QUrl now enforces STD 3 rules: - + * each individual hostname section (between dots) must be at most 63 ASCII characters in length; - + * only letters, digits, and the hyphen character are allowed in the ASCII range; letters outside the ASCII range follow the normal IDN rules - + That means QUrl no longer accepts some URLs that were invalid before, but weren't interpreted as such. - + - The Unix configure-time check for STL is stricter now in Qt 4.6.0. This means some legacy STL implementations may fail to pass the test and, therefore, Qt will automatically disable STL support. - + This is a binary-compatible change: existing code will continue to work without being recompiled.
