Also, there is a change in the licensing terms. +For more details, refer to the online documentation included in this +distribution. The documentation is also available online: + + http://doc.qt.io/qt-5.7 + +The Qt version 5.7 series is binary compatible with the 5.6.x series. +Applications compiled for 5.6 will continue to run with 5.7. + +Some of the changes listed in this file include issue tracking numbers +corresponding to tasks in the Qt Bug Tracker: + + http://bugreports.qt.io/ + +Each of these identifiers can be entered in the bug tracker to obtain more +information about a particular change. + +This release contains all fixes included in the Qt 5.6.1 release. + +**************************************************************************** +* Important License Changes * +**************************************************************************** + + - Qt is no longer available under LGPLv2.1. The libraries in this package + are now available under the following licenses: + * Commercial License + * GNU General Public License v2.0 (LICENSE.GPL2) and later + * GNU Lesser General Public License v3.0 (LICENSE.LGPL3) + + Note that a few Qt Libraries (currently Qt Charts and Qt Data + Visualization) are available only under the Commercial License and GPL + version 3. + + - Qt Tools are now available under the following licenses: + * Commercial License + * GNU General Public License 3.0 (LICENSE.GPL3) with exceptions + described in the Qt Company GPL Exception 1.0 (LICENSE.GPL3-EXCEPT) + +**************************************************************************** +* Important Behavior Changes * +**************************************************************************** + + - Starting with Qt 5.7, Qt requires a C++11 compiler with support for + C++11 atomics. This affects user code too: Qt headers no longer compile + with a C++98 compiler. The minimum compiler versions for this release + are: + * GCC 4.7 + * Clang 3.4 (found in XCode 5.1) + * Microsoft Visual Studio 2013 + - Support for the following platforms was removed in this version: + * Apple OS X 10.7 (Lion) + * Microsoft Windows XP + * Microsoft Windows Vista + * Microsoft Windows Embedded Compact 7 + * Microsoft Windows Embedded Compact 2013 + - Support for DirectFB is no longer enabled by default, due to lack of + development in upstream. To re-enable the platform plugin, pass the + -directfb option to configure. If there is no renewed interest in this + platform, the support will be removed in Qt 5.8. + - Qt no longer ships any fonts. + + - QtGui: + * [QTBUG-51962] When line height is specified in pixels, this is now + interpreted as the minimum line height rather than an absolute line + height to avoid overlaps. To get the old behavior, use the + -qt-line-height-type property in CSS and set it to "fixed". + * [QTBUG-46054] QFont::exactMatch() now returns false when the provided + typeface is an alias. + + - QtWidgets: + * [QTBUG-21217] QLineEdit will now accept certain shortcut override + events even if it is read-only. + + - configure & build system: + * Except on OS X, -system-harfbuzz is now the default. + * A few obsolete options with no effect are not recognized any more. + +**************************************************************************** +* Deprecation Notice * +**************************************************************************** + + - The following platforms or toolchains are deprecated and will be + removed as of Qt 5.8: + * Apple OS X 10.8 (Mountain Lion) + + Deprecated platforms and toolchains continue to work until removed. + +**************************************************************************** +* Library * +**************************************************************************** + +QtCore +------ + + - [QTBUG-50548] Added qAsConst(). + - Added qOverload() to select overloaded functions. + - Added qHash(std::pair), defined in . + - Added qUtf16Printable(). + - QLocale data updated to CLDR v29 + + - QDataStream: + * [QTBUG-44418] Added startTransaction(), commitTransaction(), + rollbackTransaction(), abortTransaction() functions to support read + transactions. + + - QDebug: + * QDebug can now output std::vector, std::list, std::map, and + std::multimap. + + - QFlags: + * [QTBUG-27100] Added setFlag method to set or unset a flag + + - QHash/QSet: + * Added QHash::equal_range(). + * Added erase(const_iterator). + + - QIODevice: + * Added support for devices with multiple streams. + * [QTBUG-44418] Added startTransaction(), commitTransaction(), + rollbackTransaction(), isTransactionStarted() functions to support + read transactions. + + - QJsonObject: + * Added value(), op[] const, find(), constFind(), contains() overloads + taking QLatin1String. + + - QLocale: + * Added special value for double conversion precision to get shortest + accurate representation. + * Added additional flags in QLocale::NumberOption that allow generating + and parsing doubles in EcmaScript compliant format. + * [QTBUG-46595] Added an overload for toCurrencyString() that allows the + decimal precision to be specified. + + - QMutex: + * Made the isRecursive() method be a const function so that it can be + called in const QMutex objects too. + + - QObject: + * [QTBUG-52542] If the compiler supports variadic templates, functors + connected to signals will not be copied any more each time the signal is + emitted. This is the behavior that was exhibited with C++98 compilers. + + - QReadWriteLock: + * Optimized QReadWriteLock to be faster and take less memory. + + - QRect: + * Fixed integer overflow in center(). This fixes the result for some + corner-cases like a 1x1 rectangle at (INT_MIN, INT_MIN), for which the + previous implementation could return anything (due to invoking + undefined behavior), but commonly returned (0, 0). + + - QRect/QRectF: + * Added transposed(). + + - QSharedPointer: + * Added support for debug printing via QDebug. + + - QStorageInfo: + * [QTBUG-49498] Fixed a bug that caused QStorageInfo to report + information for the wrong filesystem if there is a mounted filesystem + at a path that is a prefix of the requested path (e.g., it would + report "/usr" filesystem for "/usrfoo"). + + - QString: + * Added resize(int, QChar) overload. + + - QStringRef: + * Added subscript operator. + * Fixed relational operators against (const char*) to return the correct + result. + * Added reverse iterators, rbegin(), rend(), crbegin(), crend(). + + - QUuid: + * Added Objective-C NSUUID/CFUUIDRef converters. + + - QVariant: + * [QTBUG-53384] Fixed QVariant::canConvert and conversion from integer + types to enumeration types. + + - QVector: + * clear() now preserves capacity. To shed capacity, call squeeze() or + swap with a default-constructed QVector object, see the documentation + for an example. + + - State Machine: + * Added constructor overload that takes a pointer-to-member for the + QSignalTransition. + +QtDBus +------ + + - QDBusArgument: + * [QTBUG-53376] Deprecated relying on a streamable Base to stream a + Derived without providing operator<>() for Derived. No diagnostic + provided. Support will be removed in Qt 5.8. + +QtGui +----- + + - QWheelEvent::phase() now returns NoScrollPhase with non-phase-aware mice. + This is most mice and input devices except, for now, Apple's trackpads + and Magic Mouse. It is no longer necessary to set the + QT_ENABLE_MOUSE_WHEEL_TRACKING environment variable to enable the fix for + QTBUG-50199. + - [QTBUG-35972] Added QWheelEvent::inverted() to enable detection of the + "natural scrolling" system setting. This feature currently only works on + OS X, though support for other operating systems is planned. + + - Image: + * [QTBUG-50745] Fixed possible crash in QImage::pixel() for mono or + indexed images. + + - QIcon: + * Split fromTheme() in two different overloads, one of which will only + lazily lookup the icons, in order to speed up startup of applications + that initialize many icons that are not necessarily visible. + * fromTheme gained the ability to use the GTK icon cache to speed up + lookups. + + - QPixmapCache: + * Added QPixmapCache::Key::isValid(). + + - QRawFont: + * Fixed kerning on advances in QRawFont for OS X and Windows. + + - Tablet support: + * [QTBUG-47007][QTBUG-51618] A synthetic mouse event will no longer be + sent after every QTabletEvent, only after those which are not accepted + (as documented). + + - Text: + * [QTBUG-35156] Added support for color font rendering with Freetype. + * [QTBUG-52048] Added QTextOption::ShowDocumentTerminator flag. + +QtNetwork +--------- + + - QAuthenticator: + * [QTBUG-53338] Fixed crash when comparing a initialized QAuthenticator + with an uninitialized QAuthenticator. + +QtWidgets +--------- + + - Moved QGtkStyle to the qtstyleplugins repository. + - [QTBUG-37580] Added the Qt::AA_UseStyleSheetPropagationInWidgetStyles + attribute which enables font and palette propagation for Qt Style + Sheets. + - [QTBUG-48138] QPinchGesture on OS X now behaves like on other platforms: + totalScaleFactor is the magnitude of the pinch and scaleFactor is the + delta for the current event. + + - Item Views: + * [QTBUG-50102] Item views scroll per pixel on OS X now. + * [QTBUG-50102] QAbstractItemView::verticalScrollMode and + QAbstractItemView::horizontalScrollMode are now resettable. + + - QAbstractItemView: + * [QTBUG-7232] In ItemViews when scrollMode is set to scrollPerPixel, it + is now possible to change the single step. Qt will automatically adjust + the single step until setSingleStep is called. When setSingleStep is + called it will however respect that and stop doing automatic changes + of the value. Calling setSingleStep(-1) will switch mode back to + automatic adjusting. + + - QAbstractScrollArea, QTextEdit, QPlainTextEdit: + * [QTBUG-52559] Changed focus to Qt::StrongFocus. That respects + platforms' native guidelines. + + - QHeaderView: + * [QTBUG-39010] Fixed some issues with restoring of section size after a + section is no longer the last visible section (in stretchLastSection + mode). + * [QTBUG-50171] Fixed a repainting issue when items had been reordered. + + - QListWidget: + * [QTBUG-15741] Fixed a bug that caused the default drop action to be + ignored when using icon mode. + + - QTableView: + * [QTBUG-50171] Fixed a selection bug when rows or columns were hidden. + + - Styles: + * [QTBUG-50102] Added SH_ItemView_ScrollMode style hint. + + - Dialogs: + * [QTBUG-51148] Fixed requesting a font from font dialog with a + non-existent family name and/or pixel size when using GTK2 platform + theme. + +QTest +----- + + - Added a new logging mode that allow test-results to be parsed on-the-fly + when using Jetbrains TeamCity as CI-server. This mode is enabled by + using the -teamcity option on the command-line. + +**************************************************************************** +* Platform-specific Changes * +**************************************************************************** + + - The Gtk+ platform theme has been ported to Gtk+ 3. + - Dropped support for Windows CE. + - Added support for INTEGRITY RTOS. + +Android +------- + + - Support for Android API < 16 was removed. + - [QTBUG-37221] Qt can now be used to easily create Android Services. + - Allow the user to choose how much from the Android theme is extracted. + +iOS +--- + + - [QTBUG-35271] QBackingStore now uses the raster paint engine instead of + the OpenGL paint engine, enabling improved antialiased drawing. In case + of performance regressions, the old code path can be enabled by setting + the window's surface type to QSurface::OpenGLSurface. + +OS X +---- + + - Support for OS X < 10.8 was removed. + - [QTBUG-7000] QMacPrintEngine now really sets the printer resolution. + - [QTBUG-32898] OS X now accepts trusted certificates from the login and + system keychains. + - [QTBUG-48953] Pasting text from Qt applications to Apple Mail now works. + - [QTBUG-48953] "text/vcard" is now required as the mime type when + placing vCards on the clipboard. + - [QTBUG-50262] QStandardPaths now returns the correct display name for + the download folder. + +Windows +------- + + - [QTBUG-390][QTBUG-6917][QTBUG-9350][QTBUG-24619] Added method + QProcess::setCreateProcessArgumentsModifier() to enable users to + intercept and modify CreateProcess parameters. + - Added support for color fonts (color emojis) when DirectWrite 2 is + available. + + - Text: + * [QTBUG-47141] Made it possible to disable antialiasing for text when + drawing into images. + * [QTBUG-18711] Fixed disabling hinting for application fonts, e.g. when + automatic scaling by device pixel ratio is in effect. + +XCB / X11 +--------- + + - [QTBUG-44964] It's now possible to unset AA_CompressHighFrequencyEvents + to disable the new X event compression feature that was added in 5.6.0. + This is a replacement for the WA_NoX11EventCompression flag in Qt 4. + - [QTBUG-49071] Fixed failure to deliver focusIn event on hide/show with XCB + - QMenuBar now uses the unified D-Bus AppMenu menubar when the desktop + environment supports it. + +**************************************************************************** +* Tools * +**************************************************************************** + +moc +--- + + - [QTBUG-53441] Fixed crash when processing files ending with \\\r. + +configure & build system +------------------------ + + - [QTBUG-35754] Static builds now embed QML resources into the libraries + to make them self-contained. + - [QTBUG-35886][Unix] Made it explicit that -fontconfig implies + -system-freetype. + - [QTBUG-43784][Unix] Fixed GLX not being enabled with -qt-xcb. + - [QTBUG-45291][GCC] Enabled use of Qt with -Wzero-as-null-pointer-constant. + - [Android@Windows] Fixed configure tests outside QtBase. + - [Unix] Fixed config.log corruption with option -v. + - [Unix] Fixed the MySQL configure test on RHEL 6.6. + - [Android] Enabled building with newer SDKs than the minimal supported one. + - QNX and Android builds on Windows use -system-zlib now. + - Added support for "Canadian Cross Builds"; options -external-hostbindir + and -host-option. + - Added makespecs for DRIVE CX (Tegra X1), NVIDIA Jetson TK1, and i.MX7 + boards. + - Qt now makes use of AVX512 instructions on Intel platforms. + +qmake +----- + + - Specifying directories in RESOURCES now actually works. + - Added -qtconf option to make it possible to use the same qmake binary + with several builds of Qt. -- cgit v1.2.3
