+*                           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.

+****************************************************************************
+
+
+- QAbstractButton

+        backgroundRole() and foregroundRole(), respectively, rather than
+        QPalette::Background and QPalette::Foreground.
+
+      * Ensured that nextCheckState() is called only when there is a state
+        change.
+
+- QAbstractItemModel
+
+      * When dropping rows only insert rows that were actually dropped, not
+        the continuous row count from first to last.

+        QAbstractItemView when starting a drag.
+
+      * When updating changed persistent indexes, ignore those that haven't
+        actually changed.
+
+      * Fixed endian issue with createIndex().

+        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
+        flag set.
+
+      * Added modelAboutToBeReset() and layoutAboutToBeChanged() signals.
+
+      * Suppressed assertion in dropMimeData() for cases where mimeTypes()
+        returns an empty list.
+
+      * Ensured consistent behavior of drag and drop when rootIndex() is a
+        valid model index.

+
+- QAbstractSpinBox
+
+      * Added a hasAcceptableInput() property.
+
+      * Ensured that fixup/validate are called for third party subclasses of
+        QAbstractSpinBox as well.
+
+      * Fixed geometry issues when toggling frames on and off for spinboxes.
+
+      * Added a property for correctionMode.
+
+      * Added a property for acceleration.
+
+- QAbstractPrintDialog
+
+      * Fixed handling of existing printer options so that storage of page

+        resizing the header section. This includes the stretchLastSection
+        property.
+
+      * Added the minimumSectionSize property.
+
+      * Get the section size hint from the Qt::SizeHintRole, if set.
+
+      * Added the ResizeToContents resize mode.
+
+      * Ensure that all header contents are centered by default.
+
+      * Improved the internal structure to be more memory efficient.

+
+      * Fixed improper pixmap caching
+
+      * Added QDataStream operators for QIcon.
+

+      * Added support for faster/better rotation of images by 90/180/270
+        degrees.
+
+      * convertToFormat() now supports the color lookup table.
+
+      * Improved algorithm for smooth scaling to produce better results.
+
+- QImageReader
+
+      * Ensured that size() returns an invalid QSize if the image I/O handler
+        does not support the QImageIOHandler::Size extension.
+
+      * Added support for reading negative BMP images.
+
+      * Improved handling of invalid devices.
+
+      * Added optimizations to ensure that the most likely formats and plugins
+        are tested first when reading unknown image formats.
+
+      * Improved reading of BMP images from sequential QIODevices.
+
+      * Support for scaledSize() with JPEG images.
+
+      * It is now possible to query the supported options of an image by
+        calling supportedOptions().
+
+      * Stability fixes for the built-in XBM reader.
+
+- QImageWriter
+
+      * Ensured that an error is reported when attempting to write an image
+        to a non-writable device.
+
+      * It is now possible to query the supported options of an image by
+        calling supportedOptions().
+
+- QIODevice
+
+      * Fixed a casting bug in QIODevice::getChar().
+
+      * 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
+
+      * Improved overall speed, particularly when isSelected() is used.
+
+      * Added functions for getting the selected rows or columns.
+
+      * Ensured that the current index is updated when it is being removed.
+
+      * 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.
+
+- QKeySequence
+
+      * Added a set of platform-dependent standard shortcuts.
+
+      * Fixed incorrect parsing of translated modifiers.
+

+        systems.
+
+      * Added errorString() to report the causes of errors when libraries
+        fail to load.
+
+      * Added easier way to debug plugin loading: Setting QT_DEBUG_PLUGINS=1
+        in the environment will enable debug message printing on the
+        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().
+
+      * Added auto-completion support with the setCompleter() function.
+
+      * Fixed painting errors when contents margins were set.
+
+      * Invalid text set using setText() can now be edited where previously
+        it had to be deleted before new text could be inserted.
+
+      * Use SE_LineEditContents to control the contents rect of each
+        QLineEdit.
+
+- QListView
+
+      * Added the batchSize property.
+
+      * Don't un-hide currently hidden rows when new rows are inserted.
+
+      * Fixed partial repainting bug that occurred when alternatingRowColors
+        was enabled.
+
+      * Ensured that the resize mode is not reset in setViewMode() if it was
+        already set.
+
+      * Fixed crash that occurred when the first item was hidden and
+        uniformItemSizes was set.
+
+      * Added the wordWrap property for wrapping item text.
+
+      * Allow the user to select items consecutively when shift-selecting.
+
+      * Ensured that only the top item is selected when the user clicks on
+        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.
+
+      * Removed unnecessary assertions.
+
+      * Added more convenience functions in QListWidget, QTableWidget and
+        QTreeWidget for selecting, hiding, showing, expanding and collapsing
+        nodes.
+
+      * Ensured that changes to items are reported.
+
+- QLocale
+
+      * Fixed bug in the string-to-number functions which sometimes caused
+        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.

+      * Collapse multiple consecutive separators. This can be turned off
+        with the collapsibleSeparators property.
+
+      * Made scrollable menus wrap, just like non-scrollable ones.
+
+- QMessageBox
+
+      * Updated the API to allow more than 3 buttons to be used.
+
+      * Added support to display buttons in the order required by
+        platform-specific style guidelines.
+
+      * Added support for display of informative text using the
+        informativeText property.
+
+      * Added the detailedText property to allow detailed text to be
+        displayed.
+
+      * Improved sizing of message box (especially on Mac OS X).
+
+      * Changed the behavior so that long text strings are automatically
+        wrapped.
+
+      * Updated icon handling to use QStyle::standardIcon() where possible.
+
+- QMetaObject
+
+      * 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
+        paint device boundaries.
+
+      * Fixed a pixel artifact issue that occurred when drawing cosmetic
+        diagonal lines.
+
+      * Fixed opaque backgrounds so that they are identical on all
+        platforms.
+
+      * Optimized drawing of cosmetic lines at angles between 315 and 360
+        degrees.
+
+      * Added the setRenderHints() function.
+
+      * Fixed a memory corruption issue in drawEllipse().
+
+- QPixmap
+
+      * Fixed crash caused by setting a mask or alpha channel on a pixmap
+        while it was being painted.
+
+      * Changed load() and save() to no longer require a format string.
+
+      * Ensured that grabWidget() works before the specified widget is first
+        shown.
+
+- QPluginLoader
+
+      * Added errorString() to report the causes of errors when plugins fail
+        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
+        specific child widgets in a scroll area.
+
+- QScrollBar
+
+      * Ensured that a SliderMove action is triggered when the slider value is
+        changed through a wheel event.
+
+- QSet
+
+      * Added QSet::iterator and QMutableSetIterator.
+
+- QSettings
+
+      * Store key sequences as readable entries in INI files.
+
+      * Detect NFS to prevent hanging when lockd isn't running.

+
+      * Added the setAutoRepeat(bool) function to disable auto-repeating
+        actions on keyboard shortcuts.
+
+- QSize
+
+      * Fixed potential overflow issue in scale().
+
+- QSlider
+
+      * Added support for jump-to-here positioning.
+
+- QSortFilterProxyModel
+
+      * Handle source model changes (e.g., data changes, item insertion
+        and removal) in a fine-grained manner, so that the proxy model
+        behaves more like a "real" model.
+
+      * Added sortRole, filterRole and dynamicSortFilter properties.
+
+      * Perform stable sorting of items.
+
+      * Fixed support for drag and drop operations where one item is dropped
+        on top of another.
+
+      * Ensure that persistent indexes are updated when the layout of the
+        source model changes.
+
+      * Made match() respect the current sorting and filtering settings.
+
+      * Forward mimeTypes() and supportedDropActions() calls to source
+        models.
+
+      * Added the ability to filter on all the columns.
+
+      * Added the filterChanged() function to enable custom filtering to be
+        implemented.
+
+- QSqlQuery
+
+      * Added execBatch() for executing SQL commands in a batch. Currently
+        only implemented for the Oracle driver.
+
+      * Fixed a case where executedQuery() would not return the executed
+        query.
+
+- QSqlRelationalTableModel
+
+      * Fixed issue related to sorting a relational column when using the
+        PostgreSQL driver.
+
+      * revertAll() now correctly reverts relational columns.
+
+- QStackedLayout
+
+      * Fixed crash that occurred when removing widgets under certain
+        conditions.
+
+- QStackedWidget
+
+      * Fixed crash that occurred when removing widgets under certain
+        conditions.
+
+      * Fixed issue where the size hint of the current widget would not be
+        respected.
+
+- QStandardItemModel
+
+      * Added an item-based API for use with QStandardItem.
+
+      * Reimplemented sort().
+
+      * Added the sortRole property.
+
+- QStatusBar
+
+      * Added the insertWidget() and insertPermanentWidget() functions.
+
+- QString
+
+      * Added support for case-insensitive comparison in compare().
+
+      * Added toUcs4() and fromUcs4() functions.
+
+- QStyle
+
+      * Added the following style hint selectors:
+        SH_Slider_AbsoluteSetButtons, SH_Slider_PageSetButtons,
+        SH_Menu_KeyboardSearch, SH_TabBar_ElideMode, SH_DialogButtonLayout,
+        SH_ComboBox_PopupFrameStyle, SH_MessageBox_TextInteractionFlags,
+        SH_DialogButtonBox_ButtonsHaveIcons, SH_SpellCheckUnderlineStyle,
+        SH_MessageBox_CenterButtons, SH_Menu_SelectionWrap,
+        SH_ItemView_MovementWithoutUpdatingSelection.
+
+      * Added the following standard pixmap selectors:

+        values.
+
+      * Fixed support for gradient transformations.

+
+- QSyntaxHighlighter
+
+      * Added various performance improvements.
+
+- Qt namespace

+
+      * Non-pixmap based styles will now fill the background of the tab with
+        the palette's window role.
+
+- QTabletEvent:
+
+      * Ensured that QTabletEvents are dispatched with the proper relative
+        coordinates.
+
+      * Added proximity as another type of a tablet event (currently only sent
+        to QApplication).
+
+- QTableView
+
+      * Added API for spanning cells.
+
+      * Ensured that cells are selected when the user right clicks on them.
+
+      * Added a corner widget.
+
+      * Added the setSortingEnabled property.
+
+- QTableWidget
+
+      * Added the clearContents() function to enable the contents of the view
+        to be cleared while not resetting the headers.
+
+      * QTableWidget now uses stable sorting.
+
+      * Allow sorting of non-numerical data.
+
+      * Add convenience table item constructor that takes an icon as well as
+        a string.
+
+- QTabWidget
+
+      * Added missing selected() Qt3Support signal.
+
+      * Clarified documentation for setCornerWidget().
+
+      * Ensured that the tab widget's frame is drawn correctly when the tab
+        bar is hidden.
+
+      * Ensured that the internal widgets have object names.
+

+
+      * Improved pagination of tables across page boundaries.
+
+- QTextEdit
+
+      * Fixed append() to use the current character format.
+
+      * Changed mergeCurrentCharFormat() to behave in the same way as
+        QTextCursor::mergeCharFormat, without applying the format to the
+        word under the cursor.
+
+      * QTextEdit now ensures that the cursor is visible the first time the
+        widget is shown or when replacing the contents entirely with
+        setPlainText() or setHtml().
+
+      * Fixed issue where the setPlainText() discarded the current character
+        format after the new text had been added to the document.
+
+      * Re-added setText() as non-compatibility function with well-defined
+        heuristics.

+      * Added the setFormat() function to enable the cell's character format
+        to be changed.
+
+- QThread
+
+      * Related to changes to QObject, currentThread() always returns a
+        valid pointer. (Previous versions of Qt would return zero if called
+        from non-QThread threads; this does not happen in Qt 4.2).
+
+- QToolBar
+
+      * Introduced various fixes to better support tool buttons, button
+        groups and comboboxes in the toolbar extension menu.
+
+      * Fixed crash that occurred when QApplication::setStyle() was called

+        the valid area for the tooltip. (If you move the cursor outside this
+        area the tooltip will hide.)
+
+      * Added a widget attribute to show tooltips for inactive windows.
+

+        other platforms.
+
+- QLibrary
+
+      * Removed the dependency on dlcompat for library loading and resolving
+        in favor of native calls. This means that you can unload libraries
+        on Mac OS X 10.4 or later, but not on 10.3 (since that uses dlcompat

+
+- QScrollBar
+
+      * Improved handling of the case where the scrollbar is to short to
+        draw all its controls.
+
+- QTextEdit
+
+      * Improved the look of the widget to fit in with the native style.
+
+- QWidget
+
+      * All HIViewRefs inside Qt/Mac are created with the
+        kWindowStandardHandlerAttribute.

+- QGLWidget
+       
+      * Fixed usage of GL/WGL extension function pointers. They are now
+        correctly resolved within the context in which they are used.
+
+- QGLColormap
+
+      * Fixed cases where the colormap was not applied correctly.
+
+- QMenu
+ 
+      * Made it possible for popup menus to cover the task bar.
+
+- QPrinter
+
+      * Added support for printers that do not have a DEVMODE.
+
+      * Fixed a drawing bug in the PDF generator on Windows 98/Me.
+

+        Win95/98/Me.
+
+      * Allow keys to contain HKEY_CLASSES_ROOT and HKEY_USERS to allow all
+        registry keys to be read and prevent unintentional use of

+- QWindowsStyle
+
+      * We no longer draw splitter handles in Windows style. This resolves
+        an inconsistency with XP style, so that the two styles can use the
+        same layout interchangeably. Note that it is fully possible to style
+        splitter handles (if a custom style or handle is required) using
+        style sheets.
+
+      * Disabled comboboxes now have the same background color as disabled
