| Qt 5.7.1 is a bug-fix release. It maintains both forward and backward |
| compatibility (source and binary) with Qt 5.7.0. |
| |
| 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 5.7 series is binary compatible with the 5.6.x series. |
| Applications compiled for 5.6 will continue to run with 5.7. |

| **************************************************************************** |
| * Important Behavior Changes * |
| **************************************************************************** |
| |
| - [QTBUG-45031] The NSURLConnection backend of QNetworkAccessManager has |
| been removed, since SecureTransport is the default SSL backend on iOS |
| and is enabled by default. This means that building with -no-openssl |
| -no-securetransport will no longer provide SSL capabilities on iOS. |
| |
| - QtCore / QDataStream: |
| * [QTBUG-54022] Incomplete reads of Qt containers are now handled same |
| way as for primitive types, meaning that previous errors are latched. |
| |
| **************************************************************************** |
| * Library * |
| **************************************************************************** |
| |
| QtCore |
| ------ |
| |
| - QLockFile: |
| * Fixed permissions on lock files on Unix to allow for adjustments via |
| umask. |
| |
| - QMimeType: |
| * [QTBUG-50776] QMimeType::comment() now uses the default locale rather |
| than system locale, so that applications can control which language is |
| being used. |
| |
| - QUrl: |
| * QUrl::resolved() no longer treats a URL with a scheme as a relative URL |
| if it matches this URL's scheme. For now it still treats "file:name.txt" |
| as relative for compatibility, but be warned that in Qt 5.8 it will no |
| longer consider those to be relative. Both isRelative() and RFC 3986 say |
| that such URLs are not relative, so starting from Qt 5.8, resolved() will |
| return them as is. |
| |
| - QXmlStreamReader: |
| * Fixed a bug in the XML parser that prevented to load XML that |
| contained invalid characters for XML 1.0. |
| |
| - QXmlStreamWriter: |
| * Fixed a bug that prevented the generation of valid XML files when |
| using encoding with 8 bit per character but not ASCII compatible. |
| QXMLStreamWriter generated XML markup using always ASCII in this case. |
| |
| QtGui |
| ----- |
| |
| - QGuiApplication: |
| * [QTBUG-51703] Fixed a bug that would cause QGuiApplication::sync() to |
| be left undefined for Qt builds without session management support. |
| |
| - QIconLoaderEngine: |
| * Fixed theme lookup for scalable entries |
| |
| - QTextDocument: |
| * [QTBUG-48182] Fixed a bug that would return a wrong position when |
| searching backward from the end of the document. |
| |
| - Text: |
| * [QTBUG-49452] Fixed a performance regression in Freetype engine that |
| was introduced in Qt 5.5. |
| * [QTBUG-53911] Fixed a crash that could happen if you were doing many |
| different text layouts with different fonts and superscript or |
| subscript alignment. |
| * [QTBUG-42033] Fixed bug where a QTextLayout with |
| ShowLineAndParagraphSeparators would modify the layout's input string. |
| * [QTBUG-54180] Fixed performance regression when rapidly switching |
| between a large set of fonts. |
| |
| QtNetwork |
| --------- |
| |
| - QSslSocket: |
| * [QTBUG-55170] Fixed a bug in SecureTransport backend that would cause |
| a memory usage growth in case 'readBufferMaxSize' is set. |
| * [QTBUG-52975] Fixed a bug in SecureTransport backend where transmit |
| was using invalid SSL context and reporting (incorrectly) some irrelevant |
| errors as a result. |
| |
| QtSql |
| ----- |
| |
| - [QTBUG-53969][QTBUG-53237] Fixed QSqlQuery::prepare value truncation |
| error when using UNSIGNED values in a MySQL database. |
| |
| QtWidgets |
| --------- |
| |
| - QAbstractItemDelegate: |
| * [QTBUG-16469] Show localized detailed tooltips and "What's this?" |
| texts. |
| |
| - QTreeView: |
| * [QTBUG-52793] Fixed a key navigation bug when the columns were |
| reordered. |
| |
| **************************************************************************** |
| * Platform-specific Changes * |
| **************************************************************************** |
| |
| Android |
| ------- |
| |
| - [QTBUG-50724] Added support for clang compiler |
| - [QTBUG-53511] Fixed CJK font resolution on Android 7. |
| |
| FreeBSD |
| ------- |
| |
| - The freebsd-g++ mkspec was moved back and no longer requires the |
| "unsupported/" prefix, matching the FreeBSD ports tree, as FreeBSD 9.3 |
| still defaults to using GCC. Users of GCC that did not previously use |
| the ports patch will need to adapt their build scripts and drop the |
| "unsupported/" prefix. |
| |
| Linux |
| ----- |
| |
| - [QTBUG-54733] It is now possible to opt out from installing signal |
| handlers when running with eglfs and linuxfb by setting the |
| QT_QPA_NO_SIGNAL_HANDLER environment variable to a non-zero value. |
| - [QTBUG-55140] xcb with EGL and OpenGL ES, as well as eglfs with the |
| eglfs_x11 backend, are now supported on DRIVE CX boards when using the |
| linux-drive-cx-g++ device spec. |
| |
| |
| Windows |
| ------- |
| |
| - [QTBUG-41186] QWindow::fromWinId() may return 0 when passing invalid |
| window handles. |
| - [QTBUG-55595] Fixed crash when loading color fonts from data. |
| - [QTBUG-55097] Fixed rendering Adobe/Mozilla format color fonts with |
| other colors than black after Windows 10 Anniversary update. |
| - [QTBUG-54494] Fixed stretch when combined with either no or vertical |
| hinting preference or a device pixel ratio different from 1. |
| - [QTBUG-51024] Fixed height of text bounding box when using no or |
| vertical hinting preference, or when the device pixel ratio is |
| different from 1. |
| |

| |
| configure & build system |
| ------------------------ |
| |
| - [QTBUG-35886][QTBUG-51417] Fixed Fontconfig vs. system FreeType |
| configuration. |
| - [QTBUG-43784][X11] Fixed detection of GLX with -qt-xcb. |
| - [QTBUG-51534][Windows] The configure.exe bootstrapping now prefers |
| cl over clang-cl, to avoid header incompatibility problems. |
| - [QTBUG-52940] Fixed missing plugins.qmltypes files in static builds. |
| - [QTBUG-52951] Fixed dynamic library support detection for platforms |
| without libdl. |
| - [QTBUG-53038] Fixed running of configure tests outside qtbase when |
| cross compiling on Windows (for example for Android). |
| - [QTBUG-53312] The flags supplied by the configure -D/-I/-L/-l options |
| are now applied after Qt's own flags. This helps in some cases when |
| the provided paths contain files which conflict with the Qt build. |
| - [QTBUG-53926] Fixed linkage of QML plugins in static prefix builds. |
| - [QTBUG-55011][Unix] Fixed -no-pkg-config being ignored by some |
| configure tests, which led to build failures later on. |
| - Fixed configure tests outside qtbase when $MAKEFLAGS contains the |
| -i flag. |
| - [Android] Some unused plugins are not built anymore. |
| - [MinGW] Added support for -separate-debug-info. |
| - [Unix] Added configure -no-opengles3 option. |
| - [Unix] Fixed MySQL detection/use on RHEL 6.6. |
| |
| qmake |
| ----- |
| |
| - [QTBUG-41830] Fixed nested custom functions inheriting their callers' |
| arguments. |
| - [QTBUG-53895][MSVC] Started using separate PDB files for compiling |
| and linking. |
| - [QTBUG-54036][Darwin] Fixed installation of debug symbols. |
| - [QTBUG-54299] Various QMAKE_EXTRA_COMPILERS' .depends entries are now |
| appended to rather than overwritten. |
| - [QTBUG-54346][MSys/Apple] Fixed detection of QMAKE_DEFAULT_{INC,LIB}DIRS. |
| - [QTBUG-54550] Fixed access to freed memory in $$absolute_path(). |
| - [QTBUG-54674] The obsolete -target xp is now properly rejected. |
| - [QTBUG-55183][nmake] _WINDLL is now automatically defined when building |
| a DLL, consistently with Visual Studio. |

| path against static builds of Qt. |
| - [QTBUG-55649][QTBUG-55915][Xcode] Fixed support for Xcode 8. |
| - [QTBUG-56162][MinGW] Fixed -release -force-debug-info missing both |
| optimization and debug info. |
| - Fixed several cases where the error() function would not abort qmake. |
| - Interrupting a command run via system() will now abort qmake as well. |
| - The packagesExist() function will now warn when used when Qt was |
| configured with -no-pkg-config. |
| - [Android] The default compiler flags were adjusted to match newer |
| NDK versions. |
| - [Darwin] Fixed detection of QMAKE_DEFAULT_INCDIRS. |
| - [Darwin][make] Added support for building Xcode asset catalogs. |
