+ * pck-update - Davide Madrisan:
+   Action 4: allow developers to update the distribution-ID when updating the
+   release number.
+   Example: 1mamba --> 2mamba2
+   (when DISTRO_rpm="mamba2" is set in the configuration files).

+-- Update
+
+ * conf/02-specfile-formatting-rules.conf - Davide Madrisan:
+   New default value for 'library_name_structure' ("").
+   The name of library packages has no predefined structure.
+   The previous value ("^lib") was unnecessarily too strict.
