+
+General Improvements
+--------------------
+
+- Legal
+ * This version introduces the GPL version 3 as an alternative
+ license for the Open Source Edition of Qt, in addition to the
+ existing licenses.
+ * Updated the GPL Exception to version 1.2, which grants additional
+ rights to developers using the LGPL version 3.0 and other licenses
+ for their software.
+
+- Configuration/Compilation
+ * [102113, 151125] Make it possible to use Qt headers with MSVC's
+ warning level 4.
+ * [129841] Make Qt compile with Intel C++ 9.0 and Intel C++ 10 compilers
+ on Windows.
+ * [168868] Add experimental support for the Blackfin processor.
+ * [188167] Fixed a bug in the solaris-cc mkspec that would cause
+ it to always use RPATH, even when configured with -no-rpath.
+ * [176029] Added qmalloc.cpp with qMalloc() and qFree() implementation
+ to make it easier to replace the default container allocators with
+ custom allocators (by providing your own qmalloc.o(bj) file).
+ * Enable -reduce-exports automatically on linux-icc* mkspecs when
+ using version 10.1 of the Intel C++ Compiler for Linux.
+ * Add experimental support for the AVR32 processor.
+ * Allow building Qt with -release and the Intel C++ Compiler for
+ Linux. This required working around several compiler bugs by
+ turning optimizations off for certain modules. See the compiler
+ notes for more details.
+ * Add support for MSVC 2008, and add separate mkspecs for MSVC 2002 &
+ 2003.
+ * [189185] Avoid quoting the the include and library paths for iconv.
+
+- Documentation and Examples
+ * The Qt Designer Manual was updated to include new Qt Designer features.
+ * QtScript module overview was updated with more examples and reference
+ material.
+ * [161404] The 40000 Chips demo no longer shifts when clicking the OpenGL
+ button.
+ * [188676] Fixed text item moving in Diagram Scene example.
+ * New demo: Embedded Dialogs
+ * New demo: Browser
+ * New example: Graphics View / Pad Navigator
+ * New example: Item Views / Address Book
+ * New example: WebKit / Previewer
+ * New Example: XmlPatterns / Recipes
+ * New tutorial: Address Book
+ * Multiple bug fixes for the Torrent Client example.
+ * Speed-ups in the Ported Asteroids Example.
+ * [164223] All examples that use resources now include
+ Q_INIT_RESOURCES to avoid breakage in static builds.
+
+- Translations
+ * Added a Traditional Chinese translation of the Qt and tools courtesy
+ of Franklin.
+ * Added a Spanish translation of Qt courtesy of Enrique Matias Sanchez.
+
+- Signals and slots
+ * [147681] Added support for 'long long' and 'unsigned long long'
+ in queued connections.
+ * [125987] Optimized QMetaObject::activate(), the function that
+ actually delivers signals to all connected slots.
+ * [164558] Fixed a bug that caused queued signals to be delivered out
+ of order (not in the order they are emitted).
+ * [169554] Added Q_EMIT, to correspond to Q_SIGNAL and Q_SLOT.
+
+- Multithreaded painting
+ * [66358, 142031] Added support for painting on QImage, QPicture,
+ and QPrinter in multiple threads. See the Multithreaded
+ Programming documentation for more details on supported features
+ and known limitations.
+
+- Embedded QWidget support for Graphics View
+ * [177204] Added support for using layouts, styles, palettes and fonts,
+ as well as embedding QWidgets into a QGraphicsScene.
+
+- XML support in QtCore
+ * The QXmlStreamReader, QXmlStreamWriter and supporting classes
+ have moved from the QtXml module to the QtCore module. This change is
+ both source- and binary-compatible with previous versions. New
+ applications can opt to not link to QtXml when using these classes.
+
+- Printing
+ Made a number of improvements to printing in Qt 4.4, including
+ support for setting custom page sizes and custom margins as well as
+ the ability to programatically enumerate printers via the new
+ QPrinterInfo class. A couple of new classes, QPrintPreviewWidget
+ and QPrintPreviewDialog, have been added to make it easy to add a
+ print preview to an application. The QPrintDialog and QPageSetupDialog
+ for X11 have been redesigned and are hopefully easier to use.
+
+New features
+------------
+
+- XQuery 1.0 and XPath 2.0 support provided through the new QtXmlPatterns
+ module.
+
+- Qt Help module for embedding documentation into applications.
+
+- QSystemSemaphore provides a general counting system semaphore.
+
+- QSharedMemory provides access to a shared memory segment between multiple
+ threads and processes.
+
+- QLocalServer class provides a local socket-based server with a matching
+ new QLocalSocket class.
+
+- QFileSystemModel provides a data model for the local file system. Unlike
+ QDirModel, QFileSystemModel will fetch directory listings in a background
+ thread to prevent any locking in the GUI. QFileSystemModel is also much
+ faster and has a few more features then QDirModel.
+
+- QCommandLinkButton to support Vista style command links on all platforms.
+
+- QFormLayout provides a layout designed for convenient form creation with
+ the appropriate appearance on different platforms. This class previously
+ appeared in Qtopia/4.3, but has been integrated into Qt.
+
+- QtConcurrent provides a high level multi-threading API.
+
+- QPlainTextEdit provides a highly scalable plain text editor. It uses
+ similar technology and concepts as QTextEdit, but is optimized for plain
+ text handling; e.g. as a log viewer.
+
+- QTextBoundaryFinder is a new class implementing the Unicode text
+ boundaries specification.
+
+
+Third party components
+----------------------
+
+- Updated Qt's SQLite version to 3.5.4.
+
+- Updated Qt's libpng version to 1.2.25.
+
+- Added CLucene version 0.9.17.
+
+- Added WebKit (see the src/3rdparty/webkit/VERSION file for the version).
+
+- Added Phonon version 4.1.

+ QGraphicsScene implementation.
+
+- QGraphicsSceneHoverEvent

+ of its check box.
+ * Don't call updateGeometry() needlessly from resizeEvent().
+
+- QHash
+ * [171909] Don't rehash in operator[] and insert() when the key already
+ exists -- to avoid subtle bugs when iterating on a QHash. (This is

+ print warnings if it was used before QCoreApplication is created
+
+- QHttpHeaders

+ while process is still running." when using Cleanlooks.
+ * [155704] Fixed a bug where widgets with MSWindowsFixedSizeDialogHint
+ flag would be minimized when their parent QMainWindow was minimized.
+ The MSWindowsFixedSizeDialogHint is now ignored on X11.
+ * [153155] Make it possible to bypass g_thread_init() and have the
+ Unix event dispatcher be used in threads instead by setting the

+ * [187752] Fixed a bug where calling show() and hide() on a window
+ before the event loop starts would prevent the window from ever
+ being shown.
+ * [189045] Reset the keyboard and mouse grabs to the current
+ grabber when the last popup is closed.
+ * [167707] Add support for all known _NET_WM_WINDOW_TYPE_* types

+ is not necessary).
+ * [192871] Fixed a regression found in the 4.4.0 snapshots that

+ _MOTIF_DRAG_WINDOW property is missing.
+ * [183477] Fixed a bug that would cause a window to disappear
+ after restoring it with QWidget::restoreGeometry().
+ * [163507] Fixed a couple of memory errors reported by valgrind.

+ text/uri-list mime type) between applications.
+ * [198709] Fix QDesktopWidget to not report overlapping screens on
+ servers with Xrandr 1.2.
+ * [146336] On UNIX systems without CUPS support, the
+ $HOME/.printers is now checked for a default printer.
+ * [185864] Allow Qt to find the OpenSSL libraries dynamically even
+ if the libssl.so file is not present.

+****************************************************************************
+* Plugins *
+****************************************************************************
+
+- QTiffPlugin

+

+ The qsvg icon engine plugin has been renamed to qsvgicon to disambiguate

+ QIcon for different modes.
+ * Streaming of SVG icons is fixed.
+
+****************************************************************************
+* Important Behavior Changes *
+****************************************************************************
+
+- Event filters
+
+ The behavior of event filters has changed starting with
+ 4.4. Previously, thread affinity was ignored when adding,
+ removing, and activating an object's event filters. Now, event
+ filters must have the same thread affinity as the object they
+ are filtering. Qt will warn when it detects a filter that is
+ in a different thread from the object being filtered.
+
+- QFont
+ Starting with Qt 4.4, the '-' characters in the raw font names
+ are no longer substituted with a ' ' (space character). This
+ may impact your application if you use fonts that have '-'
+ characters in their raw font names.
+
+- QReadWriteLock
+ Starting with Qt 4.4, recursive lock support is disabled by
+ default in QReadWriteLock. Code that relies on recursive write
+ locking will need to be changed to construct the
+ QReadWriteLock with recursive lock support enabled. Previously,
+ recursive write-lock support (introduced in 4.3) was enabled by
+ default, but QReadWriteLock did not properly support recursive
+ read-lock support. QReadWriteLock now supports both and needs to
+ be constructed explicitly with recurive lock support enabled
+ (QMutex works in the same way).
+
+- QPainterPath
+ We have changed QPainterPath::angleAtPercent() to use the same
+ angle definition as in the rest of Qt. This means that the angle
+ returned will be from 0 to but not including 360, specifying
+ the degrees from the 3 o'clock position in the counter-clockwise
+ direction.
+
+- QDirectPainter [Qt for Embedded Linux-specific class]
+ startPainting() in Qt 4.3 had a default parameter lock=false,
+ the value of which was not used. The function would lock for
+ client processes, but not for the server process. From Qt 4.4,
+ the default value is changed to true, and startPainting() will
+ lock if lock == true, and not lock if lock == false. This means
+ that client processes running code that has not been recompiled
+ with Qt 4.4 may show flicker and/or painting problems. To get
+ exactly the same behaviour as for Qt 4.3, change startPainting()
+ to startPainting(QApplication::type() == QApplication::GuiClient).
+
+- QPrinter
+ QPrinter::pageRect() did not return consistent values on
+ Linux/Mac/Windows when QPrinter::fullPage() was set to true. On
+ Mac and Windows pageRect() was not influenced by the fullPage()
+ setting. This has now been changed so that pageRect() returns
+ the same as paperRect() when fullPage() is true on all
+ platforms.
+
+- QPixmap
+ Using QPixmap outside of the GUI thread is dangerous and error
+ prone. Because of this, starting with 4.4, any QPixmap created

+- QDateTime
+ When using QDateTime::fromString() to parse dates, QDateTime
+ no longer tries to use English month names because that would
+ cause some dates to become unparseable. If you need to parse
+ date times in the English locale, use QLocale::toDateTime (in
+ specific, the QLocale::c() locale).
+
+- Qt/Mac
+ Starting a Qt application no longer makes it the front process. This is
+ more in-line with other applications on Mac OS X. What this means is
+ that you can start a Qt application, do something else and not have the
+ Qt application steal your focus. If you desire for the Qt application
+ to become the front process, you can call QWidget::raise()
+ programmatically or launch the application with open(1) or using
+ QDesktopServices. This should not have any affect if launched from
+ double-clicking in Finder or run in a debugger.
+
+- Qt/X11 on MIPS Linux
+ qreal is changed from float to double, breaking binary compatibility.
+ This change fixes a bug introduced in Qt 4.3.0 when qreal was
+ changed from double to float for embedded MIPS processors.
