+Qt 4.2 introduces many new features as well as many improvements and
+bugfixes over the 4.1.x series. For more details, see the online
+documentation which is included in this distribution. The
+documentation is also available at http://qt.nokia.com/doc/
+The Qt version 4.2 series is binary compatible with the 4.1.x series.
+Applications compiled for 4.1 will continue to run with 4.2.
+The Qtopia Core version 4.2 series is binary compatible with the 4.1.x
+series except for some parts of the device handling API, as detailed
+in Platform Specific Changes below.

+*                           General                                        *
+****************************************************************************
+New features
+------------
+- QCalendarWidget provides a standard monthly calendar widget with date
+selection features.
+- QCleanlooksStyle provides the new Cleanlooks style, a clone of the GNOME
+ClearLooks style, giving Qt applications a native look on GNOME desktops.
+- QCompleter provides facilities for auto completion in text entry widgets.
+- QDataWidgetMapper can be used to make widgets data-aware by mapping them
+to sections of an item model.
+- QDesktopServices provides desktop integration features, such as support
+for opening URLs using system services.
+- QDialogButtonBox is used in dialogs to ensure that buttons are placed
+according to platform-specific style guidelines.
+- QFileSystemWatcher enables applications to monitor files and directories
+for changes.
+- QFontComboBox provides a standard font selection widget for document
+processing applications.
+- QGraphicsView and related classes provide the Graphics View framework, a
+replacement for Qt 3's canvas module that provides an improved API, enhanced
+rendering, and more responsive handling of large numbers of canvas items.
+- QGLFramebufferObject encapsulates OpenGL framebuffer objects.
+- QMacPasteboardMime handles Pasteboard access on Qt/Mac. This obsoletes
+QMacMime as the underlying system has changed to support Apple's new
+Pasteboard Manager. Any old QMacMime objects will not be used.
+- QNetworkInterface represents a network interface, providing information
+about the host's IP addresses and network interfaces.
+- QResource provides static functions that control resource lookup and
+provides a way to navigate resources directly without levels of
+indirection through QFile/QFileEngine.
+- QSystemTrayIcon allows applications to provide their own icon in the
+system tray.
+- QTimeLine gives developers access to a standard time line class with which
+to create widget animations.
+- The QtDBus module provides inter-process communication on platforms
+that support the D-BUS protocol.
+- The QUndo* classes in Qt's Undo framework provide undo/redo functionality
+for applications.
+- Support for the Glib event loop to enable integration between Qt and non-Qt
+applications on the GNOME desktop environment.
+- Improved Accessibility for item-based views and QTextEdit.
+- Support for main window animations and tabbed dock widgets.
+- Added an SVG icon engine to enable SVG drawings to be used by QIcon.
+- Widgets can now be styled according to rules specified in a style sheet,
+using a syntax familiar to users of Cascading Style Sheets (CSS). Style
+sheets are set using the QWidget::styleSheet property.
+- Introduced a new key mapper system which improves the shortcut system by
+only testing the real possible shortcuts, such as Ctrl+Shift+= and Ctrl++
+on an English keyboard.
+- Improved and enhanced QMessageBox to support native look and feel on many
+common platforms.
+- Experimental support for Qt usage reporting ("metered licenses") on Linux,
+Windows and Mac OS X. Reporting is disabled by default.
+- A screen magnification utility, pixeltool, is provided. It is designed to help
+with the process of fine-tuning styles and user interface features.
+- New qrand() and qsrand() functions to provide thread safe equivalents to
+rand() and srand().
+General improvements
+--------------------
+- Item views
+* Selections are maintained when the layout of the model changes
+(e.g., due to sorting).
+* Convenience views can perform dynamic sorting of items when the data
+in items changes.
+* QStandardItem provides an item-based API for use with
+QStandardItemModel and the model/view item view classes.
+* QStandardItemModel API provides a classic item-based approach to
+working with models.
+* Single selection item views on Mac OS X cannot change their current
+item without changing the current selection when using keyboard
+navigation.
+- Plastique style has improved support for palettes, and now requires
+XRender support on X11 for alpha transparency.
+- Tulip containers
+* Added typedefs for STL compatability.
+* Added function overloads to make the API easier to use.
+- Added the Q3TextStream class for compatiblity with Qt 3 and to assist with
+porting projects.
+- OpenGL paint engine
+* Added support for all composition modes of QPainter natively using
+OpenGL.
+* Fixed a case where very large polygons failed to render correctly.
+* Ensured that glClear() is only called in begin() if the
+QGLWidget::autoFillBackground() property is true.
+* Ensured that a buffer swap is only performed in end() if
+QGLWidget::autoBufferSwap() is true.
+* Improved text drawing speed and quality.
+- Raster paint engine
+* Fixed blending of 8 bit indexed images with alpha values.
+* Fixed drawing onto QImages that were wider than 2048 pixels.
+* Fixed alpha-blending and anti-aliasing on ARGB32 images.
+* Improved point drawing performance.
+* Fixed issue where lines were drawn between coordinates that were
+rounded instead of truncated.
+* Ensured that setClipRegion(QRegion()) clips away all painting
+operations as originally intended.
+Third party components
+----------------------
+- Dropped support for MySQL version 3.
+- Updated Qt's SQLite version to 3.3.6.
+- Updated Qt's FreeType version to 2.2.1.
+- Updated Qt's libpng version to 1.2.10.
+Build System
+------------
+- Auto-detect PostgreSQL and MySQL using pg_config and mysql_config on UNIX
+based systems in the configure script
+- Added "-system-sqlite" option to configure to use the system's SQLite
+library instead of Qt's SQLite version.
+- Added QT_ASCII_CAST_WARNINGS define that will output a warning on implicit
+ascii to Unicode conversion when set. Only works if the compiler supports
+deprecated API warnings.
+- Added Q_REQUIRED_RESULT to some functions. This macro triggers a warning
+if the result of a function is discarded. Currently only supported by gcc.
+- Qt/X11, Qt/Mac and Qtopia Core only:
+* Added all QT_NO_* defines to the build key.
+- Qt/X11 and Qtopia Core only:
+* As in Qt 3, the configure script enables the -release option by
+default, causing the Qt libraries to be built with optimizations. If
+configured with the -debug option, the debug builds no longer result
+in libraries with the _debug suffix.
+On modern systems, flags are added to the Qt build to also
+generate debugging information, which is then stored in a
+separate .debug file. The additional debug information does not
+affect the performance of the optimized code and tools like gdb
+and valgrind automatically pick up the separate .debug
+files. This way it is possible to get useful backtraces even
+with release builds of Qt.
+* Removed the last vestiges of the module options in the configure
+script, previously they were available but did not function.
+* Implemented a -build option in the configure script to conditionally
+compile only certain sections of Qt.
+* Made it possible to build Qt while having "xcode" set as your
+QMAKESPEC on OSX.
+- Windows only:
+* Populated the build key, as done on all the other platforms.
+* Fixed dependency generation in Visual Studio Solutions (.sln)
+created by qmake.
+* Added missing platforms to the Visual Studio project generator (X64,
+SH3DSP and EBC).
+* Made UIC3 use a temporary file for long command lines.
+* Removed the object file (.o) conflicts with MinGW that appeared when
+embedding a native resource file which was named the same as a normal
+source file.
+* Fixed mkspec detection when generating project files outside of QTDIR.
+* Removed compiler warnings with MinGW g++ 3.4.5.
+****************************************************************************
+*                          Library                                         *
+****************************************************************************
+- QAbstractButton

+backgroundRole() and foregroundRole(), respectively, rather than
+QPalette::Background and QPalette::Foreground.

+rectangle.
+* Fixed regression for shift-selections in ExtendedSelection for
+all views.
+* Added dragDropMode property and implemented move support in all of
+the views and models.
+* For edit triggers SelectedClicked and DoubleClicked, only trigger
+editing when the left button is clicked.
+* Trigger SelectedClicked editing on mouse release, not mouse press.
+* Suppressed the doubleClicked() signal in cases where the clicks
+happened on two different items.
+* Enabled keyboard search to be programmatically reset by calling
+keyboardSearch() with an empty string as argument.
+* Don't allow drops on items that don't have the Qt::ItemIsDropEnabled

+management in an application.
+* Added the styleSheet property to get/set the application style sheet.
+* Support sending key events to non-widget objects.

+* Added support for the newly added Qt::OpenHandCursor and
+Qt::ClosedHandCursor enum values.

+even though the result is documented to be undefined.
+* Fixed maximum size handling when adding spacing.
+- QGroupBox
+* Activating a group box by a shortcut will now show the focus rectangle.
+* Added the clicked() signal
+- QHash
+* Prevent conversion of iterator or const_iterator to bool
+(e.g., if (map->find(value))) because the conversion always returned
+true. Qt 4.1 code that doesn't compile because of this change was most
+probably buggy.
+* Added the uniqueKeys() function.
+- QHeaderView
+* Use the current resize mode to determine section sizes when
+new rows are inserted.
+* Recover the internal state if other widgets steal the mouse release
+event.
+* Ensure that moved sections can be removed without asserting.

+* Improved reading performance significantly by using an internal buffer
+when a device is opened in buffered mode.
+* Some behavioral differences have been introduced:
++ The following functions now need to call the base implementation
+when reimplemented: atEnd(), bytesAvailable(), size(), canReadLine().
++ pos() should return the base implementation directly.
++ QIODevice now handles the device position internally. seek() should
+always end up calling the base implementation.
+- QItemDelegate
+* Use a widget's USER property to set and get the editor data.
+* Removed unnecessary assertions.
+* Added the clipping property to enable clipping when painting.
+* When the model specifies a font, resolve the font over the existing
+one rather than replacing it.
+* Fixed issue with rendering of selected pixmaps.
+* Ensured that QItemEditorFactory is called with the variant's
+userType() so that the factory can distinguish between multiple user
+types.
+* Ensured that Key_Enter is propagated to the editor before data is
+committed, so that the editor has a chance to perform custom input
+validation/fixup.
+* Let the line edit grow to accomodate long strings.
+* Made it easer to subclass the item delegate.
+* Added support for keypad navigation.
+- QItemSelectionModel

+* Ensure that QAbstractItemView::clearSelection() only clears the
+selection and not the current index.
+* Added the hasSelection() function.
+* Fixed some connection leaks (connections were not disconnected) when
+an QItemSelectionModel was deleted. This should also speed up some
+special cases.

+console.
+* Increased the number of acceptable file name suffixes used to
+recognize library files.
+- QLineEdit
+* Ensured that the Unicode context menu gets shown if language
+extensions are present.
+* Ensured that editingFinished() is not emitted if a validator is set
+and the text cannot be validated.
+* Ctrl+A now triggers select all on all platforms.
+* Call fixup on focusOut() if !hasAcceptableInput().

+an area with several items are stacked on top of each other.
+* Optimized hiding and showing of items.
+* Fixed issue where dragging an item in Snap mode did not respect the
+scroll bar offsets.
+* Fixed issue in Snap mode where a (drag and) drop did not always
+query the item that existed in the corresponding cell for an enabled
+Qt::ItemIsDropEnabled flag.
+- QListWidget/QTreeWidget/QTableWidget
+* Ensured the dataChanged() signal is emitted when flags are set on an
+item.

+them to fail on negative numbers which contained thousand-
+separators.
+* Implemented the numberOptions property for specifying how
+string-to-number and number-to-string conversions should be
+performed.
+- QMainWindow
+* Added support for tabbed dock widgets.
+* Enhanced look and feel of dock widget handling. When a dock widget
+hovers over a main window, the main window animates the existing
+dock widgets and main area to show how it will accept the dock
+widget if dropped.
+* Fixed issues related to insertToolBarBreak().
+- QMap
+* Prevent conversion of iterator or const_iterator to bool
+(e.g., if (map->find(value))), because the conversion always
+returned true. Qt 4.1 code that doesn't compile because of this
+change was most probably buggy.
+* Added the uniqueKeys() function.
+- QMenu
+* Added the aboutToHide() signal.
+* Added the isEmpty() accessor function.
+* Clear menuAction() when setMenu(0)
+* Added support for widgets in menus via QWidgetAction.

+* Added the userProperty() and normalizedType() functions.
+- QMetaType
+* Ensured that all type names are normalized before registering them.
+* Added support for handling Qt's integer typedefs: qint8, qint16,
+etc.
+- QModelIndex
+* Added the flags() convenience function.
+- QMutexLocker, QReadLocker, and QWriteLocker
+* These classes now track the state of the lock they are holding.
+They will not unlock on destruction if unlock() has been called.
+- QObject
+* thread() will always return a valid thread, even if the object was
+created before QApplication or in a non-QThread thread.
+* When thread() returns zero, events are no longer sent to the object.
+(Previous versions of Qt would send posted events to objects with no
+thread; this does not happen in Qt 4.2).
+* Added support for dynamically added properties via the new
+property(), setProperty(), and dynamicPropertyNames() functions.
+* Fixed a crash that could occur when a child deleted its sibling.
+- QPainter
+* Fixed a crash the occurred when drawing cosmetic lines outside the

+to load.
+- QPrinter
+* Added support for PostScript as an output format on all platforms.
+* Significantly reduced the size of the generated output when using
+the PostScript and PDF drivers.
+* Fixed issue where fromPage()/toPage() returned incorrect values when
+generating PDF files.
+* Ensured that setOutputFormat() preserves previously set printer
+properties.
+* Updated setOutputFileName() to automatically choose PostScript or
+PDF as the output format for .ps or .pdf suffixes.
+- QProcess
+* Added support for channel redirection to allow data to be redirected
+to files or between processes.
+- QPushButton
+* Ensured that, when a menu is added to a push button, its action is
+also added to enable keyboard shortcuts.
+- QRect, QRectF, QRegion
+* Renamed unite(), intersect(), subtract(), and eor() to united(),
+intersected(), subtracted(), and xored() respectively.
+* Added QRegion::intersects(QRegion) and QRegion::intersects(QRect).
+* Fixed case where rect1 & rect2 & rect3 would return a non-empty
+result for disjoint rectangles.
+- QRegExp
+* Added RegExp2 syntax, providing greedy quantifiers (+, *, etc.).
+* Marks (QChar::isMark()) are now treated as word characters,
+affecting the behavior of '\b', '\w', and '\W' for languages
+that use diacritic marks (e.g., Arabic).
+* Fix reentrancy issue with the regexp cache.
+- QScrollArea
+* Added the ensureWidgetVisible() function to facilitate scrolling to
