| **************************************************************************** |
| * 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". |
