+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.
+
+
+

+
+- 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.

+ one rather than replacing it.
+

+
+ * 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.

+
+ * 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.
+
+- QLabel
+
+ * Added support for text selection and hyperlinks.

+ * Improved handling of scaled pixmaps.
+
+ * Made handling of QMovie safer to avoid object ownership issues.
+
+- QLibrary
+
+ * Added support for hints to control how libraries are opened on UNIX
+ systems.
+
+ * Added errorString() to report the causes of errors when libraries
+ fail to load.
+

+ 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.

+
+ * 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.

+
+ * Added support to display buttons in the order required by

+
+ * Added combinedMatrix() which contains both world and viewport/window
+ transformations.
+
+ * Added the setOpacity() function.
+
+ * Added MiterJoins that are compliant with SVG miter joins.
+
+- QPainterPath
+
+ * Added the arcMoveTo() and setElementPosition() functions.
+

+ WindowStaysOnTopHint.
