Control: block -1 by 1089551 1052292 inkscape 1.4 was recently uploaded to Experimental. Unfortunately, it fails to build on too many release architectures. (The release architectures are the architectures with white highlighting in the below link.) This needs to be fixed before we can upload inkscape 1.4 to Unstable.
