+- Notes for packagers:
+
+  - On recent releases, some external Perl modules including Unicode-UTF8
+    [\#1884](https://github.com/sympa-community/sympa/issues/1884) have been
+    made mandatory.  Check updates on `cpanfile`.
+  - Some distributions including Debian and the descendants separate `perldoc`
+    from the package for Perl.  On this case activating `perldoc` is
+    encouraged for better user experiences.
