+  1. Please keep in mind that due to dropping the QTDIR variable recognition,
+     qmake.exe now unconditionally uses hard-coded paths to locate various Qt4
+     components (such as the include or source directory) during the makefile
+     generation process and therefore if you move the Qt source tree to another

+
+  2. This version of Qt for OS/2 includes the Extended system tray plugin for
+     XCenter/eCenter which is necessary to enable Qt support for the special
+     notification area on the XCenter/eCenter panel (called the "system tray")
+     which is used by many long-running applications to display their status.
+     In order to activate this support, you need to install this plugin to your
+     XCenter or eCenter. The plugin is built during the normal Qt build process
+     and can be found in the file \plugins\xcenter\xsystray.dll in the Qt source
+     tree. In order to install the plugin, do the following:
+
+     a. Copy xsystray.dll to <XWorkplace installation folder>\plugins\xcenter\
+        (on eComStation, this will be C:\ecs\system\ewps\plugins\xcenter\ where
+        C: is your boot drive).
+
+     b. Restart WPS.
+
+     c. Add the "Extended system tray" widget to the XCenter/eCenter panel using
+        the XCenter context menu ('Create new widget').
+
+     Note that if you upgrade from the previous version of the plugin then
+     please unlock xsystray.dll in the target folder using the UNLOCK.EXE
+     utility (which you can find in the LxLite package, for example) before
+     performing step a., otherwise the copy operation will fail.

 CHANGES
+
+Beta 4 (11-11-2009)
+
+  Improvements:
+
+  - Added sound support (implemented QSound class).
+
+  - Added system tray support (QSystemTrayIcon class). This support requires
+    the Extended system tray XCenter plugin to be installed. See the note above
+    on how to compile and install this plugin.
+
+  - Enabled QPlugin support on OS/2. This in turn enables SVG support for
+    QIcon (which is built as a Qt plugin DLL by default).
+
+  - Better widget modality support (widgets blocked by modality cannot be
+    activated and moved using the mouse and the title bar anymore).
+
+  - Added support for 'console' and 'windows' CONFIG options in .pro files.
+    Now, if 'windows' is present, the target executable will have the WINDOWAPI
+    attribute set which effectively makes it a PM application. This, in
+    particular, disables standard input, output and error streams so that when
+    started, the application will not have a console window attached to it and
+    will not support input/output redirection operators on the command line.
+    By default, 'console' mode is active unless you perform a release build and
+    the application is linked against the QtGui library ('QT = gui' in .pro),
+    in which case the default is 'windows'.
+
+  - Improved paint speed in Qt windows which should increase overall graphical
+    UI performance by 10%-20% in Qt4 applications.
+
+  - Implemented setting window icons for top-level windows (using
+    QWidget::setWindowIcon()).
+
+  - Added LxLite support to provide compression for executables and DLLs. The
+    compression is controlled by the 'exepack' CONFIG option which is turned on
+    by default for release builds if the LxLite executable is present in PATH
+    during the configure.cmd invocation. The compression may be turned off on a
+    per-project basis by adding a 'CONFIG -= exepack' line to the .pro file.
+
+  - Improved the section of this README.OS2 file that describes how to properly
+    set the LANG variable to have correct national characters in file names and
+    in window titles of Qt applications.
+
+  Fixes:
+
+  - QProcess: The executable's path was not always added to BEGINLIBPATH.
+
+  - Fixed-size top-level widgets could not be moved.
+
+  - Application crash after pressing a button in a dialog window that resizes
+    this dialog (for example, makes it bigger to show more information).
+
+  - Resizing top level windows using the top border broke mouse coordinates so
+    that Qt tought you pressed the mouse button in a different place of the
+    window than where you actually did it.
+
+  - Events posted with QCoreApplication::postEvent() were only processed upon
+    receiving a next message from the system. This caused funny delays such as
+    controls in a Qt window still indicating the input focus (the dotted
+    rectangle) after the window was deactivated and losing this indication only
+    when the mouse pointer was moved over the window.
+
+  - Don't replay mouse button press on a push button that is showing a popup
+    menu but instead hide the popup menu and unpress the button to get more
+    native look and feel.
+
+  - Deactivating the window with a push button showing a popup menu would hide
+    the popup but leave the button pressed.
+
+  - Fixed incorrect Qt dirty widget region calculation when processing WM_PAINT
+    messages. This fixes a lot of redraw problems (menu items in the main menu
+    bar, text in combo-boxes, various redraw problems in smplayer when switching
+    interfaces and going to/from fullscreen, and similar).
