This flag was + used to allow proper alignment of QChar on 2 bytes on older ARM + ABIs, but it also allowed for unaligned access. Qt never generates + or uses unaligned access and the new EABI aligns as expected, so + the flag was removed. + - QTextBoundaryFinder is now consistent with ICU when it comes to + line breaking, reporting the index of the boundary at which the line + break should occur rather than the index of the character. + +QtGui: + - QWidget::setLayoutDirection no longer affects the text layout + direction (Qt::LeftToRight or Qt::RightToLeft) of QTextEdit, QLineEdit + and widgets based on them. The default text layout direction + (Qt::LayoutDirectionAuto) is now detected from keyboard layout and + language of the text (conforms to Unicode standards). To + programmatically force the text direction of a QTextEdit, you can + change the defaultTextOption of the QTextDocument associated with that + widget with a new QTextOption of different textDirection property. For + QLineEdit, the only way so far is sending a Qt::Key_Direction_L/R + keyboard event to that widget. + +QtNetwork: + - Qt does no longer provide its own CA bundle, but uses system APIs for + retrieving the default system certificates. |
