+compatibility (source and binary) with Qt 4.4.0.
+
+The Qt version 4.4 series is binary compatible with the 4.3.x series.
+The Qt for Embedded Linux version 4.4 series is binary compatible with
+the Qtopia Core 4.3.x series. Applications compiled for 4.0, 4.1, 4.2,
+and 4.3 will continue to run with 4.4.
