| Qt 5.4.2 is a bug-fix release. It maintains both forward and backward | ||
| compatibility (source and binary) with Qt 5.4.1. Compatibility with Qt | ||
| 5.4.0 is also retained, except on Windows when using MSVC 2012 or MSVC | ||
| 2013. See note below. | ||
|
|
||
| For more details, refer to the online documentation included in this | ||
| distribution. The documentation is also available online: | ||

|
||
| The Qt version 5.4 series is binary compatible with the 5.3.x series. | ||
| Applications compiled for 5.3 will continue to run with 5.4 with the | ||
| exception of on Windows when using MSVC 2012 or MSVC 2013. See note | ||
| below. | ||

| **************************************************************************** | ||
| * Important Behavior Changes * | ||
| **************************************************************************** | ||
| - Restored binary compatibility with Qt 5.3.2 on Windows when using MSVC | ||
| 2012 or MSVC 2013. This means that Qt 5.4.1 and 5.4.2 are no longer | ||
| binary compatible with Qt 5.4.0 when using either of those compilers. | ||
| - [QTBUG-42594] OS X binary package: fixed incorrect linking to libraries in | ||
| /opt/local/lib | ||
| - EXIF orientation is no longer applied to JPEG images on read. EXIF | ||
| orientation on JPEG was introduced in 5.4.0, but due to a bug the most | ||
| common EXIF-format (big-endian) was not working until 5.4.1. 5.4.2 restores the | ||
| behavior of 5.4.0 and earlier for most EXIF-tagged JPEGs. | ||
| EXIF orientation will be an opt-in starting with Qt 5.5. | ||
