| compatibility (source and binary) with Qt 4.4.1 and 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. |
