|Restricted Differential Revision||rMITK15febaa0b465 Necessary warning suppressions for compiling MITK using Qt 5.15|
I was hoping a bit to include it in the release, if the release would e.g. be used for kaapana containers for a longer time this could be helpful at some point. But of course it's not strictly necessary.
I can understand the reasoning. But adding this feature last minute would basically mean to move the release again and also to test again. And we should realy try to get into the time based pattern.
Additionally, if I have understood it correctly we have currently a crash problem with Qt 5.15, we habe no solution yet and do not know the implication. So just getting this diff through won't really change anything in my opinion. All kaapana containers that need the UI/Qt are still screwed.
Therefore I would strongly opt for keeping it out of the current release branch (as it is a feature) and pack it together with DICOM seg stuff and alike into the next release.
