+
+Meta-Object System
+------------------
+
+Qt 4.0.0 introduced a change to the way type names outside the current
+scope were handled in signals and slots declarations and connections
+which differed from the behavior in Qt 3.x.
+
+Unfortunately, this could lead to signal-slot connections that were
+potentially type-unsafe. Therefore, in Qt 4.0.1 type names must be fully
+qualified in signal-slot declarations and connections.
+
+For example, in Qt 4.0.0, it was possible to write:
+
+ connect(socket, SIGNAL(error(SocketError)), ...);
+
+In Qt 4.0.1, the above connection must be made in the following way:
+
+ connect(socket, SIGNAL(error(QAbstractSocket::SocketError)), ...);
+
+
+Library
+-------
+
+Support for SGI Altix has been added for both gcc and Intel icc.
+
+
+QX11EmbedContainer and QX11EmbedWidget are now exported classes.
+
+This change only affects developers using Qt/X11 with gcc >= 4.0 and
+symbol visibility enabled. Applications built against Qt 4.0.1 that
+use these classes cannot be linked against Qt 4.0.0.
+
