+  * dh_translations:
+    - Prevent domain confusion for Meson packages when a help-* domain
+      is present (LP: #1762889).
+    - Don't build help-*.pot. Those templates are used to build static
+      localized XML pages, and we don't want to create LP templates and
+      deal with exported LP translations for such pages anyway.
+    - Allow the domain to be passed to dh_translations via an option in
+      debian/rules.
+    - Strip also Icon and Keywords translations in .desktop files.
