debian/patches/0002-Mimic-Version-getVersion-behaviour.patch should be
updated on upgrade in order to provide the actual upstream version.

Starting with 2.3.0, we are merging the signed upstream tags as
upstream, instead of using the tarball that doesn’t ship tests.

# Example to import upstream 2.4.1 version
version=2.4.1
# We still use the upstream branch to drop the .gitattributes file from upstream
gbp import-ref --upstream-tag=%\(version%~%-\)s -u$version --debian-branch=upstream
gbp import-ref --upstream-tree=BRANCH -u$version
