There is concensus to use non-native version number for updates that
contain only Debian changes. Unfortunately changing back and forth
between native and non-native packages has the potential for
confusion, since the archive will end up with notmuch-0.x.tar.gz and
notmuch-0.x.orig.tar.gz. So we use non-native numbering from the
beginning.
-notmuch (0.6.1) unstable; urgency=low
+notmuch (0.6.1-1) unstable; urgency=low
* Properly install README.Debian in notmuch-vim (Closes: #632992).
Thanks to Jason Woofenden for the report.
