+partman-base (180ubuntu1mpathpart1) UNRELEASED; urgency=medium
+
+  * init.d/parted: update part_of_multipath() for more recent output of
+    'multipath -l' (actually, no longer expect/match/print the symbols
+    that have changed/may change). This fixes the (incorrect) listing of
+    block devices that are part of a multipath device on partitioning/
+    formatting dialogs.
+  * lib/base.sh: update is_multipath_part() to handle different multipath
+    disk-partition separators ('-part' and 'p'), as recently seen with
+    libparted/parted-server ('p'). This fixes the (incorrect) listing of
+    (non-existent) LVM VGs/LVs for multipath partitions on those dialogs.
