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.

****************************************************************************
* Qt 5.9.1 Changes *
****************************************************************************
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
----------------
- Sqlite was updated to version 3.16.2.
- Deleted the src/3rdparty/atspi2 directory.
QtCore
------
- [QTBUG-60558] Fixed a bug that caused QInternal::unregisterCallback to
crash on exit.
- [QTBUG-61034] QT_NO_EXCEPTIONS is now reliably set when using Clang, even
in Objective C++ mode.
- QHash/QMultiHash:
* [QTBUG-60395] Fixed operator== so that two containers compare equal when
there are multiple values with the same key.
- QStorageInfo
* [QTBUG-61096] Fixed a hang on certain systems when retrieving
information from unresponsive filesystems.
- QTimeZone:
* [QTBUG-60595] Fixed sending IANA standard UTC-offset QTimeZones
through QDataStream, which previously came out invalid after
deserialization.
moc
---
- [QTBUG-61204] moc no longer errors out if a C++ keyword is #define'ed
Platform Specific Changes
-------------------------
- macOS / iOS:
* [QTBUG-41978] QCollator now respects the ignorePunctuation property on
Apple based platforms correctly.
* [QTBUG-61205] Fixed the architecture information in QSysInfo.
* QSysInfo and QOperatingSystemVersion now support the newest versions of
Apple's operating systems.
* [QTBUG-61053] Fixed SSL certificate verification on iOS with Secure
Transport back-end.
- Windows:
* [QTBUG-61315] Fixed invalid sorting of custom environment variables set
via QProcessEnvironment when starting subprocesses.

configure & build system
------------------------
- [QTBUG-58372] The SQL driver plugins can be built separately again.
Note that it is necessary to configure the whole sqldrivers directory.
- [QTBUG-60925][Unix] Fixed library retrieval from pkg-config. Again.
- [QTBUG-60936] Fixed module version number in Qt modules' cmake config files.
- [QTBUG-61017] Fixed configure hanging upon selecting commercial license.
- [QTBUG-61044] Fixed license checker invocation on 32 bit systems.
- [MinGW] The gold linker is no longer used.
qmake
-----
- [QTBUG-38452][Android] Fixed overwriting of INSTALLS for target, and the
resulting bogus attempts to write to /libs on the host system.
- [QTBUG-42830][Android] INSTALL targets are no longer created for static
libraries.
- [QTBUG-40825][QTBUG-59457][Unix] Fixed various makespecs to append shared
include and library locations only at the end of the search lists.
- [QTBUG-52383][Windows] midl and rc are now invoked with /NOLOGO.
- [QTBUG-58391][MSVC] MSVC extensions are not disabled any more when
querying the compiler for the predefined macros to pass to moc.
- [QTBUG-59431][VS] Fixed parsing of /utf-8 option. Again.
- [QTBUG-60895][VS] Fixed .vcxproj generation for ActiveQt server projects.
- [QTBUG-60059] qmake will now be more verbose when it fails to run the
compiler while querying the toolchain's properties.
- Various QT_<compiler>_VERSION variables were reverted to refer to the
toolchain Qt was built with. The current toolchain's versions can be
found in the QMAKE_<compiler>_VERSION variables.
- QMAKE_DEFAULT_{INC,LIB}DIRS is now populated also when using clang.
- [MinGW] Re-builds of static library projects will now create a new library
instead of updating the previously built one.
- [VS] Unknown /Zc:XXX options are no longer complained about.
