+Release note  
+============  
+  
+Qt 5.15.3 release is a patch release made on the top of Qt 5.15.2. As a patch  
+release, Qt 5.15.3 does not add any new functionality but provides bug fixes  
+and other improvements.  
+  
+For detailed information about Qt, see the Qt 5.15 online documentation:  
+https://doc.qt.io/qt-5/index.html.  
+  
+  
+Important Changes  
+-----------------  
+  
+### qtbase  
+* 6485b6d45a Fix allocated memory of QByteArray returned by  
+QIODevice::readLine  
+Fixes a regression in Qt 5.15 causing the QByteArray returned by  
+QIODevice::readLine() to consume large amounts of memory.  
+  
+* 5425305597 Update CLDR to v37, adding Nigerian Pidgin as a new  
+language  
+Updated to new version of CLDR (the Unicode Consortium's Common Locale  
+Data Repository) v37. Various Adlam-script locales are dropped due to  
+its use of a number system unsupported by 5.15's QLocale. Support for  
+these locales shall be restored in Qt 6.  
+  
+* f1f650dc3a Deprecate ordering on QItemSelectionRange  
+Ordering of QItemSelectionRange is now deprecated. It was not  
+consistent with equality and should not be needed.  
+  
+* b8518414c3 Deprecate QLocale::Language entries that no locale data  
+relates to  
+Many obsolete language names are now deprecated in preparation for  
+removal at Qt 6.0. No data has been available for any locale using these  
+languages since CLDR v29 (at least; Qt now uses v37).  
+  
+* 9fbc5f1489 Deprecate old aliases for two countries and several  
+languages  
+Deprecated several Language and Country aliases, ready for removal in  
+Qt 6.0, in favor of their newer names.  
+  
+* 1a991e1862 Fix delay first time a font is used  
+Fixed an issue where on some platforms, there would be a delay the  
+first time any font was used, sometimes causing a visible delay in the  
+UI.  
+  
+* 5f935eeed4 Update third-party md4c to version 0.4.6  
+md4c was updated to 0.4.6.  
+  
+* 6d306a0e37 Fix shaping problems on iOS 14 / macOS 11  
+Fixed shaping of default UI font on macOS 11 and iOS 14.  
+  
+* 720304f703 Be more consistent when converting JSON values from variant  
+Restored pre-5.15.0 behavior when converting from numeric QVariant  
+values to QJson* types. Such values now always convert to a double  
+QJsonValue.  
+  
+* bb8522682d Avoid integer overflow and division by zero  
+Pen patterns are restrained to a maximum length and values of 1024,  
+fixing oss-fuzz issue 25310.  
+  
+* c39fd63d71 Return a more useful date-time on parser failure in spring-  
+forward gap  
+Restored pre-5.15.0 behavior when parsing a date-time from a string  
+(and document what it implies): if the string has the right form but  
+represents a date-time that was skipped by a time-zone transition (e.g.  
+a DST spring-forward), the invalid date-time object returned can, none  
+the less, be used to recover a near-by date-time that may be more useful  
+in some cases. From 5.15.0 to 5.15.2 and in 6.0.0, a default-constructed  
+QDateTime was returned in place of this more informative invalid date-  
+time.  
+  
+* 76671a57b5 Containers: call constructors even for primitive types  
+The semantics of Q_PRIMITIVE_TYPE have been slightly changed. Qt now  
+value-initializes types marked as primitive (which, by default, include  
+trivial types) instead of simply using memset(0), which is wrong in some  
+corner cases.  
+  
+* f4152d268e QSslSocket::verify: do not alter the default configuration  
+QSslSocket::verify - do not change the default configuration  
+  
+* cf797c611d PCRE: update to 10.36  
+PCRE2 has been updated to version 10.36.  
+  
+* be0301b42f QString: fix count(QRegularExpression)  
+Fixed a corner case when using QString::count(QRegularExpression),  
+causing an empty match in the last position not to be accounted for in the  
+returned result.  
+  
+* 0ce98b1cf8 Fix qt_alphaVersion and qt_opaqueVersion in the trivial  
+case  
+Opaque pixmaps on devices with a non-standard opaque format will now  
+correctly match format for faster blitting. Same with semitransparent  
+pixmaps on devices with a non-standard semitransparent format.  
+  
+* 6146f4553b SQLite: Update to 3.34.0  
+Updated to 3.34.0  
+  
+* 4cec3ecd2d Change QLineF::setLength() to work whenever length() is  
+non-zero  
+QLineF::setLength() will now set the length if the line's length() is  
+non-zero. Previously, it was documented to only set the length if  
+isNull() was false; this is a fuzzy check, so isNull() could be true for  
+a line with non-zero length().  
+  
+* 39c1c54e0c Fix problems with offset-derived ids for QTimeZone  
+QTimeZone instances created by offset from UTC (in seconds) shall now  
+only include minutes in their ID when the offset is not a whole number  
+of hours. They shall also include the seconds in their ID when the  
+offset is not a whole number of minutes.  
+  
+* 99d3a65cf3 Use design metrics when adding text to QPainterPath  
+Fixed an issue where QPainterPath::addText() would get inconsistent  
+kerning for smaller font sizes when hinting is enabled.  
+  
+* dbaac6e5c1 Remove false Q_UNREACHABLE from shaping code  
+Fixed a possible crash with certain fonts when shaping strings  
+consisting only of control characters.  
+  
+* 6a64b8ed56 Fix crash when requesting A32 glyph on Wayland  
+Fixed crash when calling QRawFont::alphaMapForGlyph() with subpixel  
+antialiasing on Wayland.  
+  
+### qtdeclarative  
+* e203a185cf doc: explain QQItem event delivery, handlers,  
+setAcceptTouchEvents()  
+When subclassing QQuickItem, you should call setAcceptTouchEvents(true)  
+if you need the item to receive touch events. It will be required in Qt  
+6.  
+  
+### qtlocation  
+* 6b1dc419 Allow removal of layers and sources created using parameters  
+in MapboxGL  
+Sources and layers from parameters can be removed
