That’s the moment we’ve all been waiting for… or dreading. We’ve worked for long months getting it done and you’ve all been asking for it. Some of you even realised it has already been available for a few days, unannounced… And now it’s finally, at last, there!
Last week, we had a sneak release to current customers. And now it’s on the Trolltech homepage for the world to see. To make your life easier, here’s a download button:
We’re quite proud of this release. It’s the most feature-packed release of Qt ever and certainly the largest release since Qt 4.0.0 itself. This release adds:
- The Windows CE platform
- The Phonon new module: multimedia integration
- The QtWebKit new module: web integration
- The QtXmlPatterns new module: powerful XML support
- The QtHelp new module: flexible help support
- The QtConcurrent framework: parallel programming
- A new network resource access stack
- Support for regular widgets on Graphics View
- Support for non-native windows
- Support for shared memory
- Support for inter-process semaphores
- Support for painting on auxiliary threads
- Support for atomic operations on integers and pointers
- Improved printing support
- A new Qt Assistant
- And much more, since I will never be able to remember everything we’ve done
Not happy with all of that, we’re also bringing you:
- A video showing our demos
- A downloadable version of the pre-built demos (Windows only)
- White papers on embedded development, web support, XML, user interface styling
Continuing with the tradition started with the past minor release, we bring you those who did the work:

The Italian, it’s The Italian! 
@danimo: Bingo!
@Simon: Ooops, sorry for hiding you…
Great job guys and gals! Can’t wait to see how KDE people will take adventage of all the nice features in Qt 4.4. BTW the news about Qt 4.4 is already on Digg: http://digg.com/programming/Qt_4_4_Framework_Broadens_Rich_Application_Development and goodness is ready to spread
Please fix the file on server for debug libraries of open source edition for Mac - it links to commercial edition (thus requiring to type a license key). The offending file is at ftp://ftp.trolltech.com/qt/source/qt-mac-opensource-4.4.0-debug-libs.dmg . Thanks
This is one helluva great release, awesome job guys Two of my features: New delegate for item views (QStyledItemDelegate) and new Style Sheet features like Customizable icons, styling dock widgets.
BTW, it was supremely painful to register for 4 times for the white papers! May be a “give it all to me” link 
?
And look what Qt Embedded for both Windows CE/Mobile and Linux (Framebuffer) can do: http://dist.trolltech.com/video/wince/qtembedded44video.html
If you are watching anyway, don’t miss the demo of Qt/Embedded on Linux and Windows CE/Mobile: http://dist.trolltech.com/video/wince/qtembedded44video.html
I love Qt . It’s the greatest toolkit I know and with Qt 4.4 I love it always more .
@asdfhjkl: You’re missing the G key in your nickname
You’re right, the debug-libs package for Mac is incorrect. The MD5 checksum of the file currently on FTP matches the commercial debug-libs.dmg file I created. We’ll fix this soon. (FTP update isn’t instantaneous)
The phonon music player in the examples won’t launch. says “Could not launch the example. Ensure that it has been built”. Using win xp sp2.
Downloaded the demo app but when I installed it none of the text is readable.

Guys, blogs are not bug-reporting tools.
Good work ! It was really a customer delight release…
I could build without trouble.
Wish you all better wealth with Nokia offer
Congrats to you all. Great job.
Great release and some nice new features!
But still some problems with static builds.
Concerning the bug with VS9 + Feature Pack: This is not the fault of Trolltech,
but of Microsoft, or more exactly of P.J. Plauger.
To resolve, remove the line “#include ” from C:\qt\4.4.0\src\3rdparty\webkit\JavaScriptCore\wtf\MathExtras.h.
For the interested: The header file “xmath.h” does a “#define _F0 1″, and the file “xrefwrap”
(included later) uses the name _F0 as a parameter in some templates.
Took me some time to hunt that one down.
Indeed, the best framework design I have ever encountered in 20 years of programming. Now for next version, I wish something like (not virtual)…
Qt4_5->ensurePolished();
Congratulations! Especially with all the “background” distractions a very impressive release!
