    \section1 New Modules in Qt 6.11

    Qt 6.11 adds the following modules:

    \list
      \li \l {Qt Canvas Painter} - Accelerated 2D painting solution for Qt Quick
          and QRhi-based render targets.
      \li \l {Qt OpenAPI} - An extension of the upstream Open API generator that
          generates Qt HTTP clients, typically used for RESTful APIs.
      \li \l {Qt TaskTree} - Provides a declarative way to compose and execute
          asynchronous task workflows.
      \li Qt Labs StyleKit - A dedicated styling API that streamlines styling
          Qt Quick Controls through a set of shared design attributes.
    \endlist

    The new modules are in \e{Technical Preview}, excluding their API from
    \l{Compatibility promises}{Qt's compatibility promises}.

    \section1 New Features in Qt 6.11

    \section2 ActiveQt Module

    No noteworthy changes.

    \section2 Qt Bluetooth Module

    No noteworthy changes.

    \section2 Qt CoAP Module
    \list
      \li \l QCoapClient::bindInterface allows to bind the communication to a specific
          network interface.
    \endlist

    \section2 Qt Core Module
    \list
      \li \l QDate is now weakly incrementable, i.e. implements pre- and post-fix increment
          (and decrement) operators, and can be used in a C++20 \c{std::views::iota}.
      \li \l QJniObject APIs can now be called with \c{std::expected} (or an equivalent type)
          as the return type, in which case Java exceptions are not consumed by the framework
          and instead passed back to the caller as the unexpected result.
      \li \l QRangeModel::ItemAccess provides a customization point for accessing role data
          of a multi-role item type.
      \li \l QRangeModel can now be used with C++ ranges that don't provide a constant
          \c{std::begin/end} implementation, such as C++20 \c{std::views::filter}.
      \li With ranges that use the same QObject subclass for multi-role items, the new
          \l QRangeModel::autoConnectPolicy can be set to Full or OnRead to connect the
          changed-signals of all exposed properties of QObject items to the corresponding
          \l {QAbstractItemModel::}{dataChanged()} signal emission.
      \li \l QRangeModelAdapter provides a typical C++ container API to the range a QRangeModel
          operates on, ensuring that relevant QAbstractItemModel signals are emitted on
          changes, without user code having to work with QModelIndex. This new class is under
          technology preview.
    \endlist

    \section2 Qt D-Bus Module

    No noteworthy changes.

    \section2 Qt Graphs Module

      \li Added \l{QPieSlice::subSlicesCount}{subSlicesCount},
          \l{QPieSlice::subSlicesSum}{subSlicesSum},
          \l{QPieSlice::subSlicesRatio}{subSlicesRatio}, and
          \l{QPieSlice::sliceChildren}{sliceChildren} properties in \l{QPieSlice} to allow
          creating sub slices in pie and donut graphs
      \li Added \l{QDateTimeAxis::visualMin}{visualMin} and
          \l{QDateTimeAxis::visualMax}{visualMax} properties in \l{QDateTimeAxis} and
          \l{QValueAxis} to hold the visible axis ranges
      \li Added \l{QAreaSeries::gradient}{gradient} and
          \l{QAreaSeries::selectedGradient}{selectedGradient} properties in \l{QAreaSeries}
          to allow using gradients in area graphs

          margins
      \li Added support for multiple \l{QBarSeries} in one \l[QML]{GraphsView}.
      \li Added support for negative values in \l{QBarSeries}.
      \li Added support for invalid values in \l{LineSeries} which results in visual gaps.
    \endlist

    \section2 Qt GRPC Module

    \list
        \li Added the new Client Interception mechanism to QtGrpc to enable
            interception and modification of outgoing requests and incoming responses.
        \li Qt 6.11 adds comparison operators (\c{operator==} and \c{operator!=}) for
            \l QGrpcCallOptions and \l QGrpcChannelOptions, enabling direct equality
            checks between option objects.
        \li \l QGrpcOperation class introduces a
            \l{QGrpcOperation::}{serverInitialMetadataReceived()} signal that notifies
            RPC handlers as soon as the server initial metadata is received.
        \li \l QGrpcChannelOptions class now provides
            \l{QGrpcChannelOptions::}{filterServerMetadata()} and
            \l{QGrpcChannelOptions::}{setFilterServerMetadata()} methods to control
            whether protocol-related metadata is included in server responses.
        \li The \l QtGrpc namespace introduces the \l{QtGrpc::}{RpcType} enum and
            \l{QtGrpc::}{RpcDescriptor} struct to describe gRPC methods with their
            service name, method name, and communication pattern.
    \endlist

    \section2 Qt GUI Module
    \list
        \li Accessibility events of the new QAccessible::RoleChange type get emitted by the
            docking window framework when dock widgets change between docked and floating.
        \li The new accessibility role \l{QAccessible::Role}{Switch} is used by the Switch
            type in Qt Quick Controls.
        \li The new accessible attribute \l {QAccessible::Attribute}{Orientation} is used by
            sliders and similar controls to report their orientation to accessibility clients.
        \li QRawFont got an API to get the \l {QRawFont::}{glyphCount()} and to look up the
            \l {QRawFont::}{glyphName()} for a glyph index of the font.
        \li QTextCharFormat got new APIs to set \l {QTextCharFormat::setFontFeatures()}
            {font features} and \l {QTextCharFormat::setFontVariableAxes()}{variable axes}.
    \endlist

    \section2 Qt HttpServer Module
    \list
        \li Added support for HTTP/1.0 clients.
        \li Qt 6.11 introduces configurable request size limits to \l QHttpServerConfiguration,
            allowing applications to protect against oversized requests. New methods include
            \l {QHttpServerConfiguration::}{setMaximumUrlSize()},
            \l {QHttpServerConfiguration::}{setMaximumTotalHeaderSize()},
            \l {QHttpServerConfiguration::}{setMaximumHeaderFieldSize()},
            \l {QHttpServerConfiguration::}{setMaximumHeaderFieldCount()},
            and \l {QHttpServerConfiguration::}{setMaximumBodySize()}. When limits
            are exceeded, the server responds with appropriate HTTP error codes (414, 431,
            or 413).
        \li Route handlers can now return \c QFuture<void> and respond using a
            \l {QHttpServerResponder}&& argument in another thread, enabling CPU-intensive
            request processing to be offloaded from the main server thread. For HTTP/2
            connections, multiple requests can be processed concurrently, while HTTP/1.x
            connections process requests sequentially but still benefit from background
            processing. Socket I/O always remains in the QHttpServer thread.
        \li \l {QHttpServerResponder::}{isResponseCanceled()} was added to
            \l QHttpServerResponder, allowing handlers to detect when a client
            has disconnected and exit early to avoid unnecessary processing.
    \endlist

      \li \l{VectorImage}: Added support for animating shapes along paths.
      \li \l{VectorImage}: Added support for morphing animations (interpolating between two shapes.)
      \li \l{VectorImage}: Added support for matte layers.
    \endlist

    \section2 Qt Multimedia Module
    \list
      \li Added callback-based overloads for the start methods of \l{QAudioSource} and \l{QAudioSink} to
          allow real-time audio processing.
    \endlist

    \section2 Qt Network Module
    \list
      \li \l QNetworkRequest can now specify the TCP Keep Alive parameters for the current
          request. Also, the default TCP Keep Alive parameters have been changed in
          \l QNetworkAccessManager and now the inactive connections are terminated after two
          minutes of inactivity.
    \endlist

    \section2 Qt Network Authorization Module

            order were established to improve screen reader support and keyboard navigation.
    \endlist

    \section2 Qt Protobuf Module
    \list
        \li The \l qprotobufmessage_cast() function provides safe downcasting of
            \l QProtobufMessage pointers. Similar to \l qobject_cast() or \c dynamic_cast(),
            it enables easy and safe run-time type checking and conversion.
    \endlist

    \section2 Qt Qml Module
    \list
        \li Added workspace support in QML Language Server.
        \li Added go to C++ definition support in QML Language Server.
        \li Added support to silence context property warnings via a \c{.contextProperties.ini} configuration file for qmllint.
        \li Introduced \c{override} and \c{virtual} keywords which, together with the existing \c{final} keyword and tooling support,
            help prevent accidental property shadowing and allow explicit property overriding in QML.
            See \l{qtqml-syntax-overridesemantics.html}{Property Shadowing and Override Semantics} for details.
        \li Gave the \l easingCurve value type a name and transformed the
            \l Easing namespace into a singleton.
        \li Added APIs to QQmlContext to get the \l{QQmlContext::childContexts()}
            {list of child contexts} and to \l{QQmlContext::findObjectRecursively()}{find an object
            by id}.
        \li Added GroupAttributesTogether option to qmlformat. This implies the NormalizeOrder option
            and reorders QML categories without sorting attributes (property definitions, property bindings,
            methods, signals, and enums).
        \li Added SingleLineEmptyObjects option to qmlformat.
            This prevents empty objects from expanding into a second line.
    \endlist

    \section2 Qt Quick Module
    \list
      \li Added CMAKE command \l{qt_target_qml_from_svg} for converting from SVG to QML at build
          time.
      \li Added APIs to \l Flickable to \l{Flickable::positionViewAtChild}{position} or \l{Flickable::flickToChild}{flick}
          the view to a child and to \l{Flickable::flickTo}{flick to a position}.
    \endlist

    \section2 Qt Quick Controls Module
    \list
    \li Added \l DoubleSpinBox, which is similar to \l SpinBox but supports
        floating-point values.
    \li Added \l {DialogButtonBox::}{defaultButton} and
        \l {DialogButtonBox::}{defaultStandardButton} to \l DialogButtonBox.
        When set, the respective button will be highlighted and receive
        activeFocus whenever the DialogButtonBox gets focus.
    \endlist

    \section2 Qt Quick Dialogs Module

    No noteworthy changes.

    \section2 Qt Quick Effects Module
    \list
        \li Qt 6.11 adds four new properties to \l{RectangularShadow}
            for independent corner radius control: \l{RectangularShadow::}{topLeftRadius},
            \l{RectangularShadow::}{topRightRadius},
            \l{RectangularShadow::}{bottomLeftRadius}, and
            \l{RectangularShadow::}{bottomRightRadius}. Each property
            falls back to the existing \l{RectangularShadow::}{radius} property
            if not set, or creates a sharp corner when set to zero, enabling more
            flexible shadow shapes with different corner radii per corner.
    \endlist

    \section2 Qt Quick Layouts Module

    No noteworthy changes.

    \section2 Qt Quick Test Module

        Up, Down) and the Return can be used for navigating between keyboard keys when the input
        panel is visible. The property default is based on the build-time configuration flag
        \c QT_VIRTUALKEYBOARD_ARROW_KEY_NAVIGATION.
    \li Added \l{KeyboardStyle::}{keyboardDesignMaximumHeight} property
        to \l KeyboardStyle type. Use this to prevent the keyboard overlapping most of the screen.
    \endlist

    \section2 Qt WebEngine Module
    \list
    \li Qt WebEngine is now based on Chromium 140.
    \li Chromium has added new Rust components which are intended to replace their C++ counterparts.
        Qt WebEngine can now be optionally built using these Rust components. This requires
        installing a Rust toolchain and configuring with \c{-feature-webengine-rust-build}.
        The default behavior is to build with the older C++ components.
    \li Added \l{QWebEngineProfile::PersistentCookiesPolicy::}{OnlyPersistentCookies}

    \endlist

    \section2 Qt WebView Module
    \list
        \li Added C++ bindings for WebView, allowing you to use the module in
            Qt Widgets-based applications. The new C++ APIs are released in
            Technology Preview status, and may be changed in the future.
    \endlist

    \section2 Qt Widgets Module
    \list
        \li QWizard got a new \l{QWizard::StretchBanner}{StretchBanner}
            option to stretch the banner across the entire width of
            the wizard.
        \li QAbstractItemView got a new \l{QAbstractItemView::}{keyboardSearchFlags}
            property that allows tuning how the default implementation of
            keyboardSearch() matches the given string against the model's data.
        \li QColumnView got a new \l{QColumnView::}{previewColumnVisible} property
            that specifies whether the preview column is visible.
        \li The new QStyleOptionMenuItemV2 class adds a flag that indicates whether
            the mouse is pressed on the item getting rendered by the style.
        \li QTabBar now emits \l{QTabBar::}{tabCloseRequested} when a tab is middle clicked
            if \l{QTabBar::}{tabsClosable} is true.

    \list
    \li Added comprehensive support for QML singleton types, including a new
        \c{\qmlsingletontype} command, automatic detection of the
        \c{QML_SINGLETON} macro, and recognition of \c{pragma singleton} in
        QML files.
    \li QDoc now has full support for QML module aliases (\c{import ... as ...}
        syntax), including linking, syntax highlighting for qualified
        identifiers, and correct markup for property notation such as
        \c{anchors.fill} and attached properties such as
        \c{Component.onCompleted}.
    \li You can use the new \c{\toc}/\c{\endtoc} and \c{\tocentry} command for
        specifying hierarchical table of contents structures in documentation
        source files. QDoc generates \c{<project>_toc.xml} files for navigation
        sidebars.
    \li The \l {overload-command}{\\overload} command now takes an optional
        argument. Use the \c{\overload primary} syntax to designate the primary
        function in an overload set.
    \li QDoc now generates contextual connection examples for overloaded signals
        and slots.
    \li The \c{includeprivate} configuration variable enables documentation of
        private C++ members. Pure virtual functions are now unconditionally
        documented.
    \li \b{C++20 Concepts}: QDoc now extracts and displays C++20 requires
        clauses for function and class templates. Both template-head and
        trailing constraint positions are supported.
    \li The \l {code-command}{\\code} command now accepts an optional argument
        to specify the programming language for the code block. Use "text" to
        disable syntax highlighting.
    \li The \c{\meta keywords} argument adds custom keywords as HTML \c{<meta>}
        elements for search engine optimization and post-processing.
    \li Explicit linking to QML attached properties is now supported using the
        "attached" link criterion, allowing disambiguation when regular and
        attached property names conflict.
    \li Template declarations with more than two parameters are now rendered in
        a multi-line format for improved readability. The HTML output uses the
        \c{template-block} CSS class for custom styling.
    \li QDoc now warns about undocumented C++ properties declared with
        \c{Q_PROPERTY}, ensuring consistent documentation coverage across all
        API elements.
    \li QDoc now warns about self-linking in \c{\sa} commands where a document
        links to itself.
    \li The \c{logwarnings} configuration variable makes QDoc write all warnings
        to a \c{<project>-qdoc-warnings.log} file. The new
        \c{logwarnings.disablecliargs} sub-option omits CLI arguments from the
        log header for portable logs.
    \li QDoc warnings now include the project name prefix for multi-module
        builds.
    \li \b{Configuration Improvements}:
        \list
        \li \c{imagesoutputdir}: Custom output subdirectory for images to
            solve file name clashes in multi-module builds.
        \li \c{internalfilepatterns}: Automatically marks classes as internal
            based on file/path name patterns, such as \c{*_p.h}.
        \li \c{projectroot}: Sets the root directory for converting absolute
            paths to relative paths in warning logs, improving portability
            across build environments. Also available as the
            \c{QDOC_PROJECT_ROOT} environment variable.
        \endlist
    \li Formatting commands now work in \c{\title} arguments, \c{\generatelist}
        works correctly in Qt help project TOC structures, and custom enumerator
        prefixes are supported in \c{\qmlenum}.
    \li The HTML structure for QML and C++ member documentation is unified. This
        change introduces new CSS classes (\c{qml-member}, \c{qml-property},
        \c{qml-method}, \c{qml-property-group}) in QDoc's HTML output.
    \li \b{Code Parsing}: Improved scoped enum resolution, QML inheritance
        handling with cycle detection, and correct preservation of declared
        types and variable information in index files.
    \li Added LLVM/Clang 21 compatibility, with minimum supported version
        updated to 17.0.6.
    \li The \c{\tableofcontents} command is officially deprecated.
    \endlist

    \section2 Qt Linguist
    \list
    \li Added \e{labels} as a way to categorize ID-based translations into
        meaningful groups without affecting the runtime behavior. See the
        \l{Text ID based translations} documentation and the
        \l{https://www.qt.io/blog/organizing-id-based-translations-with-labels-in-qt-linguist}
        {blog post} for more details.
    \li Added new i18n examples to the documentation.
    \li Added AI translation for Qt Linguist for automatic translations using
        LLMs. See the \l{AI translation} documentation and the
        \l{https://www.qt.io/blog/ai-powered-translation-comes-to-qt-linguist}
        {blog post} for more details.
    \li Added ltext2id executable for migrating projects from text-based
        translation to ID-based translation. See \l{Using ltext2id} for more
        details
    \li Added lcheck executable for performing batch validation on TS files.
        See \l{Using lcheck} for more details.
    \li Added support for C++ attributes in lupdate parser
    \li Deprecated use of //= metastrings in lupdate parser.
    \li Deprecated \c {lupdate -pro} option for processing .pro files directly.
        Use \c {lupdate-pro} instead.
    \li Removed lprodump executable. Its functionality is now available via
        the \c {lupdate-pro -dump-json} option.
    \endlist

    \section1 Platform Changes

    \section2 Build System Changes

    \list
    \li Added a -generate-vcpkg-manifest configure option. This generates a
        vcpkg.json file in the build directory. To just generate the
        manifest without configuring Qt, run configure with
        -generate-vcpkg-manifest -dry-run.
    \li When configuring with -vcpkg, generate a vcpkg manifest file in the
        build directory, and set VCPKG_MANIFEST_DIR to the build directory to
        use that manifest file. You can turn off the manifest generation with
        -no-generate-vcpkg-manifest. You can turn off setting the manifest
        directory by passing -- -UVCPKG_MANIFEST_DIR to configure.
    \endlist

    \section3 Windows
    \list
    \li Added support and detection of Windows 11 25H2 (Build 10.0.26200) via
        \l{QOperatingSystemVersion::Windows11_25H2}{QOperatingSystemVersion}.
    \li There are various accessibility improvements to top-level windows and focus.
    \li Improved refresh rate update handling.
    \li Added experimental support for \l{https://learn.microsoft.com/windows/arm/arm64ec}{ARM64EC}
        when using Visual Studio 2026. To use this configuration add \c{/arm64EC} to \c{CFLAGS} as
        well as \c{/arm64EC} and \c{/d2arm64ECMarkAllFuncsPatchable} to your \c{CXXFLAGS}
        environment variables on your Windows on ARM machine and configure and build Qt as you
        normally do.
