------
|
||
|
|
||
|
- [QTBUG-64529] Fixed a compilation issue with qfloat16 if AVX2 support is
|
||
|
enabled in the compiler. Since all processors that support AVX2 also
|
||
|
support F16C, for GCC and Clang it is recommended to either add -mf16c
|
||
|
to your build or to use the corresponding -march= switch.
|
||
|
|
||
|
- QCoreApplication:
|
||
|
* [QTBUG-58919] Fixed a crash if QCoreApplication is recreated on Windows
|
||
|
and the passed argv parameter is different.
|
||
|
|
||
|
- QFile:
|
||
|
* [QTBUG-64103] Fixed a regression in doing rename() on Android
|
||
|
Marshmallow.
|
||
|
|
||
|
- QFileInfo:
|
||
|
* [QTBUG-30148] Fixed isWritable() on Windows to return whether the given
|
||
|
file is writable only under current privilege levels. Previously, the
|
||
|
result would take into account privilege elevation.
|
||
|
|
||
|
- QMetaObject:
|
||
|
* [QTBUG-65462] Fixed a memory leak that happened when the new-style
|
||
|
call to invokeMethod() was used.
|
||
|
|
||
|
- QObject:
|
||
|
* [QTBUG-65712] Improved performance of QObject::deleteLater.
|
||
|
* Fixed a crash that could happen if the context QObject pointer passed to
|
||
|
new-style connect() was null.
|
||
|
|
||
|
- QPluginLoader:
|
||
|
* [QTBUG-65197] Fixed a bug that would cause the Qt plugin scanning
|
||
|
system to allocate too much memory and possibly crash the process.
|
||
|
|
||
|
- QProcess:
|
||
|
* [QTBUG-65076] Fixed a regression that made QProcess be unable to find
|
||
|
executables when the PATH environment variable on some Unix systems
|
||
|
wasn't set. This behavior should not be relied upon since many systems
|
||
|
do not have sensible fallback values for PATH.
|
||
|
|
||
|
- QRandomGenerator:
|
||
|
* [QTBUG-65414] Fixed compilation on Windows if the windows.h header was
|
||
|
included before this qrandom.h.
|
||
|
|
||
|
- QSettings:
|
||
|
* [QTBUG-64121] Fixed reading from NTFS symbolic links.
|
||
|
|
||
|
- QStandardPaths:
|
||
|
* [QTBUG-65076] findExecutable() will now apply the default value for
|
||
|
the PATH environment variable (as returned by the POSIX confstr(3)
|
||
|
function or found in <paths.h>) if the variable isn't set in the
|
||
|
environment.
|
||
|
* [QTBUG-65687] Fixed a memory leak with displayName() on Apple platforms.
|
||
|
* On Windows, it is now possible to resolve configuration paths even
|
||
|
without QCoreApplication created.
|
||
|
|
||
|
- QString:
|
||
|
* [QTBUG-65939] Fixed a regression from 5.9 that caused comparing
|
||
|
default-constructed QStrings to be sorted after non-empty strings.
|
||
|
|
||
|
- QTextBoundaryFinder:
|
||
|
* [QTBUG-63191] Fixed a bug in the generating of Unicode data, affecting
|
||
|
the joining properties of characters like U+200C ZWNJ.
|
||
|
|
||
|
- QXmlStreamWriter:
|
||
|
* [QTBUG-63538] Empty namespace URIs are now possible.
|
||
|
|
||
|
- State Machine:
|
||
|
* [QTBUG-61463] Fixed a failed assertion that could happen when emitting a
|
||
|
signal from another thread.

-----
|
||
|
|
||
|
- Text:
|
||
|
* [QTBUG-61882] Fixed a bug where mixing different writing systems with
|
||
|
emojis could lead to missing glyphs.
|
||
|
* [QTBUG-65519] Fixed ZWJ and ZWNJ control characters when fallback
|
||
|
fonts are in use.

- QNX:
|

|
* [QTBUG-64033] Fixed the detection of slog2 with QNX 7.0
|
||
|
|
||
|
- Windows:
|
||
|
* Named pipes internally created by QProcess now contain the PID in their
|
||
|
name to ensure uniqueness.
|
||
|
* [QTBUG-65940] Fixed asserts and crashes in QWinEventNotifier.
|
||
|
|
||
|
- WinRT:
|
||
|
* -qdevel and -qdebug are removed from the command line arguments and
|
||
|
not passed to the application.
