-  * changelog: start 9.0
+  dgit - low-impact incompatible change:
+  * Drop support for, and testing of, dgit versions which use old tag name
+    (debian/V; now that is maintainer view and dgit is archive/debian/V).
+    The new tags came in in dgit 2.0 in October 2016.  No version of dgit
+    without them was in any Debian release.  We don't expect there are any
+    sites using old servers which do not support the new format, or anyone
+    using a dgit client older than 2.x who cannot upgrade.
+
+  git-debrebase fixes [Niko Tyni]:
+  * Fix `git-debrebase convert-from-dgit-view <upstream>', which
+    would crash due to an argument parser bug.  Closes:#930214.
+  * git-debrebase(1): typo fix.  Closes:#930215.
+
+  dgit - new capabilities:
+  * Support split view with native packages, and with all quilt modes.
+    Now we distinguish "split view" (meaning separate dgit branch) from
+    "splitting quilt modes" (eg --quilt-unapplied).
+    [Prompted in part by enquiries from Sam Hartman]  Closes:#926640.
+  * Support for bare debian/ directory (aka packaging-only) git branches
+    Ie, --quilt=baredebian[+tarball].  [Thanks for info from Shengjing
+    Zhu, and docs and UI contributions/review from Sean Whitton.]
+    Closes:#903392.  Closes:#931253.
+
+  dgit - bugfixes:
+  * Fix --dgit-view-save option alias, which never worked.
+    (--save-dgit-view worked, and still does, though.)
+  * i18n: Do not translate import commit messages.
+
+  dgit - other documentation improvements [Sean Whitton]:
+  * Expand on description of --include-dirty.  Closes:#930922.
+  * dgit-maint-*(7): Suggest --name-status --diff-filter.  Closes:#930956.
+  * dgit-maint-*(7): Using untagged upstream commits.  Closes:#930964.
+
+  dgit - minor consequences of these other changes:
+  * Actually properly reject invalid quilt modes found in git config.
+    (Previously they might be accepted and then cause malfunctions.)
+  * Reject split brain quilt modes with single-debian-patch.
+    (Previously this would malfunction; now we reject it.)
+  * i18n: Add translator notes about ASCII art changes display.
+  * Drop "dgit view: changes are required..." message.
+  * Some other minor changes to quilt fixup error handling.
+  * Changes to debugging output related to quilt modes and split view.
+  * Introduce rpush protocol version 5.  Minimum version is now 4.
+  * Considerable internal rearrangement of quilt fixup code.
+  * Considerable test suite work including new tests.
+
+  dgit test suite:
+  * dgit-repos-policy-debian: Test taint removal.  Closes:#929249.
