apt-listchanges 2.59-0.2ubuntu7 (i386 binary) in ubuntu dapper

 apt-listchanges is a tool to show what has been changed in a new
 version of a Debian package, as compared to the version currently
 installed on the system. It does this by extracting the relevant
 entries from the Debian changelog file, and the NEWS.Debian file.
 .
 It can be run on several .deb archives at a time to get a list of all
 of the changes that would be effected by installing or upgrading a
 group of packages. It can be configured to do this automatically
 during upgrades using apt.
