+Qt 5.15.2 is a bug-fix release. It maintains both forward and backward
+compatibility (source and binary) with Qt 5.15.1.

+distribution. The documentation is also available online:
+
+ https://doc.qt.io/qt-5.15/index.html
+
+The Qt version 5.15 series is binary compatible with the 5.14.x series.
+Applications compiled for 5.14 will continue to run with 5.15.
+
+Some of the changes listed in this file include issue tracking numbers
+corresponding to tasks in the Qt Bug Tracker:

+****************************************************************************
+* Library *
+****************************************************************************
+
+QtCore
+------
+
+ - QJsonObject:
+ * [QTBUG-86873] Fixed sorting in QJsonObject when parsing UTF-8 JSON text
+ so that searching works afterwards.
+
+ - QLocale:
+ * [QTBUG-74287] Fixed locale look-up when language is unspecified.
+ * [QTBUG-84669] Fixed QLocale::findLocaleDataById().
+ * [QTBUG-86306] Fixed incorrect guessing of the UTC time zone when the
+ system timezone name is unrecognized.
+
+ - QMimeDatabase:
+ * [QTBUG-85436] Fixed handling of glob-deleteall in QMimeDatabase.
+
+ - QStringView:
+ * [QTBUG-86516] A couple of methods have been added to QStringView that make
+ it easier to write code that is portable between Qt 5.15 and Qt 6. Those
+ include QStringView::split(), QStringView::count(), number conversion
+ methods (QStringView::toInt() and friends). A couple of overloads taking
+ QStringView have been added to QRegularExpression (match() and
+ globalMatch()) and QString (append(), prepend(), insert() and
+ localeAwareCompare()).
+
+ - QThreadPool:
+ * [QTBUG-87092] Fixed a race condition in QThreadPool::clear().
+
+ - QUrl:
+ * [QTBUG-86277] Changed QUrl::fromLocalFile() to accept Windows UNC paths
+ whose hostname component is not a valid Internet hostname. This makes QUrl
+ able to accept extended-length paths (\\?\), device namespace (\\.\),
+ WSL (\\wsl$), etc.
+
+ - QVector:
+ * [QTBUG-86392] Fixed a BC break in QVector's QArrayDataPointerRef constructor.
+
+ - Network:
+ * [QTBUG-85901] QNetworkRequest FollowRedirectsAttribute is now deprecated.
+ * [QTBUG-85902] Fixed a crash in HTTP/2 when handling Remote Disconnected.
+ * [QTBUG-85123] QAuthenticator now tries to get credentials before using GSSAPI.
+ * [QTBUG-85902] If QNAM asks for HTTP/2 or 1.1 and the server doesn't list either,
+ we now try to connect using HTTP/1(.1) just in case, to keep compatibility.
+ * [QTBUG-86418] Huffman compression now handles QByteArray's elements as
+ unsigned char to avoid an HTTP/2 crash when using unicode in an http header.
+
+QtGui
+-----
+
+ - Image formats:
+ * [QTBUG-87320] Fixed a crash in QImage conversions still ongoing on shutdown.
+ * [QTBUG-86702] Fixed a gif read error.
+ * [QTBUG-86691] Fixed an XPM read error caused by off-by-one in overflow check.
+ * [QTBUG-85193] SVG now allows smooth curve stroking of very wide lines.
+
+ - Input:
+ * [QTBUG-86207] We now ignore mouse events where globalPos contains NaN
+ to avoid a crash.
+ * [QTBUG-86253] Fixed a touch->mouse synthesis bug that caused widgets
+ to get stuck in pressed state.
+
+ - QPainter:
+ * [oss-fuzz-24615] Fixed a heap-buffer-overflow.
+ * [QTBUG-84267] Fixed a crash in QIcc::fromIccProfile.
+
+ - QScreen:
+ * [QTBUG-76902] QScreen now emits geometryChanged() when the logical DPI changes
+ so as to resize widgets and fonts after moving to a screen with different DPI.
+
+ - Text and fonts:
+ * [QTBUG-85016] Fixed a potential crash when rendering text with an empty font
+ database.
+ * [QTBUG-87267] We now fall back to using the family when doing an exact match
+ so that QFont::exactMatch() returns true for installed fonts.
+ * [QTBUG-85560] Fixed rendering unicode characters using a fallback font.
+ * [oss-fuzz-24702] QTextDocument's HTML parser now avoids an integer overflow that
+ resulted in extreme values for font pixelsize.
+
+QWidgets
+--------
+
+ - QCalendarWidget:
+ * [QTBUG-86307] The calendar widget now shows the year correctly after editing.
+
+ - QComboBox:
+ * [QTBUG-86580] QComboBox::currentText() now returns an empty string rather than
+ placeholderText if the text is empty.
+
+ - QGraphicsScene:
+ * [QTBUG-87174] Fixed a bug in the initialization of BSP trees to increase
+ the performance of QGraphicsScenes with non quadratic scene rectangles.
+
+ - QMenu:
+ * [QTBUG-77833] We now close popups on windowWillMiniaturize notification
+ so that context menus are not left visible when a window is minimized.
+
+ - QSpinBox:
+ * [QTBUG-86483] QSpinBox now avoids emitting valueChanged twice if the
+ application's handler takes longer than the press'n'hold timer.
+
+ - Dialogs:
+ * [QTBUG-87483] QFontDialog::selectedFont() is now correct at the time
+ the accepted signal is emitted.
+ * [QTBUG-10561] Fixed a reentrancy problem with processEvents() in
+ QProgressDialog::setValue() when using Qt::WindowModal with setValue()
+ connected to a signal in another thread using Qt::QueuedConnection.
+
+ - Item views:
+ * [QTBUG-86268] Fixed QTable/TreeView sortByColumn() when it's already sorted.
+ * [QTBUG-86166] Clipboard copy is now possible with more data types that can
+ be converted to strings.
+ * [QTBUG-85366] QTreeView now fetches as many nested entries from the model
+ as can fit into the view by by repeatedly calling canFetchMore() and
+ fetchMore() if necessary.
+ * [QTBUG-87057] Item views no longer allow CopyAction for InternalMove views,
+ and no longer lose items during drag-and-drop if a model only allows
+ MoveAction and doesn't override moveRows().
+ * [QTBUG-83313] Fixed CaseSensitivity handling for QRegularExpression in
+ QSortFilterProxyModel.
+
+ - Styles:
+ * [QTBUG-86411] Fixed a bug in Fusion that was adding unnecessary padding to
+ a groupbox without a title or indicator.
+ * [QTBUG-86587] Fixed QPushButton hit testing when a QStyleSheetStyle adds padding.
+
+QtSQL
+-----
+
+ - sqlite:
+ * Upgraded to v3.33.0
+
+ - PostgreSQL:
+ * [QTBUG-84356] QSqlDriver::subscribeToNotification() is no longer lost
+ if the PostgreSQL server restarts.
+
+ - Interbase:
+ * [QTBUG-83409] We now correctly read/write arrays to Interbase.
+ * [QTBUG-83152] Interbase now handles EXECUTE BLOCK statements correctly.
+
+QtXML
+-----
+
+ - [QTBUG-86547] Fixed a double deletion in QDomAttr::setNodeValue().
+
+Third-Party Code
+----------------
+
+ - Fixed copyright information for "XCB-XInput".
+
+ - Changed license text of "PCRE2 - Stack-less Just-In-Time Compiler"
+ component. The documentation (incorrectly) included the generic PCRE2
+ license so far.
+
+ - Fix aggregated copyright information of TinyCBOR component to reflect the
+ years in the individual source files. Note that this is not same as the
+ Copyright year in the upstream MIT license text.
+
+ - Changed classification of the wintab license from "Custom" to
+ "LCS-Telegraphics License"
