Some of the changes listed in this file include issue tracking numbers corresponding to tasks in the Qt Bug Tracker: http://bugreports.qt.nokia.com/ Each of these identifiers can be entered in the bug tracker to obtain more information about a particular change. **************************************************************************** * Source incompatible changes * **************************************************************************** - QSslCertificate::subjectInfo() and QSslCertificate::issuerInfo() now return a QStringList instead of a QString - QSslCertificate::isValid() has been deprecated. Originally it only checked the certificate dates, but later checking for blacklisting was added. Now there's a more specific QSslCertificate::isBlacklisted() method. - Unite clipping support has been removed from QPainter. The alternative is to unite QRegion's and using the result on QPainter. - QLibrary::resolve() now returns a function pointer instead of a void pointer. - QSslCertificate::alternateSubjectNames() is deprecated (but can be enabled via QT_DISABLE_DEPRECATED_BEFORE), use QSslCertificate::subjectAlternativeNames() instead. - QLibraryInfo::buildKey() has been removed. Likewise, the QT_BUILD_KEY preprocessor #define has also been removed. The build-key is obsolete and is no longer necessary. - QCoreApplication::translate() will no longer return the source text when the translation is empty. Use lrelease -removeidentical for optimization. - Qt::escape() is deprecated (but can be enabled via QT_DISABLE_DEPRECATED_BEFORE), use QString::toHtmlEscaped() instead. - QMetaType::construct() has been renamed to QMetaType::create(). - QTestLib: * The QTRY_VERIFY and QTRY_COMPARE macros have been moved into QTestLib. These macros formerly lived in tests/shared/util.h but are now provided by including the header. * The QTEST_NOOP_MAIN macro has been removed from the API. If a test is known at compile-time to be inapplicable for a particular build it should be omitted via .pro file logic, or the test should call QSKIP in the initTestCase() method to skip the entire test and report a meaningful explanation in the test log. * The DEPENDS_ON macro has been removed from the API. This macro did nothing and misled some users to believe that they could make test functions depend on each other or impose an execution order on test functions. * The QSKIP macro no longer has the "mode" parameter, which caused problems for calculating test metrics, as the SkipAll mode hid information about what test data was skipped. Calling QSKIP in a test function now behaves like SkipSingle -- skipping a non-data-driven test function or skipping only the current data row of a data-driven test function. Every skipped data row is now reported in the test log. - The QSsl::TlsV1 enum value was renamed to QSsl::TlsV1_0 . **************************************************************************** * General * **************************************************************************** General Improvements -------------------- - The directory structure of the qtbase unit-tests has been reworked to more closely match the directory structure of the code under test. Integration tests have been moved to tests/auto/integrationtests. Third party components ---------------------- - **************************************************************************** * Library * **************************************************************************** QtCore ------ * drop a bogus QChar::NoCategory enum value; the proper QChar::Other_NotAssigned value is returned for an unassigned codepoints now. QtGui ----- QtWidgets --------- * QWidget::setInputContext() is removed. Input contexts are now platform specific. QtNetwork --------- * QHostAddress::isLoopback() API added. Returns true if the address is one of the IP loopback addresses. * QSslCertificate::serialNumber() now always returns the serial number in hexadecimal format. QtOpenGL -------- QtScript -------- QTestLib -------- * [QTBUG-20615] Autotests can now log test output to multiple destinations and log formats simultaneously. **************************************************************************** * Database Drivers * **************************************************************************** **************************************************************************** * Platform Specific Changes * **************************************************************************** Qt for Linux/X11 ---------------- Qt for Windows -------------- Qt for Mac OS X --------------- Qt for Embedded Linux --------------------- Qt for Windows CE ----------------- **************************************************************************** * Compiler Specific Changes * **************************************************************************** **************************************************************************** * Tools * **************************************************************************** - Build System - Assistant - Designer - Linguist - rcc - moc * [QTBUG-20785] The moc now has a -b option to #include an additional file at the beginning of the generated file. - uic - uic3 - qmake * QMAKE_MOC_OPTIONS variable is now available for passing additional parameters to the moc. - configure - qtconfig **************************************************************************** * Plugins * **************************************************************************** **************************************************************************** * Important Behavior Changes * ****************************************************************************
