+Qt 3.0.1 is a bugfix release. It maintains both forward and backward
+compatibility (source and binary) with Qt 3.0.0
+
+
+****************************************************************************
+*			    General					   *
+****************************************************************************
+
+- Style Engine fixes
+	Qt 3.0 introduced a new and more flexibile style engine. This
+	release should fix most of the small visual flaws that the new
+	styles introduced. It also greatly improves appearance in
+	right-to-left mode.
+
+- MS-Windows XP
+	This is the first release to fully support Windows XP,
+	including the new themable GUI styles.
+	The Windows XP style can only be built as a plugin, which requires
+	Qt to be configured as a shared library. To build the plugin
+	you must install a Microsoft Platform SDK for October 2001
+	or later. Your INCLUDE and LIB environment variables must
+	point to the respective directories in the SDK installation.
+
+- Reverse (right-to-left) layouts
+	Many classes have improved support for right-to-left layouts.
+
+- Compile fixes 
+	Solaris 7 Intel, g++ version 2.8.1.
+
+- Documentation updates
+	Some new and improved diagrams and minor textual revisions.
+
+- Mac only: Drag'n'drop
+	Mac only: QDropEvents can decode HFS flavors.
+
+- X11 only: Multi-head (multi-screen) improvements
+	Support for different TrueColor depths on each head (screen).
+	Drag'n'drop support across multiple screens. Tooltips always
+	stay on the correct screen. Improved OpenGL support on
+	multiple screens. Qt 3.1 will support different color depths
+	on every screen (e.g. one TrueColor screen, one 8-bit
+	PseudoColor and one 8-bit GreyScale).
+
+
+****************************************************************************
+*			   Library					   *
+****************************************************************************
+
+- QAction
+	Fixed a memory leak in conjunction with action accelerators.
+	Turn toggle actions off when toggling is turned off with
+	setToggleAction(FALSE);
+
+- QApplication
+	Shared double buffers are cleaned up on destruction. 
+	Creating and using multiple QApplications in the same process
+	is supported.
+	- Solaris only: Default to the Interface System font (which is
+	  the default for the CDE)
+	- Win32 only: When WM_QUERYENDSESSION is received, _flushall
+	  is called to ensure that all open streams and buffers are
+	  flushed to disk (or to OS's buffers). 
+	  Better support for more input methods (e.g. Chinese). 
+	  Enter events are not propagated to modally blocked widgets. 
+	  Key_BackTab events are generated rather than Shift+Key_Tab.
+	  Floating toolbars are blocked when the application is modal. 
+	  Move and Resize are disabled in the system menu for
+	  maximized toplevel windows
+	- WinXP only: WM_THEMECHANGED messages are handled; widgets
+	  are repolished with the appropriate style.
+	- X11 only: Removed misleading warning message for main
+	  widgets on heads (screens) other than the default head.
+	  Input context: Solved a memory leak in Xlib, and saved a
+	  server round trip when updating the microfocushint. 
+	  Worked around some broken XmbLookupString implementations
+	  that do not report buffer overflows correctly. 
+	  Key events are never given to a widget after clearFocus()
+	  has been called for that widget; this is the same behavior
+	  as Windows.
+
+- QAquaStyle (MacOS X only)
+	More optimizations and several minor visual bugs fixed.
+
+- QCanvas
+	Erase any exposed empty space when shrinking the canvas.
+
+- QCanvasPixmapArray
+	Initialize the framecount to 0.
+
+- QCanvasView
+	Optimize background pixmaps: potentially they were drawn
+	twice, first untranslated then translated.
+
+- QClipboard (X11 only)
+	The race conditions that cause KDE to lock-up occasionally
+	should now be fixed.
+
+- QComboBox
+	Fixed behavior with non-selectable items. Fixed a crash when
+	calling setCurrentItem(-1). Fixed autoscrolling when dragging
+	the mouse directly after opening the dropdown.
+
+- QColor
+	Make invalid named colors return a non-valid QColor (as
+	documented).
+
+- QColorDialog (Win32 only)
+	Use WStyle_DialogBorder, since resizing this dialog does not
+	make much sense.
+
+- QCommonStyle
+	Respect QApplication::globalStrut() in scroll bars. Support
+	reverse layout in QTitleBar.
+
+- QCursor
+	Safer cleanup of cursor shapes (avoids possible free'd memory
+	read)
+	- Win32 only: fixed application override cursor with mouse
+	  grabbing.
+
+- QDate
+	Fixed some possible overflows.
+	- Win32 only: Improve locale support for short day and month
+	  names etc. Initialize milliseconds correctly.
+
+- QDateTimeEdit
+	Display AM/PM if set by locale. Improved sizeHint().
+
+- QDockAarea
+	More reliable sizeHint(). Better support for reverse layouts.
+
+- QDockWindow
+	Emit the placeChange() signal more reliably. Avoid floating
+	docks popping up everywhere before they have been positioned
+	and laid out.
+
+- QDesktopWidget
+	- X11 only: When using normal dualhead (not Xinerama), make
+	  sure we report the correct screen number.
+	- Win32 only: refresh on WM_DISPLAYCHANGE.
+
+- QFrame
+	New panel styles LineEditPanel and TabWidgetPanel. This was
+	required by the new for Windows XP support.
+
+- QFileDialog
+	Show unicode filenames to the user rather than encoded ASCII
+	(e.g. previously latin1 characters were shown as "%XX"
+	escapes).
+	Fixed multiple-selection of FTP files. 
+	Emit signal fileHighlighted in existingfile mode.
+	- Mac only: Fixed existingFolder(). Fixed window position so
+	  that it will never fall outside the screen.
+	- Win32 only: since files, directories and drives are not case
+	  sensitive, we don't add an extra entry in the paths box if
+	  the path already exists but with different case.
+
+- QFileInfo (Unix only) 
+	Make sure that symlinks pointing to invalid/non-existing
+	targets are reported as symlinks.
+
+- QFont
+	Ensure a rounded-off value is returned from pointSize().
+	- x11 only: improved line width calculation. Fixed off by one
+	  error in interpreting Xft font extents. Allow the use of
+	  both Xft and non Xft fonts in the same application. Make
+	  sure fonts are antialiased by default when using
+	  xftfreetype.
+
+- QFontDialog
+	Prevent re-laying out when the size of the preview label
+	changes.
+
+- QFtp
+	In parseDir(), do not compare English month names to
+	shortMonthName(), since the latter is localized.
+
+- QGList
+	Make self-assignments work.
+
+- QGLWidget
+	Fixed ARGB to RGBA conversion on BigEndian systems.
+	- Win32 only: fixed colormap for 8-bit RGBA GL mode.
+	- X11 only: multiple heads with different color depths fixes.
+
+- QHebrewCodec
+	Assume the bidi algorithm is a reversible operation for the
+	visual 8859-8 codec. This is not true for very complex strings
+	but should hold in most cases.
+
+- QIconSet
+	Fixed detach() to really detach the internal pixmaps. In case
+	no image formats are installed, show black pixmaps rather than
+	ASSERT.
+
+- QImage
+	Allow 16-bit DIBs. Allow > 32767 level PNMs. 
+	Fixed smoothscale() for the following bug: whenever 
+	(new_width / original_width * 4096) is not an integer the last
+	column of the scaled image is black.
+
+- QImageIO
+	Fixed plugin loading in cases where the image format is
+	explicitly defined.
+
+- QInputDialog
+	Disable the OK button when input is not Acceptable.
+	(See QValidator.)
+
+- QLabel
+	When showing rich text with tables (via QSimpleRichtext),
+	avoid drawing the table background.
+
+- QLayout
+	In reverse layout mode: fix off by one error when laying out
+	right to left or bottom to top.
+
+- QLineEdit
+	Fixed offset calculation for horizontal scrolling. Invoke
+	validator when the user presses Backspace or
+	Delete. Compression of the undo/redo stack fixed. Security: do
+	not reveal the position of spaces with Ctrl+RightArrow or
+	Ctrl+LeftArrow in password mode.
+
+- QListBox
+	Append items at the proper position even after sorting the
+	content. Made QWidget::setBackgroundMode() work correctly.
+
+- QListBoxPixmap
+	Use the function pixmap() when drawing the pixmap, so users
+	can reimplement QListBoxPixmap::pixmap().
+
+- QListView
+	Fix misalignment of checkbox click zone. Make the selected and
+	focus rectangles cover the entire column for QCheckListItems
+	if the listview root is not decorated. Make
+	QWidget::setBackgroundMode() on the viewport work correctly.
+	Comply with user interface guidelines: clear the selection
+	when a click is in an empty area unless the Ctrl key is down.
+	Fixed possible crash when starting a rename with a double
+	click. Smarter ensureItemVisible(). Draw listview background
+	in paintEmptyArea() with the current style. Ensure the
+	listview always has a current item.
+
+- QMainWindow
+	Better laying out of dockareas when they are all empty.
+	Otherwise an empty QMainWindow looks unappealing in a
+	workspace. Maintain the toplevel layout's resize mode.
+
+- QMessageBox
+	Avoid double deletion if the parent is destroyed while the
+	messagebox is open. Support y/n/c shortcuts without needing
+	the Alt key modifier.
+
+- QMovie
+	Allow pause() and restart() with MNG.
+
+- QMultiLineEdit
+	Remove internal trailing space when returning a textline with
+	textLine(int) and querying lineLength(int).
+
+- QPainter
+	The boundingRect() should now work properly for the
+	combination richtext, right-aligned and an empty initial rect.
+	Handle DontClip-flag in the painter's complex drawText()
+	function. Reset the cached composition matrix (and inverse)
+	when reinitialising a painter.
+
+- QPicture
+	Fixed the loading of binaries from older Qt versions.
+
+- QPixmap
+	grabWidget(): when the widget sets WRepaintNoErase it might
+	erase itself with the non-redirected QWidget::erase(); restore
+	those areas.
+	- X11 only: (with XRENDER extension) when copying a pixmap,
+	  bitBlt the entire data into the new pixmap instead of using
+	  alpha composition.
+
+- QPopupMenu
+	Fixed strange side effects with the menu effects. Support
+	minimumSize() for popups. Fixed a navigation issue where
+	Key_Right under certain circumstances was not propagated to
+	the menu bar. Speedups when disabling/enabling menu items
+	before showing them.
+	- X11 only: Fixed mouse and keyboard grabbing side effects
+	  with popup menu effects enabled.
+
+- QPrintDialog (built-in dialog)
+	Use the text in the lineedit for the file dialog.
+
+- QPrinter
+	Fixed crash when printing with incomplete combined unicode
+	fonts.
+	- Win32 only: fixed a very rare and mysterious crash.
+
+
+- QPSPrinter
+	Make sure the fontPath is read correctly by the postscript
+	driver, and the qtconfig program. Small memory leaks closed.
+	Better support for Asian printing. Limit line length of
+	Postscript DSC comments to 255 chars (as per the postscript
+	specification).
+
+-  QRichText
+	Fixed handling of &nbsp. Support both <qt title="..."> and
+	<title>. Avoid painting \n at the end of lines (these
+	sometimes appeared as an empty unicode box). Fixed find() in
+	"whole words only" mode. Fixed unicode auto alignment. Made
+	cursor movement in BiDi paragraphs compliant with MS-Windows.
+	Fixed paragraph right and center alignments when using <br>
+	tags. Fixed superscript/subscript confusion.
+
+- QScrollBar
+	Allow scrolling with modifier keys pressed.
+
+- QScrollView
+	Made autoscrolling work with drag and drop. Never generate
+	paintevents that are outside the visible area.
+
+- QSettings
+	- Unix only: search paths are valid for individual objects,
+	  NOT every object (windows behavior). When reading files,
+	  don't replace the old groups with contents of the new
+	  groups; merge them instead. Properly escape backslashes and
+	  newlines.
+	- win32 only: improved error handling. Fixed subKeyList() and
+	  entryList() for empty paths.
+
+- QSimpleRichText
+	Correctly transform clipping rectangle.
+
+- QSizeGrip
+	Reverted sizeHint() to the old size to avoid making the
+	statusbar a tiny bit too big. Support right-to-left layout.
+
+
+- QSgiStyle
+	Made the combobox arrow look nicer. Fixed disabled combobox
+	drawing.
+
+- QSlider
+	Fixed click handling for reverse layouts.
+
+- QSpinBox
+	Usability fix: when changing a value with the up/down arrow
+	keys or with the arrow buttons, select the new value.
+
+- QSplitter
+	Use the actual QSplitter pointer as documented (and not a
+	QSplitterHandle pointer) as the parameter to the
+	QStyle::sizeForContents() call. Fixed reverse layouts when
+	splitter movement is constrained.
+
+- QSqlRecord
+	Fixed double increment of the iterator in certain
+	circumstances.
+
+- QString
+	Fixed QString::setLatin1() when the length parameter is 0.
+	- Unix only: Use strcoll() in QString::localeAwareSorting().
+	- Mac only: clarify that local8Bit() is always utf8().
+
+- QStyle
+	New frame styles for tab widgets, window frames and line edit
+	controls. This was required by the new support for Windows XP.
+	Added SH_ScrollBar_StopMouseOverSlider style hint so that one can
+	turn on (or off) the ability to stop pageup/pagedown when the
+	slider hits the mouse (this is needed for Aqua on MacOS X).
+
+- QSvgDevice
+	Many fixes for saving and restoring attributes that are not
+	part of QPainter. Processing of 'tspan' elements. Now uses
+	double instead of int for internal 'path' arithmetic for
+	better scaling results. Supports QPicture's coordinate
+	transformations.
+
+- QTabBar
+	Fixed the focus rectangles and spacing with icons and label
+	texts.
+
+- QTable
+	Improved layout in right-to-left mode. Fixed adjustRow() when
+	using header items with icon sets. Do not let hidden
+	columns/rows re-appear when adjusting. Update header correctly
+	when changing a table's dimensions. Correctly reset the
+	updatesEnabled flag in sortColumn(). Fixed modifying the
+	contents of a combobox or checkbox table item while it is the
+	current cell.
+
+- QTableItem
+	Make sure an item cannot span over a table's maximum number of
+	rows and columns.
+
+- QTabWidget
+	Constrain the sizehint to avoid having oversized dialogs.
+
+- QTextCode
+	Rename iso8859-6-I to to 8859-6. The old name is still
+	supported for backwards compatibility.
+	- Win32: implemented locale().
+	- Mac: implemented locale().
+
+- QTextDrag (Win32 only)
+	Performance improvements in encodedData().
+
+- QTextEdit
+	Fixed HTML output. New property tabStopWidth. Fixed append()
+	and made it smarter: it only scrolls to the end if the view
+	was scrolled to the end before. Proper reformatting when
+	switching word wrap policies. Do not blink the cursor when the
+	textedit is disabled. Make isModified() return the new value
+	in slots connected to the modificationChanged() signal.
+	- X11 only: middle mouse selection pasting sets the cursor
+	  position.
+
+- QTextStream
+	Faster string output in latin1 mode.
+
+- QThread
+	- Unix only: initialize threads in non-GUI mode as well.
+	- Win32 only: fixed the initial value of QThread::running().
+
+- QToolButton
+	Fixed unwanted occurences of delayed popup menus.
+
+- QUrlOperator
+	Fixed the cache, so that QUrlInfo::name() is set correctly for
+	renamed files. This bug also affected QFileDialog. More
+	careful check whether a file is writable before renaming or
+	deleting it.
+
+- QValueVector
+	Make operator==() const. Fixed some sharing issues.
+
+- QVariant
+	Fixed a few memory leaks when casting complex values to simple
+	types. Faster operator==().
+
+- QWaitCondition (Win32 only)
+	Fixed wakeAll().
+
+- QWhatsThis
+	Make QWidget::customWhatsThis() work with menu accelerators.
+	Avoid infinite loops with menu effects.
+
+- QWidget
+	Fix default focus so that setTabOrder( X, Y ); setTabOrder( Y,
+	Z ); gives focus to X, not Y or Z. Closing a modal dialog with
+	a double click on a widget could result in a mouse release
+	event being delivered to the widget underneath; this has been
+	fixed.
+	Set/Reset WState_HasMouse on DragEnter/DragLeave.
+	- Win32 only: obey WPaintUnclipped. Make reparent() with 0,0
+	  positions do the requested positioning.
+	- X11 only: when reparenting widgets to/from toplevel, make
+	  sure the XdndAware property is set. Make input methods work
+	  with servers other than kinput2. More fixes for 4Dwm's
+	  incompliance with ICCCM 4.1.5 regarding geometry handling.
+	  When hiding toplevel windows, we call XFlush() to avoid
+	  having popup menus hanging around grabbing the mouse and
+	  keyboard while the application is busy. Obey the 'erase'
+	  value in repaint(const QRegion& reg, bool erase).
+
+- QWindowsStyle
+	Various visual fixes, including fixes for right-to-left
+	mode. Most significantly the light source now comes from the
+	top left also in reverse layout the same as modern versions of
+	Windows.
+
+- QWorkspace
+	Support document windows without title bars. Scroll to top
+	left corner when cascading/tiling a scrolled workspace. Define
+	a proper baseSize() for workspace children. Fix some side
+	effects with the workspace's maximize controls on Windows
+	style. Don't raise windows over scrollbars. Clients can now
+	call adjustSize() on the workspace when their sizeHint()
+	changes. When showing two scrollbars, maintain a solid corner.
+	Obey a document window's maximum size when tiling.
