+libdebian-installer (0.124ubuntu1) lunar; urgency=medium
+
+  * Merge from Debian unstable, remaining changes:
+    - Add more OMAP4 Panda support.
+    - Add OMAP4 Blaze support.
+    - Add Freescale "P4080 DS" and "QEMU e500" support.
+    - src/tree.c: Silence GCC's implicit-fallthrough warning by being explicit
+      in this binary tree rotate code that there's not fallthrough; we're
+      covering all tree rotation cases already (all paths in switch() already
+      return().
+    - Allow to build without udeb packages.
+  * Dropped the following change in favour of explicitly disabling LTO:
+    - debian/rules: re-add the export CFLAGS call to fix build failures on
+      most architectures.
+  * Disable LTO to avoid FTBFS, see #1015482

+  * Package parser: ignore multiarch qualifier suffix (Closes: #1020783).
