A new version of netpbm-free was recently uploaded to unstable which replaced the libnetpbm9, libnetpbm9-dev, libnetpbm10 and libnetpbm10-dev packages with libnetpbm11 and libnetpbm11-dev packages.
I could not find any evidence of an attempt to coordinate this transition with the release team, nor could I find any evidence of bug reports filed against the reverse dependencies. Since the dev package has also been renamed it seems to me that this transition cannot be performed with binnmus and sourceful uploads of the reverse dependencies will be needed.
