Revision control
++ Qt 4.6.2 is a bug-fix release. It maintains both forward and backward
++ compatibility (source and binary) with Qt 4.6.0 and 4.6.1. For more
++ details, refer to the online documentation included in this
++ distribution. The documentation is also available online:
++
++
++ The Qt version 4.6 series is binary compatible with the 4.5.x series.
++ Applications compiled for 4.5 will continue to run with 4.6.
++
++ Some of the changes listed in this file include issue tracking numbers
++ corresponding to tasks in the Qt Bug Tracker, the (now obsolete) Task
++ Tracker, or the Merge Request queue of the public source repository.

++ ****************************************************************************
++ * Platform Specific Changes *
++ ****************************************************************************
++
++ Qt for Linux/X11
++ ----------------
++ - Fix a bug where QPixmap::serialNumber was not set on a transformed pixmap
++ in Qt/X11.
++ - Fixed a crash when an input method tries to create a widget after the
++ application is destroyed.
++ - [QTBUG-6952] Fixed a problem using NoButtons in spinbox with QGtkStyle.
++ - [QTBUG-7504] Fixed missing focus rect on check- and radiobutton with
++ some GTK+ themes.
++ - [QTBUG-6522] Fixed missing menu separator in some GTK+ themes.
++
++ Qt for Mac OS X
++ ---------------
++
++ - [QTBUG-7832]: Restored missing margins around non-unified toolbars.
++ - [QTBUG-7312]: Menubar and dock disappear after hiding a fullscreen widget
++ on Cocoa.
++ - [QTBUG-7481]: Re-added the Close button in QPrintPreviewDialog for
++ Mac/Carbon.
++ - [QTBUG-7522]: Drawing fake buttons using QMacStyle+QStyleOptionViewItemV4
++ lead to crash.
++ - [QTBUG-7625]: Calling showFullScreen() then showNormal() on a widget results
++ in top menu hiding.
++ - [QTBUG-7086]: QFileDialog now correctly responds to fileMode & acceptMode
++ changes.
++ - [QTBUG-7162]: Fixed a crash in Designer when previewing a QMainWindow with
++ native toolbar.
++ - [QTBUG-7305]: Fixed a crash when deleting QMainWindow with native toolbar
++ on Cocoa.
++ - [QTBUG-6882]: Fixed a text layout issue with QHeaderView in right-to-left
++ mode.
++
++ DirectFB
++ --------
++
++ - Fix a bug where QPixmap::serialNumber was not set on a transformed pixmap
++ in DirectFB.
++ - Reimplement QPixmapData::scroll for QDirectFBPixmapData which optimizes
++ QPixmap::scroll.
++ - Fix a rendering issue for semi-transparent top level windows in DirectFB.
++ - Make it possible to fall back to the raster engine for stretch blits in
++ DirectFB using QT_NO_DIRECTFB_STRETCHBLIT.
++
++ Qt for Symbian
++ --------------
++
++ - [QTBUG-6556] Improve the DEF file handling scheme, to allow simple enable/
++ disable of DEF file usage (for use _during development only_ to decouple
++ the need to update the DEF files at the precise point that symbols are
++ removed, therefore allowing builds by CI systems to succeed even if symbols
++ have been removed. This does not remove the need to update the DEF files
++ before release. NOTE: Builds generated using this flag are not binary
++ compatible with previous versions of Qt.)
++ - QProcess
++ * [QTBUG-7667] Fixed no-timeout case for QProcess::waitForFinished.
++ - qmake
++ * [QTBUG-7695] Added support for ifdeffing for manufacturer in generated
++ pkg files.
++ * [QTBUG-7908] Smart installer package generation support.
++ - Patch_capabilities script
++ * Added support for embedded sis name/uid patching.
++ - Qt deployment
++ * [QTBUG-7518] Backup and restore support for Qt libs.
++
++
++ ****************************************************************************
++ * Tools *
++ ****************************************************************************

++ a style sheet set on the main form.
++
++ - uic3
++ * [QTBUG-7404] Added option to preserve layout names set by Qt 3 Designer.
++
++ ****************************************************************************
++ * Important Behavior Changes *
++ ****************************************************************************
++
++ - QNetworkAccessManager cache
++ * QNetworkAccessManager will no longer return expired pages, as
++ stated in the documentation
++ * The behaviour of PreferCache and PreferNetwork modes now match
++ the documentation more closely
++
++ - QUrl
++ * QUrl will now accept hostnames ending in dot and will not treat
++ those as invalid hostnames
