+****************************************************************************
+*                   Important Behavior Changes                             *
+****************************************************************************
+
+ - [QTBUG-34345][QTBUG-26008][QTBUG-26430] QPrinter no longer allows you to
+   set an invalid printer name.
+ - [QTBUG-34141] Parsing of Qt::ISODate by QDate::fromString() and
+   QDateTime()::fromString() is not as lenient as before, the date
+   component separators are now required to be non-numeric. This means a
+   string like "2000901901" will no longer be recognized as a valid ISO
+   Date, but "2000/01/01" will still be even though it doesn't strictly
+   meet the ISO format of "2000-01-01".
+

+*                          Library                                         *

+   U+2212.
+ - Fixed sign conversion warnings in code using QMetaTypeId.
+
+ - QTemporaryDir:
+   * Fixed a bug in QTemporaryDir name generator that dramatically reduced
+     randomness of the name.

+
+QtTestLib
+---------

+ - [QTBUG-34630] The (default) plain text logger on Windows now logs to
+   either the system debug log (in case no console is open), or stdout, not
+   both.
+
+QtWidgets
+---------
+
+ - QSpinBox:
+   * [QTBUG-20691] Entering positive values with the '+' prefix is now

+*                          Tools                                           *
+****************************************************************************
+
+configure & build system
+------------------------

+commit proposed upstream.

-    \section3 How to build the MySQL driver for MinGW users
-
-    The following steps have been used successfully for WinXP SP3. In
-    this example, Qt 4.6.2 is shown.
-
-    \list
-
-    \li Download the following components:
-    \list
-    \li \c{MinGW-5.1.6.exe}
-    \li \c{mingw-utils-0.3.tar.gz}
-    \li Qt sources, e.g. \c{qt-everywhere-opensource-src-4.6.2.zip}
-    \li \c{mysql-5.1.35-win32.msi}
-    \endlist
-
-    \li Install \c{MinGW-5.1.6.exe} in, e.g. \c{C:\MinGW}.
-
-    \li Extract \c{mingw-utils-0.3.tar.gz} into, e.g. \c{C:\MinGW}.
-
-    \li Add the path for \c{MinGW-5.1.6.exe} to your \c{PATH} variable,
-       e.g. \c{C:\MinGW\bin;}
-
-    \li Extract the Qt sources, (\c{qt-everywhere-opensource-src-4.6.2.zip}),
-     into, e.g. \c{C:\Qt}.
-
-    \li Add the path for the eventual Qt binary to your \c{PATH} variable,
-       e.g. \c{C:\Qt\4.6.2\bin;}.
-
-    \li Install MySQL (\c{mysql-5.1.35-win32.msi}), customizing the
-       components. Select only the headers and libraries. Install in,
-       e.g. \c{C:\MySQL\MySQL51}.
-
-    \li Open the DOS prompt, go to \c{C:\MySQL\MySQL51\lib\opt}, and run
-       the following commands:
-       \list
-       \li \c{reimp -d libmysql.lib}
-       \li \c{dlltool -k -d libmysql.def -l libmysql.a}
-       \endlist
-
-    \li Open the DOS prompt, go to \c{C:\Qt\4.6.2} and run the following commands:
-    \list
-       \li \c{configure.exe -debug-and-release -platform win32-g++ -qt-sql-mysql
-         -l mysql -I C:\MySQL\MySQL51\include -L C:\MySQL\MySQL51\lib\opt}
-       \li \c{mingw32-make sub-src}
-    \endlist
-    This step takes a long time.
-
-    \li Open the DOS prompt, go to
-        \c{C:\Qt\4.6.2\src\plugins\sqldrivers\mysql} and run the
-        following command:
-        \list
-        \li \c{qmake "INCLUDEPATH+=C:/MySQL/MySQL51/include" "LIBS+=-L. mysql" mysql.pro}
-        \endlist
-
-    \li Now the following libraries are ready in \c{C:\Qt\4.6.2\plugins\sqldrivers}.
-    \list
-       \li \c{libqsqlmysql4.a}
-       \li \c{libqsqlmysqld4.a}
-       \li \c{qsqlmysql4.dll}
-       \li \c{qsqlmysqld4.dll}
-    \endlist
-    To use the SDK and QtCreator directly, copy these libraries to
-    your \c{C:\Qt\...\qt\plugins\sqldrivers\}, and copy
