+****************************************************************************
+* Important Behavior Changes *
+****************************************************************************
+
+ - [QTBUG-63150] Characters invalid in XML, such as 0x0 or 0xfffe, as well
+ as strings containing unmatched UTF-16 surrogates are now suppressed
+ from the output of QXmlStreamWriter and cause the error flag to be set.
+
+ - Logging (including qDebug and qWarning):
+ * The QT_LOGGING_TO_CONSOLE environment variable has been deprecated.
+ Use the more specific QT_ASSUME_STDERR_HAS_CONSOLE or
+ QT_FORCE_STDERR_LOGGING, depending on your usecase.

+
+****************************************************************************
+* Library *
+****************************************************************************
+
+QtCore
+------
+
+ - [QTBUG-38156] Apple Unified Logging is now supported on Apple platforms.
+
+ - QAbstractItemModel:
+ * Added QAbstractItemModel::checkIndex(), a debugging function for
+ QAbstractItemModel subclasses.
+
+ - QBitArray:
+ * Added fromBits(), which creates a QBitArray from a dense bit array,
+ and bits(), which returns that.
+
+ - QDateTime:
+ * [QTBUG-64401] Years up to 9999 can now be parsed without error
+ (previously 8000 and beyond were treated as invalid) in all formats
+ (not only in ISO format). Widgets handling dates now support dates to
+ 9999, likewise.
+ * [QTBUG-63072] When parsing dates and times from strings, fixed-width
+ date-time fields, such as a "dd" for day, QDateTime now rejects all
+ values that should be padded, rather than only doing so when the value
+ is a prefix of some value that would fill the field-width. Use a
+ single letter for the field, e.g. "d" for day, if you want to accept
+ short values. (QDateTimeEdit is not affected.)
+
+ - QJsonValue:
+ * fromVariant() conversion now converts from QUrl and QUuid using
+ special encoding forms to ensure best JSON compatibility.
+
+ - QLockFile:
+ * [QTBUG-63425] QLockFile can now properly conclude that a lock file
+ from a previous boot of the same device is stale and can be removed.
+ This is implemented only for Linux and Apple operating systems.
+
+ - QMetaObject:
+ * [QTBUG-66744] It is now possible to use template class instances
+ inheriting from a Q_GADGET in Qml.
+
+ - QSaveFile:
+ * [QTBUG-66268] Fixed an issue that would cause QSaveFile::commit() to
+ fail if Unix signals were delivered at the same time.
+
+ - QScopedPointer:
+ * Added get(), for compatibility with std::shared_ptr.
+
+ - QSharedPointer:
+ * Added get(), for compatibility with std::shared_ptr.
+
+ - QString:
+ * Added remove() overload taking QLatin1String.
+
+ - QStringBuilder:
+ * Added support for char16_t characters and strings.
+ * Added support for QStringView.
+
+ - QSysInfo:
+ * [QTBUG-63425] Added machineUniqueId() and bootUniqueId().
+
+ - QThread:
+ * [QTBUG-53357] Changed how Qt thread priorities are mapped to QNX
+ system thread priorities.
+
+ - QUrl:
+ * Fixed a bug in parsing IPv6 addresses with more than 4 hex digits in a
+ component.
+
+ - QUuid:
+ * Added a parameter to both toString() and toByteArray() to allow
+ controlling the use or not of the braces and dashes in the string
+ form.
+
+ - QVarLengthArray:
+ * Added rvalue overloads of prepend and insert.
+ * QVarLengthArray can now contain movable but non-copyable types, such as
+ std::unique_ptr.
+ * Added missing rvalue overload of operator+=() and operator<<().
+
+ - QVariant:
+ * Conversions of QDateTime to strings now contain the millisecond
+ components.
+
+ - QVector:
+ * Added rvalue overloads of prepend and insert.
+ * Added missing rvalue overload of operator+=() and operator<<()
+
+QtGui
+-----
+
+ - [QTBUG-59762] The QT_QPA_PLATFORM environment variable and the -platform
+ argument now support a list of platform plugins in prioritized
+ order. Platforms are separated by semicolons.
+
+ - QGuiApplication:
+ * Added fontChanged() signal.
+
+ - QIcon:
+ * [QTBUG-33123] Added fallbackSearchPaths() that will be used to find
+ icons missing in the current icon theme.
+
+ - QStaticText:
+ * [QTBUG-65836] Fixed explicitly set width not being respected.
+
+ - Text:
+ * [QTBUG-45957] Fixed a bug where QStaticText would not use the
+ QPainter's pen color for text when other text colors were also in use.
+ Internally this reserves QColor(0, 0, 0, 0) for use with QStaticText.
+ * Added QFontMetrics::horizontalAdvance() and
+ QFontMetricsF::horizontalAdvance() to replace the confusingly named
+ width() function. The latter has now been deprecated.
+ * [QTBUG-65345] Fixed an issue where changing the letter spacing type of
+ a QTextCharFormat would not cause its font to update.
+
+QtNetwork
+---------
+
+ - QHostAddress:
+ * Added isGlobal(), isLinkLocal(), isSiteLocal(),
+ isUniqueLocalUnicast(), and isBroadcast() classification functions to
+ complement isLoopback() and isMulticast().

+ component.
+

+ * [QTBUG-61397] Added Http2DirectAttribute to enable 'direct' HTTP/2
+ protocol without ALPN/NPN and without protocol upgrade negotiations.
+ * [QTBUG-66913] Fixed a crash in HTTP/2 protocol handler (when server
+ responds with redirect or some error status code early, not wating
+ for a stream to be closed on client side).
+
+ - QNetworkInterface:
+ * Added type().
+ * Added maximumTransmissionUnit().
+ * Added preferredLifetime() and validityLifetime() to
+ QNetworkAddressEntry that report the remaining lifetime of the address
+ in the network interface.
+ * Added dnsEligibility() to QNetworkAddressEntry to indicate whether the
+ address is eligible or not for publication in DNS or similar
+ mechanisms.
+ * [QTBUG-67226] Fixed a regression in reporting the local address of a
+ point-to-point tunnel network interface.
+
+ - QSslSocket:
+ * [QTBUG-67584] When using OpenSSL 1.1, it now correctly sets protocol
+ version for QSsl::TlsV1_0, QSsl::TlsV1_1 and QSsl::TlsV1_2.
+ * [QTBUG-67112] On WinRT QSsl::SecureProtocols (default) now enables
+ TLSv1.1 and TLSv1.2.
+ * On WinRT QSsl::TlsV1SslV3 now enables SSLv3 and not just TLSv1.
+
+QtPrintSupport
+--------------
+
+ - Larger improvements to the CUPS print dialog.
+ * Added an advanced options tab in the printer properties, containing
+ all the printer options exposed through the CUPS API.
+ * Implemented support for installable options (add-ons to the printer).
+ * Added support for storing the selected settings between application runs.
+ * Added support for localized options in the advanced tab.
+ * The CUPS print dialog now supports printing of arbitrary ranges.
+
+ - QPrintDialog

+ - PostgreSQL support:
+ * [QTBUG-63714] Added support for forward-only queries (requires libpq
+ version 9.2 or later).
+ * Added support for multiple result sets.
+
+ - QSqlDatabase:
+ * [QTBUG-216] QSqlDatabase::database() will return an invalid
+ QSqlDatabase if the calling thread does not own the requested
+ QSqlDatabase.
+
+QtTest
+------
+
+ - The qtest_global.h header is now deprecated. Include qttestglobal.h
+ instead.
+ - Added QAbstractItemModelTester, a class to help testing item models.
+
+QtWidgets
+---------
+
+ - [QTBUG-62094] QDesktopWidget has been deprecated. Use the corresponding
+ QScreen functions instead.
+ - [QTBUG-49374][QTBUG-65237][QTBUG-49374] Fixed several issues related
+ to HiDPI support in QStyle.
+
+ - Item views:
+ * [QTBUG-48725] QTreeView now calls canFetchMore() and fetchMore() when
+ the bottom of the QTreeView is scrolled to.
+ * [QTBUG-65082] Add ability to show QJsonValue::Bool/Double to
+ QTreeView, QTableView and QListView.
+
+ - QAbstractItemModel:
+ * Implemented improved support for the optional "role" parameter in the
+ "dataChanged" signal.
+
+ - QColorDialog:
+ * [QTBUG-64500] Fixed persistence of custom colors when relaunching an
+ application.
+
+ - QHeaderView:
+ * Flat treeviews can now allow the user to move the first column (like
+ in Qt 4.x) using the new method QHeaderView::setFirstSectionMovable().
+ * MinimumSectionSize/MaximumSectionSize is now respected when calling
+ resizeSection().
+
+ - QLineEdit:
+ * Implemented quick text selection by mouse in QLineEdit.
+ * Placeholder text is now used as accessible description if the latter
+ has not been set.
+
+ - QListView:
+ * QListView now honors css :first/:middle/:last Pseudo-States.
+
+ - QMenu:
+ * [QTBUG-25669] Fixed a bug in QMenu that caused QMenuBar::triggered() to
+ be fired multiple times.
+
+ - QMenuBar:
+ * Added overloads of addAction() using Qt 5 signals and slots.
+
+ - QStandardItemModel:
+ * [QTBUG-45114][QTBUG-10872] Fixed setItemData() incorrectly deleting
+ unmodified data. That behavior is not following QAbstractItemModel's
+ documented behavior which is no modification of data not provided in
+ parameter.
+
+ - QStyle:
+ * [QTBUG-53094] Added SH_ComboBox_AllowWheelScrolling as a style hint to
+ enable/disable the use of the mouse wheel in a QComboBox. This
+ defaults to true in all styles except the macOS one so there is no
+ change in existing behavior.
+
+ - QTextEdit/QPlainTextEdit
+ * [QTBUG-63868] context menus will now open on right mouse click even if
+ the focus policy is Qt::NoFcous (allowing text copy).
+
+ - QTreeWidgetItem:
+ * QTreeWidgetItem::insertChildren now ignores insertions happening at
+ invalid indices, for consistency with QTreeWidgetItem::insertChild.
+
+****************************************************************************
+* Platform-specific Changes *
+****************************************************************************
+
+Android
+-------
+
+ - The application and dependent Qt libraries are now loaded on the same
+ thread as main() is run on, ensuring that global static initializers,
+ constructor functions, and main() are all run on the same thread. The
+ same applies during application shutdown, for destructors of global
+ objects, and destructor functions.
+
+Linux/EGLFS
+-----------
+
+ - [QTBUG-63088] The DRM+GBM backend now exposes the DRM/GBM device handle
+ under the key "dri_fd", queriable via nativeResourceForIntegration().
+
+Linux/XCB
+---------
+
+ - [QTBUG-56452] Added missing dead key symbols, enabling their use with
+ the "compose" input module.
+ - Added support for flatpak portals. Flatpak is a software utility for
+ software deployment and package management. It provides a sandbox
+ environment in which users can run applications in isolation from the
+ rest of the system. To communicate with the system flatpak uses portals,
+ which are designed to be a bridge between sandboxed applications and
+ desktop/system running on user's computer. Flatpak runs automatically
+ this as service, called xdg-desktop-portal, which exports portals on DBus
+ and which are by default visible to all applications running under
+ Flatpak.
+ - [QTBUG-44938] Qt now falls back to X11 core keycode information if an XKB
+ keymap could not be determined through the connection.
+
+ - ibus:
+ * Support ForwardKeyEvent signal
+
+Windows
+-------
+
+ - [QTPM-487][QTBUG-53024][QTBUG-43190][QTBUG-61926][QTBUG-38499]
+ [QTBUG-38337][QTBUG-38501][QTBUG-38502][QTBUG-38504][QTBUG-38505]
+ [QTBUG-38507] The Windows Accessibility back end, formerly based on
+ Microsoft Active Accessibility, was replaced with a new implementation
+ based on Microsoft UI Automation.
+
+ - [QTBUG-44594] Added support for End-User Defined Characters in Qt.
+
+iOS
+---
+
+ - [QTBUG-59042] The Apple Pencil now generates QTabletEvents, with the
+ complete feature set (tilt, rotation, pressure).
+
+macOS
+-----
+
+ - QMacStyle does no longer depend on HITheme — or Carbon for that matter.
+ Its implementation now relies exclusively on AppKit and custom code for
+ rendering and pixel metrics.
+
