+  [ Łukasz 'sil2100' Zemczak ]
+  * Update the enhanced-sb layer model to not preinstall the printing snaps,

+    soon per our staged changes.

+  [ Michael Hudson-Doyle ]
+  * Use a traditional seed.yaml style seed for the canary installer's live

+  * Configure universe sources in canary ISO. (LP: #2033109)

+livecd-rootfs (23.10.23) mantic; urgency=medium
+
+  * i386 foreign-arch support was added for the canary image before 23.04
+    released, but by mistake it was only added to the squashfs for the live
+    session, and not the squashfs layer used as the source for installation.
+    split the chroot hooks to add this to the standard.squashfs.
+    LP: #2033170.
+  * Drop mke2fs.conf override, no longer needed.
