+livecd-rootfs (2.441.6) zesty; urgency=medium
+
+  [ Robert C Jennings ]
+  * live-build/ubuntu-cpc/functions: Add a function, teardown_mountpoint,
+    to reverse the work done in setup_mountpoint.  Lack of this function
+    has forced users of setup_mountpoint to implement this separately
+    and the implementations have diverged. (LP: #1716992)
+  * live-build/ubuntu-cpc/functions: Remove umount_settle function.
+    The was only used where teardown_mountpoint was lacking.
+
+  [ Steve Langasek ]
+  * Also adjust live-build/ubuntu-server/hooks/032-installer-squashfs.binary
+    to use teardown_mountpoint.

+livecd-rootfs (2.441.5) zesty; urgency=medium
+
+  [ Colin Watson ]
+  * Mount and unmount /dev recursively, to cope with setups where there are
+    interesting bind-mounts under /dev (e.g. loop devices bind-mounted by
+    LXD).  LP: #1716465.
+
+  [ Balint Reczey ]
+  * Fix suppression of kpartx error.  LP: #1684090.

+livecd-rootfs (2.441.4) zesty; urgency=medium
+
+  [ Balint Reczey ]
+  * wrap kpartx and trap spurious errors, to work around kpartx
+    unreliability as seen in autopkgtests. (LP: #1684090)
+
+  [ Steve Langasek ]
+  * Mark autopkgtests isolation-machine since debootstrap won't work in a
+    container.
