 - QCoreApplication::translate() will no longer return the source text when
   the translation is empty. Use lrelease -removeidentical for optimization.
 
+- QString and QByteArray constructors that take a size argument will now treat
+  negative sizes to indicate nul-terminated strings (a nul-terminated array of
+  QChar, in the case of QString). In Qt 4, negative sizes were ignored and
+  result in empty QString and QByteArray, respectively. The size argument to
+  those constructors now has a default value of -1, thus replacing the separate
+  constructors that did the same.

 - Qt::escape() is deprecated (but can be enabled via
   QT_DISABLE_DEPRECATED_BEFORE), use QString::toHtmlEscaped() instead.

+- QMetaMethod::signature() has been renamed to QMetaMethod::methodSignature(),

+  * Interpretation of QMetaType::Void was changed. Before, in some cases
+    it was returned as an invalid type id, but sometimes it was used as a valid
+    type (C++ "void"). In Qt5, new QMetaType::UnknownType was introduced to
+    distinguish between these two. QMetaType::UnknownType is an invalid type id
+    signaling that a type is unknown to QMetaType, and QMetaType::Void
+    is a valid type id of C++ void type. The difference will be visible for
+    example in call to QMetaType::typeName(), this function will return null for
+    QMetaType::UnknownType and a pointer to "void" string for
+    QMetaType::Void.
+    Please, notice that QMetaType::UnknownType has value 0, which previously was
+    reserved for QMetaType::Void.
