Code optimized for Neon must be enabled + unconditionally at compile time by ensuring the compiler supports + Neon. You may need to edit your mkspec for that. + + * Qt now automatically generates code for processors supporting SSE2 + on i386 platforms. To disable this, pass the -no-sse2 option during + Qt configuration. Since this feature has been present on CPUs for + 10 years and since Qt no longer checks for runtime support for + SSE2, we strongly encourage users to leave the default setting on + for best performance. + - For Linux distributions that must retain support for CPUs without + SSE2, we recommend doing two builds of Qt and installing the + SSE2-enabled libraries in the LIBDIR/sse2 directory (specially + QtGui, QtQml and QtQuick libraries). Tools, plugins, and examples + are not affected. + - See discussion on the Qt development mailing list: + http://lists.qt-project.org/pipermail/development/2013-November/014085.html + + - SSL and security: + * The default set of ciphers used by QSslSocket has been changed to + exclude ciphers that are using key lengths smaller than 128 + bits. These ciphers are still available and can be enabled by + applications if required. + * [QTBUG-20666] Support for DH and ECDH key exchange cipher suites + when acting as an SSL server has been made possible. This change + means the you can now implement servers that offer forward-secrecy + using Qt. + * Running Qt applications that are setuid is no longer allowed by + default. If you really need to do this then you can call + QCoreApplication::setSetuidAllowed(true) before creating the + QCoreApplication instance. + + - UTF-8 decoding: + * The QString and QTextCodec UTF-8 decoder changed behavior slightly: + when it encounters invalid sequences, it will insert one + replacement character per byte that is invalid, instead of one + replacement character for the whole invalid length. + +**************************************************************************** * Platform deprecation notice * **************************************************************************** @@ -24,17 +68,125 @@ information about a particular change. not tested, and most likely has issues that are not fully documented. **************************************************************************** -* Library * +* General * **************************************************************************** -QtWidgets ---------- + - Support for the following platforms has been removed, due to lack of + interest in updating support: INTEGRITY, VxWorks, Solaris on UltraSPARC + (with the Sun Studio compiler suite), AIX on POWER processors (with IBM + Visual Age compiler suite). + - Builtin command-line options such as -reverse, -session, -style + -etc. now all support double dash, e.g. --reverse, --session, + --style... + +**************************************************************************** +* Library * +**************************************************************************** QtCore ------ - Added QSignalBlocker, a RAII-style wrapper around QObject::blockSignals(). + - QLibraryInfo provides information on how Qt was built. + - Added class QMarginsF to support handling margins with floating-point + values. + + - Atomic support: + * Added more operations to the atomic classes, including operator T(), + operator=(T), operator++, operator--.
