Description
The following code has different results in Qt 6.7.2 and Qt 6.8.0:
auto lowerSessionId = QUuid::fromString(u"ca3cf894-5325-482f-a412-a6e9f832298d"); auto higherSessionId = QUuid::fromString(u"fecbea35-08d3-404f-9ec7-2b57c566fa74"); qDebug() << lowerSessionId.toString() << "<" << higherSessionId.toString() << (lowerSessionId < higherSessionId); QVERIFY(lowerSessionId < higherSessionId);
Qt 6.7:
Config: Using QtTest library 6.7.2, Qt 6.7.2 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 14.2.0), debian unknown QDEBUG : tst_QXmppJingleMessageInitiationManager::testHandleNonExistingSessionLowerId() "\{ca3cf894-5325-482f-a412-a6e9f832298d}" < "\{fecbea35-08d3-404f-9ec7-2b57c566fa74}" true PASS : tst_QXmppJingleMessageInitiationManager::testHandleNonExistingSessionLowerId()}}
Qt 6.8:
Config: Using QtTest library 6.8.0, Qt 6.8.0 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 10.3.1 20210422 (Red Hat 10.3.1-1)), debian unknown QDEBUG : tst_QXmppJingleMessageInitiationManager::testHandleNonExistingSessionLowerId() "{ca3cf894-5325-482f-a412-a6e9f832298d}" < "\{fecbea35-08d3-404f-9ec7-2b57c566fa74}" false FAIL! : tst_QXmppJingleMessageInitiationManager::testHandleNonExistingSessionLowerId() 'lowerSessionId < higherSessionId' returned FALSE.

(and same behaviour on macOS on my CI)
My expected behavior is that from Qt 6.7 as that would be the "i;octet" sorting also used in https://datatracker.ietf.org/doc/html/rfc4790.
I think the documentation does not specify which QUuid is using, so maybe this change is legit, however I would have expected a changelog entry in this case.
