical data and offers easy downloading of new maps, views
and other data. Inspite of using a combination of vector and bitmap data, it 
is
not slow, even without hardware accelleration in the form of OpenGL. Google
sponsors three students working on Marble through their Summer of Code 
project.
Marble also doubles as a generic geographical map widget and framework. It 
will
allow developers to easily show a person's location or let the user choose a
timezone by embedding it into their application. Of course, the educational
applications and the games will make use of this.

On July the 20th, the Icon/ Pixmap Cache was merged by Rivo Laks into the KDE
libraries. The icon cache speeds up loading icons when starting applications,
and in the future, it might contribute to performance when using fully 
scalable
icons and other scalable interface elements. The pixmap cache makes caching of
images rendered by the application, such as from SVG files, easy for
application developers. The result will be improved startup and (to a lesser
extent) runtime performance, already seen in the games KMines and KLines.

Applications

Slowly, the many changes to the foundation of KDE are starting to become
visible to the users. Applications are starting to capitalize on the new
architecture, while adding features and other improvements.

Since the previous report on KWin, the KDE window manager, a lot progress has
been made. Most work has gone into new and improved effects and their
configuration dialogs. Users of low-end hardware aren't forgotten, as KWin 
will
now automatically fallback to XRENDER or or even disable compositing in the
absence of OpenGL rendering.
Further, Integration between Dolphin the filemanager in KDE and Konqueror,
KDE's webbrowser has been improved, and Gwenview, the image viewer received
usability work and features.

In addition to lots of user interface cleanups and improvements, Konsole has
improved automatic tab titles, support for random background colors per-tab,
clickable URLs and a new default color scheme. Konsole now also provides hints
to the terminal about the color scheme being used to allow programs such as 
Vim
to adapt their palette accordingly, improving readability for the user.

Okular, the universal document viewer of KDE4 introduces usability
improvements, better multithreading and work on the print preview component.

System administrators will be happy to hear KRDC, our remote desktop tool, has
been adopted by Urs Wolfer. He is rewriting KRDC, solving many longstanding
issues and adding features like tabbed view and KWallet support. Work in
KDE-PIM is picking up, as features from the KDE-PIM Enterprise branch are
merged. KOrganizer received a gantt-based time line view and an Outlook-style
view, and KMail incorporated the tagging patches.

More effort went in KOrganizer's theming interface by Loïc Corbasson, who is
extending the theming and plugin interface and writing some example plugins
like a Wikipedia 'this day in history' one.

Next up

Now the KDE libraries are rather stable, the development focus is shifting to
finishing other components of the desktop. One of the most notable components
is Plasma. While the developers are pretty much ready with the infrastructure
for the plasmoids, most of them are not yet shipped by default Development of
those features is happening in KDE's source code repository in the playground
module. Thus, you will still see good old Kicker, KDE's panel and taskbar when
you boot up KDE 4.0 Beta 1.
Javascript support has been added to plasma, and according to its lead
developer we might soon support the Mac OS X Dashboard widgets. Superkaramba
applets are supported already, Opera widgets might follow soon.

Porting

Extragear applications like DigiKam and KPhotoalbum are busy porting to KDE 4,
and we encourage all application authors who haven't started this yet to get
going with the porting guide.

Get it, run it, test it...

For those interested in getting packages to test and contribute, several
distributions notified us that they will have KDE 4.0 Beta 1 packages 
available
at or soon after the release. The new Ark Linux 2007.1 release can be expected
any day now, and they will have Beta1 packages available soon after that. 
Then,
their development tree will also switch to KDE 4 as its primary desktop.
Likewise, Mepis Linux plans to have KDE 4 beta 1 packages available with their
upcoming 7.0 release. As usual, Kubuntu packages are available, and openSUSE
also offers KDE 4.0 Beta 1 to its users - additionally in the form of KDE Four
Live, a livecd.

KOffice Releases Second Alpha

Along with KDE 4.0 Beta 1, KOffice releases its second alpha version. This
version is released as a technology preview to let the public catch a gleam of
what is coming in KOffice version 2.0. It does not have the same level of
maturity as the rest of KDE 4.0 Beta 1.


KWord, a KOffice application using Flakes of various types

The infrastructural changes are enormous. KOffice version 2 series will take
full advantage of the improved Qt 4, giving it new features like text
directionality and improved layouting. The text rendering is also much
improved, giving it a professional quality text layout if the fonts support 
it.

The core of the new improvements is the revolutionary Flake library which will
allow KOffice to use any shape in any application. A Flake shape can be
something as simple as a circle or something as complex as a complete
spreadsheet. It is also extremely simple to create new shapes, something that
is demonstrated by the Google-sponsored Summer of Code project Music Notation
flake, in which a student creates a music notation plugin in just 6 weeks.

Although KOffice is included in KDE 4.0 Beta 1, it has its own release cycle,
and the first version of the KOffice version 2 series is expected around the
new year 2007-2008

About KDE

KDE is an award-winning, independent project of hundreds of developers,
translators, artists and other professionals worldwide collaborating over the
Internet to create and freely distribute a sophisticated, customizable and
stable desktop and office environment employing a flexible, component-based,
network-transparent architecture and offering an outstanding development
platform.

The KDE 3 branch continues to provide a stable, mature desktop including a
state-of-the-art browser (Konqueror), a personal information management suite 
(
Kontact), a full office suite (KOffice), a large set of networking application
and utilities, and an efficient, intuitive development environment featuring
the excellent IDE KDevelop.

KDE is working proof that the Open Source "Bazaar-style" software development
model can yield first-rate technologies on par with and superior to even the
most complex commercial software.
