Revision control
++ Qt 5.2.1 is a bug-fix release. It maintains both forward and backward
++ compatibility (source and binary) with Qt 5.2.0.
++
++ For more details, refer to the online documentation included in this
++ distribution. The documentation is also available online:
++
++
++ The Qt version 5.2 series is binary compatible with the 5.1.x series.
++ Applications compiled for 5.1 will continue to run with 5.2.

++ Some of the changes listed in this file include issue tracking numbers

++ ****************************************************************************
++ * 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".

++
++ - [QTBUG-35069] Fixed a bug that caused negative number input using '-' to
++ be rejected because the current locale uses U+2212. QLocale::toString()
++ as well as QIntValidator and QDoubleValidator now accept both '-' and
++ U+2212, as well as the locale minus sign. QString also accepts '-' and
++ 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.

++
++ - Accessibility
++ * On Linux action names were returned as empty strings in AT-SPI
++ getActions, now returns the proper names.
++
++ - QKeySequence:
++ * [QTBUG-24406] return Qt::Key_unknown with invalid modifiers on OS X
++
++ - Text:

++ characters from multiple fonts.
