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. + +**************************************************************************** +* QtCore * +**************************************************************************** + + - 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. + +**************************************************************************** +* QtWidgets * +**************************************************************************** + + - 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. -- cgit v1.2.3
