TL;DL: 13 FTBFS left, but those are not libpng's fault. Out of those 13 packages, only 5 are in testing right now.
(I think that's all I can do from my side for now, so I'l pause the efforts waiting for the other parties involved.) Details: The stats are now, and this is the best we can currently get: Built: 474 Failed: 13 OK: 461 The progress is due to the NMU's and the fixing of libvigraimpex, so that its B-Ds became buildable. Still FTBFS are, I've put an analysis why so on the titanpad [1], but those are all _not_ libpng related and many of those packages are not in testing. 3depict blender calligra caret exult fw4spl gmsh libtk-img odin openvrml root-system xemacs21 vtk6 yt There are two packages which are started to fail, due to the accidential transition-required openmpi upload, #813128: vtk6 gmsh Only those packages are in testing: blender criticalmass gmsh vtk6 yt [1] https://titanpad.com/libpng16-transistion -- tobi
