+ * git-debrebase: scrap works properly when it does only rebase --abort.
+ * dgit(1): Encourage --overwrite rather than --overwrite=version.
+ * test suite: unset GIT_EDITOR, so it works if user has that set.
+ * git-debrebase: Improve laundry performance by a factor of ~55:1,
+ and analysis performance by factor of ~4.2:1. Closes:#905995.
+ * git-debrebase: `prepush' is now a silent no-op if the branch is
+ unstitched. This is more friendly.
+ * git-debrebase: On rebase, always save ffq-prev even if we were
+ both stitched and laundered. Closes:#905975.
+ * git-debrebase: convert-from-*: Snag on patches in d/patches which are
+ not in series, because they will be deleted. Closes:#904997.
+ * changelog: Add close note for #905400 to changelog entry for 6.5.
+ * git-debrebase: convert-from-gbp: Improve messages. Closes:#906641.
+ * git-debrebase: Highly experimental merge resolution support,
+ enabled only with special command line option.
+ * git-debrebase: Check in convert-from-* whether ffq-prev or
+ debrebase-last indicate that we are already in gdr format.
+ * git-debrebase: convert-from-*: leave debrebase-last refs to
+ hint to everyone that this is now a gdr branch.
+ * git-debrebase: Provide hints for unprocessable commits, depending
+ on the apparent branch ffq state, including possible suggestion
+ to use convert-from-*. Closes:#905005. Closes:#905279.
+ * dgit: Mention bad origs as possible cause of quilt fixup failure,
+ in both dgit(7) and in error messages. No longer suggest
+ --quilt=smash or dpkg-source --commit in the error message.
+ Closes:906196.
