++ *                           General                                        *

++

++ 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.

++

++ - QHeaderView

++     * [173773] QHeaderView now updates properly upon sorting a column.

++     * [192884] When the model emits layout changed unhide old hidden rows

++       and QImage::Format_RGB888.

++     * Added support for the ICO image format (from Qt Solutions)

++     * Fix drawing of text into a QImage on the Mac so that the native

++

++ - QLibrary

++     * [190831] Fixed crash when calling loadHints on a default constructed

++       QLibrary.

++     * [155109] The real error message was discarded if the library existed,

++       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

++       QT_NO_THREADED_GLIB environment variable.

++     * [157807] Fix an inefficiency in the Glib dispatcher's

++       timerSourcePrepare() implementation.

++     * [158332] Fix a bug where text/uri-list drops from Qt 3 would

++       sometimes report the wrong state.

++     * [173328] Fixed QEventLoop::exec(ExcludeUserInputEvents) to not

++     * [179536] Make QEventLoop::X11ExcludeTimers work as expected with

++       the Glib event dispatcher.

++     * [182913] Qt will now always look for the _MOTIF_DRAG_WINDOW

++       property on screen 0 (instead of the default screen).

++     * [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.

++       grabber when the last popup is closed.

++     * [167707] Add support for all known _NET_WM_WINDOW_TYPE_* types

++     * [194566] Fixed a bug found in the 4.4.0 snapshots that would

++       always cause the cursor to change when QWidget::setCursor() was

++       called on a widget that was not under the mouse.

++     * [173746] Fixed a bug in QDialog that would cause the "What's

++       This?" popup menu to appear on the wrong X11 screen.

++     * [187965] Fixed a bug where moving a widget that is hidden could

++       cause the positioning to be incorrect.

++     * [160206] Fixed some bugs in QX11EmbedWidget and

++       QX11EmbedContainer to provide minimal support for multiple

++       containers and multiple embedded widgets in the same

++       application.

++       after restoring it with QWidget::restoreGeometry().

++     * [163507] Fixed a couple of memory errors reported by valgrind.

++       under X11.

++     * [176485] Make drawing text through FreeType beyond the SHORT_MIN/MAX

++       coordinate range work. Note that this won't work for XLFD based fonts.

++     * Redesigned the print dialog and pagesetup dialog to be much nicer.

++

++ - QPrinter

++     * [148125] Switched to printing through the CUPS API. This should fix the

++       problem where the wrong lp/lpr command was picked up, and therefore

++       in a save dialog.

++     * [196062] HANDLEs are now freed when searching the paths.

++     * [198049] Selecting a file in the completer would display the full path rather then just the file name if it was in the current directory.

++

++ - QDesktopServices

++     * [194046] Fixed support for percentage encoded URL strings with openUrl().

++     * [172914] Fixed an issue where openUrl() would incorrectly return true

++       after failing to open on Windows.

++

++ - QFileSystemWatcher

++     * [170021] Make it possible to monitor FAT32 directories.

++

++ ****************************************************************************

++ *                   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.
