+livecd-rootfs (2.481) UNRELEASED; urgency=medium
+
+  * The target for x86 ubuntu-core images is VMs, so create them with
+    a buffer of free space in order to work if booted in place.
+  * ubuntu-image now produces a manifest file listing the snap revisions
+    used; publish this so that it's picked up by launchpad-buildd.
+  * Change ubuntu-core image builds to use the standard "$PREFIX" naming for
+    artifacts instead of being gratuitously different; requires a matching
+    change to ubuntu-cdimage.
