+ New features [Sean Whitton]:
+ * Introduce dgit.default.build-products-dir git configuration key.
+ Closes:#857316.
+ * Die earlier, and with a more helpful message, if the user tries to
+ include dirty changes when building a source package in split brain
+ mode.
+
+ dgit behavioural changes:
+ * dgit: Always build the source package ourselves, rather than
+ sometimes leaving that to the builder command. dgit will now
+ usually generate *_multi.changes rather than *_$arch.changes.
+ * dgit: Build source packages in a private directory, except when
+ the user passes --include-dirty [Sean Whitton].
+ - dgit push-source no longer cleans the tree [Sean Whitton].
+ * dgit: Rename --ignore-dirty to --include-dirty (leaving the old
+ name supported as a deprecated alias).
+
+ Test suite improvements:
+ * test suite: unset VISUAL, which interferes. Closes:#904308.
+ * Honour DGIT_SCHROOT_CHROOT to set the schroot to use for the sbuild
+ tests.
+ * Support tests/run-all --progressive.
+ * Drop now-obsolete *-asplit tests.
