\title What's New in Qt 6.0
\brief Lists the new features in Qt 6.0.

\section1 Build System Changes in Qt 6
Building Qt from sources now requires CMake and Ninja. See
\l{Build System Changes in Qt 6} for more details on this and other
changes in configure.
\section1 Changes to Supported Modules
Qt 6.0 is streamlined compared to Qt 5 and some modules are no longer in the
default installation of Qt 6.0. Because of the modularized structure of Qt,
new modules or previous Qt 5 modules may appear in future releases of Qt 6.
For more information, visit the \l{All Modules} page.
The \l{Changes to Qt Modules in Qt 6} has a list of API changes.
\section1 New Modules in Qt 6.0
The following are new modules in Qt 6.0.
\list
\li \l{Qt 5 Core Compatibility APIs}
\li \l{Qt 5 Compatibility APIs: Graphical Effects}
\li \l[QtShaderTools]{Qt Shader Tools} - for graphics and compute
shaders
\endlist
\section1 Removed Modules in Qt 6.0
The following are Qt 5 modules that are not in Qt 6.0. They may be
re-introduced in a future release of Qt 6.

\section1 New Features in Qt 6.0
\section2 Qt QML Module
\list
\li QML Language
\list
\li Added JavaScript URL object support, providing native URL handling
in QML JavaScript code.
\li Allowed imports without version. If you omit the version from a QML
import statement the latest version of the module is imported.
\endlist
\li Module System
\list
\li Added \c import directive in qmldir files. This enables optional
imports and declarative module imports, allowing modules to declare
their dependencies explicitly.
\li Added qmlRegisterModuleImport() for procedurally adding imports to
a module. Don't do this unless you know what you're doing.
\li Added support for specifying resource (\c{:/some/path}) paths in
the QML2_IMPORT_PATH environment variable.
\li QML plugins can be optional now. The \c{optional} directive in
qmldir files specifies that the plugin doesn't have to be loaded if
the module's types are already present in the binary. This is
commonly the case for modules like QtQuick or QtQml.
\li Introduced support for purely-redirecting QML modules that only
import and re-export other modules without providing their own
types.
\endlist
\li Type System
\list
\li Introduced override behaviors
QML_LIST_PROPERTY_ASSIGN_BEHAVIOR_{APPEND|REPLACE|REPLACE_IF_NOT_DEFAULT}
for QQmlListProperty, giving more control over QML operations on
C++-declared list properties.
\li Added support for user-defined sequence types. Custom list types
can now be registered and used directly in QML using
QML_SEQUENTIAL_CONTAINER, enabling type-safe list properties
without needing to wrap elements in JavaScript objects.
\li Introduced two-component revision format (Major, Minor) for QML type
versioning, providing more granular control over API evolution.
\li Allowed singletons to be extended via QML_EXTENDED.
\li Allowed namespaces as extensions to types via QML_EXTENDED_NAMESPACE.
\li Allowed QML types from foreign namespaces via QML_FOREIGN_NAMESPACE.
