Qt 5.9.2 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.
|
|
|
|
Some of the changes listed in this file include issue tracking numbers
|
|
corresponding to tasks in the Qt Bug Tracker:

* Important Behavior Changes *
|
|
****************************************************************************
|
|
|
|
- Building examples inside the Qt source tree while not building Qt itself
|
|
is rejected now, because this can cause hard to debug configuration
|
|
issues. If building isolated examples is needed, you may still use shadow
|
|
builds.
|
|
|
|
- This version of Qt restores compatibility with pre-5.9.0 calculation of
|
|
QCryptographicHash algorithms that were labelled "Sha3_nnn": that is,
|
|
applications compiled with old versions of Qt will continue using the
|
|
Keccak algorithm. Applications recompiled with this version will use
|
|
SHA-3, unless QT_SHA3_KECCAK_COMPAT is #define'd prior to #include
|
|
<QCryptographicHash>.

Binary Compatibility Note
|
|
-------------------------
|
|
|
|
- The variable QOperatingSystemVersion::AndroidOreo was added in this
|
|
release. Code that uses this variable will not run under Qt 5.9.1. If
|
|
backwards compatibility is desired, use instead
|
|
QOperatingSystemVersion(QOperatingSystemVersion::Android, 8)
|
|
[This is similar to QOperatingSystemVersion::MacOSHighSierra added in
|
|
5.9.1]
|
|
|
|
- This version of Qt changes the values assigned to enumerations
|
|
QCryptographicHash::Sha3_nnn. Applications compiled with this version and
|
|
using those enumerations will not work with Qt 5.9.0 and 5.9.1, unless
|
|
QT_SHA3_KECCAK_COMPAT is defined.
|
|
|
|
Deprecation Notice
|
|
------------------
|
|
|
|
- Starting with Qt 5.10, IPv6 support will be mandatory for all platforms.
|
|
Systems without proper IPv6 support, such as the getaddrinfo() function
|
|
or the proper socket address structures, will not be able to build
|
|
QtNetwork anymore.
|
|
|
|
Third-Party Code
|
|
----------------
|
|
|
|
- [QTBUG-31020] zlib was updated to version 1.2.11.
|
|
- libpng was updated to version 1.6.32

|
|
QtCore
|
|
------
|
|
|
|
- [QTBUG-61350] Fixed the conversion from string to double of the strings
|
|
"0E+1" and "0E-1" (with capital E), which QString::toDouble(),
|
|
QByteArray::toDouble() and similar functions reported as invalid.
|
|
|
|
- QFile:
|
|
* [QTBUG-57023] Reverted an incorrect change from Qt 5.9.0 that forbade
|
|
the creation and access to Alternate Data Streams on NTFS on Windows.
|
|
This means that file names containing a colon (':') are allowed again,
|
|
but note that they are not regular files.
|
|
|
|
- QFileInfo:
|
|
* [QTBUG-62802] Relative symbolic links on Windows are now resolved to
|
|
their absolute path by symLinkTarget().
|
|
|
|
- QFileSystemWatcher:
|
|
* [QTBUG-62242] Fixed a crash on Windows if this class was instantiated
|
|
before QCoreApplication was created.
|
|
* [QTBUG-61792] Fixed an issue on Windows that would cause this class not
|
|
to monitor files properly if the directory containing the monitored
|
|
files was added to the list of watched paths after the files.
|
|
|
|
- QLocale:
|
|
* [QTBUG-53565] Fixed the conversion of QTime to string form and parsing
|
|
from string form to always treat the value as the decimal fraction of
|
|
the seconds component. That is, the string format ".z" produces/parses
|
|
".2" for 200 milliseconds and ".002" for 2 milliseconds. Use of "z" or
|
|
"zzz" is discouraged outside decimal fractions to avoid surprises.
|
|
* [QTBUG-61949] Fixed bcp57Name() to return "en" for the QLocale::c()
|
|
locale. Previously, it returned "C", which is not a valid BCP47
|
|
language tag.
|
|
|
|
- QProcess:
|
|
* [QTBUG-61634] Added a workaround for a rare race-condition bug in
|
|
some C libraries that caused the child process started by QProcess to
|
|
hang after trying to launch a non-existent executable or change to a
|
|
non-existent directory.
|
|
* [QTBUG-62584] Fixed a race-condition bug that could cause
|
|
waitForXxx() functions to hang forever if a slot triggered by that
|
|
function futher started a nested event loop.
|
|
|
|
- QTimeZone:
|
|
* [QTBUG-63205] Fixed a bug that would cause QTimeZone to mis-parse
|
|
timezone files on Unix systems if they contained leap second
|
|
information.
|
|
|
|
- QVariant:
|
|
* [QTBUG-61471] Fixed QVariant to actually perform the conversions
|
|
between QVariantHash and QVariantMap in the respective .toHash() and
|
|
.toMap() functions. QVariant already reported true in .canConvert()
|
|
between those two types.
|
|
|
|
QtDBus
|
|
------
|
|
|
|
- [QTBUG-62284] Fixed a race condition in QDBusAbstractInterface that
|
|
could cause the class to never see the notification that the remote
|
|
service became available and cause isValid() to change to true.
|
|
|
|
QtGui
|
|
-----
|
|
|
|
- Text:
|
|
* [QTBUG-61520] Fixed matching of non-regular font weights for
|
|
application fonts on macOS.
|
|
|
|
QtNetwork
|
|
---------
|
|
|
|
- [QTBUG-61692] Fixed the handling of application-wide proxy settings (set
|
|
with QNetworkProxy): previously, QTcpSocket would directly fall back to
|
|
the system settings if the object-specific setting was
|
|
QNetworkProxy::DefaultProxy.
|
|
|
|
- QLocalSocket:
|
|
* [QTBUG-61643] Fixed an issue with Qt pipe-handling code that could
|
|
cause deadlocks on Windows, most often if the QLocalSocket object tried
|
|
to wait for more data during application shutdown.
|
|
|
|
QtTest
|
|
------
|
|
|
|
- Added flowId to messages when logging in TeamCity format. FlowId is used
|
|
to distinguish logging from multiple processes running in parallel.
|
|
|
|
QtWidgets
|
|
---------
|
|
|
|
- Android:
|
|
* [QTBUG-48639] Fixed label duplication for buttons when using style
|
|
sheets with the Android style.
|
|
|
|
- QLineEdit:
|
|
* [QTBUG-60319] Fixed behavior of the ImSurroundingText query.
|
|
Previously, it returned a masked text whose length may be less than
|
|
the cursor position. Now it returns unmasked text, so the text length
|
|
is always greater than or equal to the cursor position.
|
|
|
|
- QMenu:
|
|
* [QTBUG-59794] Fixed menu size issue when using high DPI on
|
|
multi-screen system.

clang
|
|
-----
|
|
|
|
- [QTBUG-61840][QTBUG-62085] Fixed an issue that caused recent Clang
|
|
versions to print a warning about [[nodiscard].
|
|
|
|
Visual Studio
|
|
-------------
|
|
|
|
- [QTBUG-61902] Changed Qt uses of certain C++ Standard Library functions
|
|
that Visual Studio warns about. Now Qt public headers call
|
|
Microsoft-specific versions that do not produce warnings.

macOS
|
|
-----
|
|
|
|
- [QTBUG-59222] Switching focus objects inside a top level window while
|
|
composing text using dead keys or input method events would leave the
|
|
application in an inconsistent state. The composition now automatically
|
|
cancels when the focus object changes.
|
|
|
|
Windows
|
|
-------
|
|
|
|
- [QTBUG-57916] Fixed build with ANGLE and newer MinGW versions.
|
|
- [QTBUG-62083] Fixed Qt trying to steal certain events from user windows if
|
|
the event ID was WM_USER.

|
------------------------
|

|
|

|
|
- [X11] Fixed detection of x11-xcb with pkg-config.
|
|
- [CMake] All Qt module defines are now propagated to the config files.

|
|

- [QTBUG-61411][Windows] _UNICODE is now defined, consistently with VS.
|
|
- [QTBUG-61688][MSVC] Fixed compilation of precompiled headers with
|
|

- [QTBUG-61690][QTBUG-61735] Fixed detection of compiler default search
|
|
