\title What's New in Qt 6.6
\brief Lists the new features in Qt 6.6.
\ingroup whatsnewqt6
\section1 New and Restored Modules in Qt 6.6
Qt 6.6 adds the following modules and tools:
\section2 New and Restored Modules in Technical Preview
\note API and ABI stability is not guaranteed.
\section2 Qt Graphs Module
Qt Graphs is meant to be the replacement module for Qt Data Visualization. It uses
Qt Quick 3D as the rendering engine to provide support for native graphics
backends, instead of relying on OpenGL 2.1, like Qt Data Visualization does.
The module will provide most, if not all of the functionality of Qt Data Visualization.
Some advanced features may be incomplete in Technical Preview.
\section1 New Features in Qt 6.6
\section2 Qt Core Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt GUI Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt Location Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt Network Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt PDF Module
\list
\li The new QPdfLinkModel class provides the link geometry and destinations
on a specified page.
\li QPdfDocument::pageModel() implements Qt::DecorationRole to render
page thumbnails on-demand.
\li The new QPdfPageSelector class is a specialized QSpinBox for
selecting a page in widget-based PDF viewers.
\endlist
\section2 Qt Positioning Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt QML Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt Quick Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt Quick Controls Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt Quick 3D Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt Serial Bus Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt Sql Module
\list
\li A plugin for \l {https://www.mimer.com/} {Mimer SQL} was added
\li MySQL/MariaDB gained the new connect options MYSQL_OPT_PROTOCOL,
MYSQL_SHARED_MEMORY_BASE_NAME, MYSQL_OPT_TLS_VERSION, MYSQL_OPT_SSL_MODE
\li The ODBC plugin now returns all native error codes in QSqlError
\li QSqlQuery got two new functions boundValueName()/boundValueNames()
\endlist
\section2 Qt Test Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt TextToSpeech Module
The QTextToSpeech class learned a few more tricks that are available with all
engines:
\list
\li Applications can add multiple chunks of text to a synthesizing engine
via \l{QTextToSpeech::}{sayNext}.
\li The new \l{QTextToSpeech::}{aboutToSynthesize} signal gets emitted just
before a chunk of text gets synthesized.
\endlist
Not all new features are available with every engine. Applications can use the
new \l{QTextToSpeech::}{Capabilities} flag and \l{QTextToSpeech::}{engineCapabilities}
property to check which of the following new features the currently used engine
supports:
\list
\li If the engine has the \l{QTextToSpeech::Capabilities}{Synthesize}
capability, QTextToSpeech can now synthesize text into PCM data. The
\l{QTextToSpeech::}{synthesize} function can be used with a callable that
receives chunks of PCM data as a QByteArray and QAudioFormat asynchronously,
or it can emit a signal carrying a chunk of data when it has been synthesized.
\li If the engine has the \l{QTextToSpeech::Capabilities}{WordByWordProgress}
capability, QTextToSpeech emits the \l{QTextToSpeech::}{sayingWord} signal
for each word in the current chunk of text as it gets spoken.
\endlist
\section2 Qt WebEngine Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt WebView Module
\list
\li Nothing to see here. //! TODO Clean this up before release.
\endlist
\section2 Qt Widgets Module

\li Nothing to see here. //! TODO Clean this up before release.
\endlist
