+livecd-rootfs (26.04.23) resolute; urgency=medium
+
+  [ Tobias Heider ]
+  * Fix ISO builds when KERNEL_FLAVOUR != generic.

+
+livecd-rootfs (26.04.22) resolute; urgency=medium
+
+  [ Oliver Gayot ]
+  * Pull the model from Launchpad's lp:canonical-models
+    repo, instead of having it uploaded as part of livecd-rootfs. This
+    indirection makes it possible to update the models without requiring a new
+    upload of livecd-rootfs every time.
+
+  [ Michael Hudson-Doyle ]
+  * Fix two more problems with livefs-built ISOs:
+    - Generate the for-iso squashfs in the right place for Kubuntu.
+    - Fix confusion about the kernel path on the ISO on riscv64.
+
+  [ Tobias Heider ]
+  * Fix pool generation when using extra_ppas.
