You can find it in the changelog, in the "Impotant Behavior Changes" section.
http://code.qt.io/cgit/qt/qtbase.git/tree/dist/changes-5.9.0#n35

 - [QTBUG-60771] Reverted a change that caused Qt 5.6 through 5.8 not to
   connect to QSystemSemaphore and QSharedMemory created by running
   applications using Qt earlier than 5.6. Unfortunately, this means that Qt
   5.9 will not connect to 5.6-5.8.
