+ New features [Sean Whitton]:
+ * New 'push-source' subcommand for source-only uploads. Closes:#848931
+ * When dgit builds a source package, such as in the 'build-source'
+ subcommand, it now bypasses dpkg-buildpackage and invokes dpkg-source
+ directly. This avoids a _source.buildinfo file in the .changes, which
+ doesn't make sense when using dgit. See
+ <https://lists.debian.org/debian-dpkg/2017/06/msg00005.html>.
