+ltrace (0.7.3-6.4ubuntu1) noble; urgency=medium
+
+   * Merge from Debian unstable.  Remaining changes:
+    - Set architecture to linux-any.
+    - sysdeps/linux-gnu/trace.c: try to make PTRACE scope sysctl more
+      discoverable.
+    - Define _LARGEFILE_SOURCE and _LARGEFILE64_SOURCE in debian/rules CFLAGS.
+      The configure script has a bug where it can't properly cope with the need
+      to define these before detecting the use of elfutils.
+    - Add patch to support arm64.
+    - Add patch to fix ltrace on binaries compiled on recent Ubuntu releases (LP: #1992939)
+    - Include cdbs' autoreconf rules to generate new Makefiles
+    - Add various patches to support ppc64el.

+ltrace (0.7.3-6.3) unstable; urgency=medium
+
+  * Non-maintainer upload.
+  * debian/rules: disabled use of -Werror to avoid a FTBFS in mipsel, alpha and
+    ia64 when using DH level 13. Thanks to Paul Gevers <elbrus@debian.org>.

+ltrace (0.7.3-6.2) unstable; urgency=medium
+
+  * Non-maintainer upload.
+  * Using new DH level format. Consequently:
+      - debian/compat: removed.
+      - debian/control: changed from 'debhelper' to 'debhelper-compat' in
+        Build-Depends field and bumped level to 13.
+      - Closes: #965705
+  * Dropped CDBS in favor of the debhelper to allow the build system to use
+    DH level greater than 11. Consequently:
+      - debian/control: removed no longer needed cdbs and autotools-dev from
+        Build-Depends field.
+      - debian/rules: changed from CDBS to DH.
