+ * Introduce --rm-old-changes to delete previous builds' changes files.
+ * Remove any pre-existing _source.changes file before building source,
+ as a safety check.
+ * No longer tolerate a multitude of .changes files when doing push.
+ Instead, insist on a single one.
+ * dgit sbuild no longer deletes extranious .changes files; instead
+ we rely on --rm-old-changes, or failing that, fail early.
+ * When doing quilt linearisation, treat upstream .gitignores not
+ in the toplevel the same way we treat ones in the toplevel.
+ * When automatically generating quilt patch, honour GIT_COMMITTER_DATE
+ for filename creation (makes filename deterministic in test suite).
+ * New --overwrite option, replaces need to for user to use
+ git merge -s ours. Closes:#838718.
+ * When generating quilt patches from git commits, make patches that
+ look quite like git-format-patch output (rather than strange things
+ based on an obselete interpretation of DEP-3).
+ * When generating quilt patches from git commits, honour (and strip)
+ any Gbp-Pq headers (that we understand).
+ * Several dgit-generated commits now have slightly better annotations
+ from dgit about what it was doing.
+
+ Infrastructure:
+ * Better error handling in dgit-repos-policy-debian.
+ * dgit-repos-policy-debian.: fix git-cat-file-handling with multiple
+ taints in db (!).
