+Qt 3.1 introduces many significant new features and many improvements
+over the 3.0.x series. For an overview of the main changes between
+3.0.x and 3.1, look at the changes-3.1.0-b1 file. This file describes
+the changes between Qt 3.1 beta1 and Qt 3.1 beta2.
+
+
+****************************************************************************
+* General *
+****************************************************************************
+
+The binary incompatibilities that were introduced in Qt 3.1 beta1
+have been fixed.
+
+****************************************************************************
+* Library *
+****************************************************************************
+
+- QAction
+ Don't update when nothing has changed.
+
+- QActionGroup
+ Syncronize comboboxes correctly for groups with
+ separators. Set the initial currentItem of comboboxes to the
+ action that is on when adding the group. Emit activated signal
+ for non-toggle actions selected from a combobox. Apply the
+ state of the action group for new widgets.
+
+- QApplication
+ Correctly set the accept() flag on accel events. Obsoleted
+ processOneEvent(), we have a better way for integrating
+ eventloops now. (See QEventLoop's documentation.)
+ Windows only: reserve more space for very long application
+ filenames.
+
+- QCheckTableItem
+ Use the colorgroup passed in for the background color and not
+ the viewport's.
+
+- QColor
+ Windows only: Fix palette allocation and ManyColor mode on
+ Windows.
+
+- QComboBox
+ Emit activated() signals from the wheel event handler.
+
+- QComboTableItem
+ Make sure stringlist is updated even if setStringList() is
+ called while an editor exists.
+
+- QDataTable
+ Windows only: If edit confirmation was switched on and
+ the user cancelled an update by clicking in a different field,
+ the current row was needlessly changed.
+
+- QDateTimeEdit/QTimeEdit
+ Now supports wraparound for time editing.
+
+- QDesktopWidget
+ Windows only: Allow explicit creation of QDesktopWidgets.
+
+- QDns
+ Fix a crash when a QDns object is deleted in a slot connected
+ to its resultsReady() signal.
+
+- QDockWindow
+ Windows only: Don't pass window activation around
+ unnecessarily when the activation is ignored anyway. Also
+ fixed repaint errors while dragging dock windows. Remove
+ floating windows from the mainwindow's internal lists when
+ deleting.
+
+- QEventLoop
+ Renamed processNextEvent(flags,bool) to processEvents(flags)
+ and introduced new ProcessEvents flag, WaitForMore. Remove
+ processOneEvent since it is redundant.
+
+- QFileDialog
+ Windows only: Disable NTFS permission lookup during filedialog
+ population. This can take a long time, and the information is
+ not really required.
+
+- QGLContext
+ Added a workaround to get overlays to work on ATi FireGL
+ cards.
+
+- QGLWidget
+ Added support for rendering text into a GL context with the
+ renderText() calls.
+
+- QHeader
+ Draw the sort arrow at the right position with multi-line
+ header labels. Scale the correct sections when the header
+ sections are reordered. Respect orientation() in sizeHint().
+
+- qHeapSort()
+ Fixed to only require operator<, instead of a mix of
+ operator<, <=, and >.
+
+- QIconView
+ Optimize updates on focus/window activation changes.
+
+- QLibrary
+ Windows only: only append ".dll" extension if no extension has
+ been provided.
+
+- QListBox
+ Don't call ensureCurrentVisible() in resizeEvent() unless the
+ current item was visible when you started resizing.
+
+- QListView
+ Don't draw the cell if the cell wouldn't be visible due to
+ having a width or height of 0. Don't call cancelRename() when
+ the rename was OK'd. When showing a tooltip make sure it's
+ only for that column and not for the whole item.
+
+- QMacStyle
+ Many improvements to follow the native style more closely.
+
+- QMainWindow
+ Close all floating dockwindows of the mainwindow in the close
+ event.
+
+- QMenuData
+ Make removeItem(int id) work on trees like the other functions
+ that take IDs as arguments.
+
+- QObject
+ Make sender() a safer function to use:
+ - it cannot be dangling anymore (points to 0 if the sender was
+ deleted or disconnected)
+ - it maintains its value after other signals have been emitted
+ Fixed compatibility problem in connect(). Remove quadratic
+ behaviour in insertChild()
+
+- QPicture
+ Proper streaming for null pictures.
+
+- QPixmap
+ X11 only: allow grabWindow() to work on a screen other than
+ the default screen.
+
+- QPopupMenu
+ Draw submenu items disabled if the submenu is disabled. Fix
+ null-pointer dereferencing for dynamically changing menus.
+
+- QProcess
+ Windows only: make the tryTerminate() function work for
+ windows applications (it still does not work for
+ consoleapplications, though).
+
+- QSocket
+ Don't crash if the readBlock() returned 0.
+
+- QSplitter
+ addWidget() now reparents the widget if necessary.
+
+- QTable
+ Set the table of the item to the table in insertItem(), so
+ takeItem()/insertItem() can be used to move items between
+ tables.
+
+- QWidget
+ Clear WDestructiveClose before calling deleteLater() on
+ widgets. Event processing during destruction might otherwise
+ have another close event come along, which would issue another
+ deleteLater() call. Added a new function toggleShowHide(bool show).
+ Simplified visible() handling and added a convenience property
+ "shown" and a write function for "hidden". Save WFlags in
+ showFullScreen() and restore them so flags are remembered
+ correctly.
+
+- QWindowsStyle
+ Make the Windowsstyle obey the system's scrollbar widths.
+
+- qUncompress()
+ Don't hang forever if the expected size passed in is 0. Return
+ an empty bytearray if something went wrong instead of garbage
+ data.
+
+
+
+
