As we know, the Dolphin 7.4 release is a huge mess. 7.4.0 had bugs, so a patch was released to fix them; 7.4.1. Then bam, 7.4.1 had a serious security bug so another patch was released, 7.4.2. Everyone is confused and they do the normal upgrade procedure to find their sites not working licenses removed etc.
It would only make sense to clean up the mess and release a clean 7.4.0 with a 7.4.0 patch. Remove all the mess.
