  - added a `make distcheck-light-man` recipe to require verification that the
    manual page files can be built using the prepared "tarball" archive. [#2473]
 
+ - added a `common/Makefile.am` build product for a new internal library
+   `libcommonstr.la` which allows a smaller selection of helper methods
+   for tools like `nut-scanner` which do not need the full `libcommon.la`
+   nor `libcommonclient.la`. [#2478]
