Qt 5.9.1 is a bug-fix release. It maintains both forward and backward
|
|
compatibility (source and binary) with Qt 5.9.0.
|
|
|
|
For more details, refer to the online documentation included in this
|
|
distribution. The documentation is also available online:
|
|
|
|
http://doc.qt.io/qt-5/index.html
|
|
|
|
The Qt version 5.9 series is binary compatible with the 5.8.x series.
|
|
Applications compiled for 5.8 will continue to run with 5.9.
|
|

Deprecation Notice
|
|
------------------
|
|
|
|
- The following platforms or toolchains are deprecated and will be
|
|
removed as of Qt 5.11:
|
|
* Microsoft Visual Studio 2013
|
|
|
|
Important Behavior Changes
|
|
--------------------------
|
|
|
|
- The Q_REQUIRED_RESULT macro now expands to the C++17 attribute
|
|
[[nodiscard]] if the compiler supports it. Code using this macro needs
|
|
to pay attention to its placement, as C++ function attributes must come
|
|
before the declaration, unlike the GCC extension that this macro
|
|
previously expanded to.
|
|
|
|
Binary Compatibility Note
|
|
-------------------------
|
|
|
|
- The variable QOperatingSystemVersion::MacOSHighSierra was added in this
|
|
release. Code that uses this variable will not run under Qt 5.9.0. If
|
|
backwards compatibility is desired, use instead
|
|
QOperatingSystemVersion(QOperatingSystemVersion::MacOS, 10, 13)
|
|
|
|
Third-Party Code
