- 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.
