| Qt 5.13 introduces many new features and improvements as well as bugfixes | ||
| over the 5.12.x series. For more details, refer to the online documentation | ||
| included in this distribution. The documentation is also available online: | ||
|
|
||
| https://doc.qt.io/qt-5/index.html | ||
|
|
||
| The Qt version 5.13 series is binary compatible with the 5.12.x series. | ||
| Applications compiled for 5.12 will continue to run with 5.13. | ||

| **************************************************************************** | ||
| * Important Source Incompatible Changes * | ||
| **************************************************************************** | ||
|
|
||
| - Moc generated files include the standard <memory> header file now. | ||
| A side effect of this is that code including the Moc output from within | ||
| a namespace will fail to compile. | ||
|
|
||
| **************************************************************************** | ||
| * Important Behavior Changes * | ||
| **************************************************************************** | ||
|
|
||
| - The Qt resource system now supports compressing content using the | ||
| Zstandard (https://zstd.net) algorithm. Compared to zlib, it compresses | ||
| better for the same CPU time, so this algorithm is the default. | ||
| QResource::isCompressed() returns true for either compression algorithm. | ||
| Use QResource::compressionAlgorithm() to find out which algorithm to | ||
| decompress. QFile will automatically decompress using the correct | ||
| algorithm. | ||
|
|
||
| - QDataStream version bumped up to 19 to account for changes in the | ||
| serialization of QFont. | ||
|
|
||
| - [QTBUG-73048] Qt now enables by default warnings when using APIs | ||
| marked as deprecated. It is possible to disable such warnings by | ||
| defining the QT_NO_DEPRECATED_WARNINGS macro. The old | ||
| QT_DEPRECATED_WARNINGS macro which was used to enable this warning | ||
| now has no effect (warnings are automatically enabled). | ||
|
|
||
| **************************************************************************** | ||
| * Third-Party Code * | ||
| **************************************************************************** | ||
|
|
||
| - Updated bundled SQLite to version 3.27.1. | ||
| - [QTBUG-72623] Updated DNS public suffix list | ||
| - [QTBUG-73883] libjpeg-turbo was updated to version 2.0.2 | ||
| - Bundled libpng was updated to version 1.6.37 | ||
|
|
||
| **************************************************************************** | ||
| * Platform-Specific Changes * | ||
| **************************************************************************** | ||
|
|
||
| - X11 / XCB: | ||
| * [QTBUG-45375] QTabletEvent coordinates now come from AbsX/AbsY | ||
| valuators in the X11 event, in more precise 32.32 fixed-point format, | ||
| scaled to fit the virtual desktop. It's possible to revert to using | ||
| the legacy 16.16-format event_x/event_y coordinates as in previous | ||
| releases by setting the QT_XCB_TABLET_LEGACY_COORDINATES environment | ||
| variable. | ||
| * [plugins] platforminputcontexts now use libxkbcommon-compose APIs for | ||
| compose key input, instead of Qt's own implementation. | ||
|
|
||
| - Android | ||
| * Increased the minimum supported Android version to Android 5.0 | ||
| (API level 21). | ||
|
|
||
| - Windows | ||
| * [QTBUG-47247][QTBUG-71855] Add a default setting for | ||
| hasBorderInFullScreen in QtPlatformHeaders, QWindowsWindowFunctions | ||
| * [QTBUG-57180] Removed confusing DirectWrite warning when loading | ||
| bitmap fonts. | ||
|
|
||
| - macOS | ||
| * Accessibility: VoiceOver now reads all lines in multiline text | ||
| components when navigating by lines. | ||
|
|
||
| **************************************************************************** | ||
| * Tools * | ||
| **************************************************************************** | ||
|
|
||
| - configure & build system: | ||
| * Added --linker=[bfg,lld,gold] configure flag. | ||
| * The default OpenGL configuration changed from ANGLE to dynamic OpenGL. | ||
| * Added -schannel option to enable Schannel support on Desktop Windows. | ||
| * Added -coverage option for recording coverage data during execution | ||
|
|
||
| - CMake | ||
| * Added support for automatic linking of transitive dependencies in | ||
| static builds | ||
|
|
||
| - qmake | ||
| * [QTBUG-53654] Introduced the variables WINDOWS_TARGET_PLATFORM_VERSION | ||
| and WINDOWS_TARGET_PLATFORM_MIN_VERSION for overriding the default | ||
| values of WindowsTargetPlatformVersion and | ||
| WindowsTargetPlatformMinVersion in Visual Studio project files. | ||
|
|
||
| - RCC now supports compressing content using the Zstandard | ||
| (https://zstd.net) algorithm. Compared to zlib, it compresses better for | ||
| the same CPU time, so this algorithm is the default. To go back to the | ||
| previous algorithm, pass command-line option --compress-algo=zlib. | ||
| Compression levels range from 1 (fastest, least compression) to 19 | ||
| (slowest, best compression). Level 0 tells the library to choose an | ||
| implementation-defined default. The default compression level is | ||
| "heuristic" (level -1): under this mode, RCC will attempt a very fast | ||
| compression (level 1) and check if the file was sufficiently compressed. | ||
| If it was, then RCC will compress again using an implementation-defined | ||
| level. | ||

|
||
| - New class QConcatenateTablesProxyModel, to concatenate the rows from | ||
| multiple source models. | ||
| - New class QTransposeProxyModel to swap rows and columns of the source | ||
| model. | ||
| - Added macros Q_DISABLE_MOVE and Q_DISABLE_COPY_MOVE complementing | ||
| Q_DISABLE_COPY. | ||
| - Qt Containers and meta type system now use C++11 type traits | ||
| (std::is_trivial, std::is_trivially_copyable and | ||
| std::is_trivially_destructible) to detect the class of a type not | ||
| explicitly set by Q_DECLARE_TYPEINFO. (Q_DECLARE_TYPEINFO is still | ||
| needed for QList.) | ||
|
|
||
| - QCommandLineParser: | ||
| * [QTBUG-58490] The application name (if set in QCoreApplication) is now | ||
| shown in error messages. | ||
|
|
||
| - QDateTime: | ||
| * [QTBUG-71030] Fixed race conditions in getting the local time zone. Qt now | ||
| has a mutex lock around all calls to tzset() and mktime(). Application | ||
| code should avoid calling those functions directly. | ||
|
|
||
| - QFile: | ||
| * Made QFile::copy() issue a filesystem-synchronization system call, | ||
| which would make it less likely to result in incomplete or corrupt | ||
| files if the system reboots or uncleanly shuts down soon after the | ||
| function returns. New code is advised to use QSaveFile instead, which | ||
| also allows display of a progress report while copying. | ||
|
|
||
| - QFileInfo: | ||
| * [QTBUG-63970][QTBUG-30401][QTBUG-20791] Fixed resolving of symbolic | ||
| links to UNC shares on NTFS file systems. | ||
|
|
||
| - QJsonArray: | ||
| * [QTBUG-32793] Added cbegin() and cend() methods for compatibility with | ||
| the Standard Library container concepts. | ||
|
|
||
| - QJsonDocument: | ||
| * [QTBUG-71445] Added the ability to stream QJsonDocument into and from | ||
| QDataStream if it is contained in a QVariant. | ||
|
|
||
| - QLocale: | ||
| * Added support for Western Balochi, Ido, Lojban, Sicilian and | ||
| Southern Kurdish. | ||
| * [QTBUG-71445] Added a const overload for formattedDataSize(). | ||
| * [QTBUG-782] Added toLong() and toULong(). | ||
|
|
||
| - QMetaObject: | ||
| * Non-copyable lambdas can now be used with invokeMethod(). For | ||
| consistency reasons, the functor object is now always moved. | ||
|
|
||
| - QMimeDatabase: | ||
| * Added configure option -no-mimetype-database that tells Qt not to | ||
| bundle its own copy of the XDG MIME database. If this option is | ||
| passed, QMimeDatabase will only work if there's a system copy in | ||
| $XDG_DATA_DIRS/mime. This option is useful for Linux distributions | ||
| that ensure the data is always present. | ||
|
|
||
| - QSettings: | ||
| * Added QSettings(Scope...) constructor to avoid using #ifdef in Qt | ||
| applications. | ||
|
|
||
| - QStringListModel: | ||
| * [QTBUG-69807] Implemented moveRows | ||
|
|
||
| - QUrlQuery: | ||
| * QUrlQuery now provides an initializer list constructor. It can be | ||
| created using a list of key/value pairs. | ||
|
|
||
| - QVector: | ||
| * QVector no longer requires a default constructor for its template | ||
| argument. | ||
|
|
||
| **************************************************************************** | ||
| * QtDBus * | ||
| **************************************************************************** | ||
|
|
||
| - Matching namespace prefixes using QDBusServiceWatcher (instead of full | ||
| service names) is now possible. For example, "com.example.backend1*" | ||
| will match "com.example.backend1", "com.example.backend1.foo" and | ||
| "com.example.backend1.foo.bar", but not "com.example.backend12". | ||
|
|
||
| **************************************************************************** | ||
| * QtGui * | ||
| **************************************************************************** | ||
|
|
||
| - CSS: | ||
| * Added support for HSL/HSLA colors. | ||
| * Fix the range of the hue parameter when parsing a color given in HSL | ||
| or HSV. | ||
|
|
||
| - QFont: | ||
| * Add setFamilies()/families() to support use of font families with | ||
| commas and quotes in their name. | ||
|
|
||
| - QImage: | ||
| * [QTBUG-41176] Added support for 16-bit grayscale format. | ||
| * A new method convertTo has been added to change the format of a QImage | ||
| in place. | ||
|
|
||
| - QPainterPath: | ||
| * Added clear(), reserve(), capacity(). clear() removes allocated | ||
| QPainterPath elements but preserves allocated memory, which can be | ||
| useful for application with complex paths that are often recreated. | ||
| reserve() and capacity() follow QVector semantics. | ||
|
|
||
| - QWindow: | ||
| * [QTBUG-67903][QTBUG-52944] QWindow::transientParent is now a property. | ||
|
|
||
| - Text: | ||
| * [QTBUG-60813] Deprecated QFont::lastResortFamily() and | ||
| QFont::lastResortFont() which are not in use in Qt 5 and did not | ||
| provide any useful information. | ||
| * [QTBUG-22813] Added support for setting the font's style name in | ||
| QTextCharFormat. | ||
|
|
||
| **************************************************************************** | ||
| * QtNetwork * | ||
| **************************************************************************** | ||
|
|
||
| - TLS (SSL): | ||
| * Support for SSLv2 and SSLv3 sockets has been dropped, as per RFC 6176 | ||
| (2011) and RFC 7568 (2015). | ||
| * The Schannel backend now supports ALPN and thus HTTP/2. | ||
| * [QTBUG-62637] Added support for Schannel on Desktop Windows. To build | ||
| Qt with Schannel support use '-schannel' during configure. | ||
| * Added class QOcspResponse as a part of OCSP stapling support. | ||
| * [QTBUG-12812][QTBUG-17158] Added OCSP-stapling support for OpenSSL | ||
| backend | ||
| * [QTBUG-71828][QTBUG-73289] Fixed SSL verification when connecting to IP | ||
| address (no host name) if that IP address is listed in the certificate. | ||
|
|
||
| **************************************************************************** | ||
| * QtTestLib * | ||
| **************************************************************************** | ||
|
|
||
| - Added QTest::toString(const QModelIndex &idx) | ||
|
|
||
| - Removed support for GPU_BLACKLIST files. Reimplementations or | ||
| equivalents of QTEST_MAIN() should remove their uses of | ||
| QTEST_ADD_GPU_BLACKLIST_SUPPORT and its _DEFS; they are still vacuously | ||
| defined, but serve no remaining purpose and shall be undefined in due | ||
| course. | ||

|
|
||
| - QAbstractScrollArea: | ||
| * [QTBUG-69120] QTableView/QTreeView, when reporting their | ||
| viewportSizeHint(), now correctly take into account their scroll | ||
| bars' visibility and visibilityPolicy. | ||
|
|
||
| - QHeaderView: | ||
| * dataChanged now respects the given roles to avoid useless | ||
| recomputations. | ||
|
|
||
| - QLabel: | ||
| * Minor performance improvement when painting a label with an image. | ||
|
|
||
| - QListWidget: | ||
| * [QTBUG-69807] Implemented moveRows in model | ||
| * [QTBUG-68977] Sped up handling of hidden items when working with large | ||
| data sets. | ||
|
|
||
| - QPlainTextEdit: | ||
| * Added QRegularExpression find() method overload. | ||
|
|
||
| - QTextEdit: | ||
| * Added QRegularExpression find() method overload. | ||
|
|
||
| - QTreeView: | ||
| * Added expandRecursively() to expand all items below a given index. | ||
|
|
||
| - QWidgetTextControlPrivate: | ||
| * [QTBUG-69735] Moved cursor selection to start. | ||
|
|
||
| **************************************************************************** | ||
| * QtSql * | ||
| **************************************************************************** | ||
|
|
||
| - SQLite: | ||
| * [QTBUG-63498] The json1-extension for the SQLite3 plugin is now enabled | ||
| by default. | ||
|
|
||
| - PostgreSQL: | ||
| * QSqlDatabase is now stricter about table names when used with record() | ||
| and primaryIndex(). If the tablename was not quoted when it was | ||
| created, then the table name passed to record() and primaryIndex() | ||
| needs to be in lower case so that PostgreSQL is able to find it. |
