Release note

Qt 6.2.3 release is a patch release made on the top of Qt 6.2.2.
As a patch release, Qt 6.2.3 does not add any new functionality but provides
bug fixes and other improvements and maintains both forward and backward
compatibility (source and binary) with Qt 6.2.2.

For detailed information about Qt 6.2, refer to the online documentation
included in this distribution. The documentation is also available online:


The Qt version 6.2 series is binary compatible with the 6.1.x series.
Applications compiled for 6.1 will continue to run with 6.2.

Some of the changes listed in this file include issue tracking numbers
corresponding to tasks in the Qt Bug Tracker:


Each of these identifiers can be entered in the bug tracker to obtain
more information about a particular change.

To make it easier to port to Qt 6, we have created a porting guide to
summarize those changes and provide guidance to handle them. In the
guide, you can find links to articles about changes that may affect your
application and help you transition from Qt 5.15 to Qt 6:


Important Changes


  • fa2197202a Do not include qloggingcategory.h in public headers
    The qguiapplication.h header no longer implicitly includes
    qloggingcategory.h. If your code depends on the transitive include,
    explicitly include where needed.

  • c13101b0b3 Fix deserializing Qt 5.x fonts through QDataStream
    Fixed a problem deserializing the family of fonts that had been
    serialized using QDataStream in Qt 5.

  • 5d344408cc QAnyStringView: fix broken implicit conversion from
    Implicit conversion from QStringBuilder to QAnyStringView now works as

  • 03274775ec QImageReader: check allocation limit for minimum 32 bpp
    When checking allocation limit during image reading, the memory
    requirements are now calculated for a minimum of 32 bits per pixel,
    since Qt will typically convert an image to that depth when it is used
    in GUI. This means that the effective allocation limit is significantly
    smaller when reading 1 bpp and 8 bpp images.

  • b55957b904 QObject: don't #include qproperty.h
    The qobject.h header no longer implicitly includes qproperty.h. If your
    code depends on the transitive include, explicitly include
    where needed.

  • ac9cc22c09 QVERIFY_EXCEPTION_THROWN: re-throw unknown exceptions
    Now re-throws unknown exceptions (= not derived from std::exception)
    (was: swallowed them and returned from the test function), in order to
    play nice with pthread cancellation.

  • 440a87248e QSharedPointer: fix counter-productive QT_PREPEND_NAMESPACE
    use in qHash() impl
    The qHash(QSharedPointer) overload can now use qHash(X) overloads
    found (only) through ADL (was: ADL was disabled due to qualified lookup
    of qHash(X

  • 150a897a83 Fix gaps between lines of selection
    Fixed an issue where there would sometimes be visible gaps in
    selections spanning multiple lines.

  • f622090b1d QNAM: Disable h2c by default
    Support for clear-text http/2 was disabled due to incompatibility with
    certain servers. If you were relying on this feature you must re-enable
    it by setting the QT_NETWORK_ALLOW_H2C environment variable. For a later
    version of Qt it will get a dedicated attribute.

  • 669b454378 Add _make_aab target
    Add the extra _make_aab targets for each executable target, that can be
    used to generate android app bundles. Also add aab metatarget to build
    all _make_aab targets that are created in the project.

  • ec613a4649 Fix overlapping text for Osaka font on macOS
    Fixed a problem where using the Osaka font would lead to overlapping

  • 9a9d960b12 QFuture: support cancellation of continuation chain through
    The chain of continuations attached to a future now can be cancelled
    through cancelling the future itself at any point of the execution of
    the chain, as it was documented. Previously canceling the future would
    cancel the chain only if it was done before the chain starts executing,
    otherwise the cancellation would be ignored. Now the part of the chain
    that wasn't started at the moment of cancellation will be canceled.

  • 46599ec418 Fix missing characters or assert with certain font sizes
    Fixed an issue where characters would in some rare cases be missing
    from text, depending on font metrics, font size and system scale factor.

  • 3bf23b7118 Don't change resolve mask when setting brush doesn't change
    Setting a brush on a palette that is identical to the current brush no
    longer sets the resolve mask bit for that particular role, so items
    using the palette will continue to inherit changes from parent items.

  • 82e965c35e QVarLengthArray: fix size update on failed append()
    Fixed a bug whereby a failed append() would leave the container with an
    inconsistent size().

  • 52c9543475 QVarLengthArray: fix UB (precondition violation) in range-
    Fixed a bug where range-erase() could invoke undefined behavior when
    called with an empty range.

  • c721dff3f3 Trust CoreText-provided vertical metrics on macOS
    Fixed an issue where certain fonts, such as Monaco, would have a
    different line spacing than expected.

  • b05c9898cc QList: fix typo in QList(It, It)
    Fixed a regression that caused the range constructor to fail for pure

  • 4e669763bd QVarLengthArray: widen append(p, n)'s contract
    The counted-range-append() function (append(ptr, n)) now accepts ptr ==
    nullptr, provided n == 0, too (was: triggered assertion).

  • f3842c09b7 QVariant: use a typedef name when saving user types to
    If QDataStream is used with a QDataStream::Version < Qt_6_0 to
    serialize a user type that was registered via a typedef with the
    metatype system, the typedef's name is used in the stream instead of the
    non-typedef name. This restores compatibility with Qt 5, allowing
    existing content to read the same QDataStreams; reading from older Qt 6
    versions should not be affected. (Note: if more than one typedef name is
    registered, it's indetermine which name gets used)

  • 0952ec8a5f QStringBuilder: fix quadratic behavior in op+=
    Fixed quadratic behavior when repeatedly appending string-builder
    expressions (using operator+=) to QString/QByteArray objects.

  • 7f3ca223a6 QTestData: fix streaming of u8 string literals in C++20
    Fixed streaming of u8 string literals in C++20 mode.

  • 60f3d7f324 QByteArray: avoid detach() in a no-op replace()
    A replace(pos, n, after) call no longer detach()es when n ==
    after.size() == 0.

  • 3d446c236a SQLite: Update SQLite to v3.37.0
    Updated SQLite to v3.37.0


  • 72402a9160 Fix missing glyphs when changing distance field parameters
    Fixed an issue where glyphs would sometimes be missing when changing
    the environment variables that define how distance fields are generated
    to certain values.

  • 9e6274e180 qquickdeliveryagent: Fix drag events being sent in the
    wrong order
    Now sends DragArea leave events before enter events when appropriate

  • db9adec4b1 Fix focus for items inside a QQuickWidget in a

  • 0798e34ce6 Make atlasing of compressed textures opt-in again
    Disable atlasing of compressed textures by default. Can be enabled with


  • 048f4317 Don't build XComposite buffer integration by default


  • d234a3c Fix loading of LottieAnimation::source

    relative URL.
