This sounds like a good plan as libdigest-sha1-perl was nevertheless
still widely used. Attached is the patch proposed to apply to the
release-notes.

IMO not the right approach as the aim was really to drop the use of
the obsoleted Digest::SHA1. But adding a release-notes entry is surely
more than worth.

It's a shame this never made it into the wheezy release-notes. I am
closing this bug as wheezy is now too long ago.
