Package: devscripts
Version: 2.10.61
Severity: wishlist
Tags: patch

Please consider adding an option to update versioned dependencies to
match the new version in case the package depends on another package
with exactly the same version. It would be useful for preserving strict
versioned dependencies between binary packages generated from the same
source.

The attached patch adds such an option and accompanying documentation.
