+livecd-rootfs (2.664.25) focal; urgency=medium
+
+  [ Brian Murray ]
+  * Add support for creating images (ubuntu-core and classic) with a kernel
+    optimized for Intel IoT devices. (LP: #1938338)
+
+  [ Michael Hudson-Doyle ]
+  * Simplify how the subiquity client is run on the serial console in the live
+    server environment, breaking a unit cycle that sometimes prevents
+    subiquity from starting up at all. (LP: #1888497)
+  * Do not set the password for the installer user via cloud-init as subiquity
+    can now do this itself. (LP: #1933523)
+
+  [ Łukasz 'sil2100' Zemczak ]
+  * Fix sharing of the /dev tree to make sure we can safely umount the chroot
+    when needed. This fixes local non-livefs-builder image builds.
+    (LP: #1938414)
