The  data from Swisstopo does not have any "change sets", so importing
them  automatically  would  mean  to  delete  *all* old boundaries and
reimporting the whole new dataset.

But  there is a 'Historisiertes Gemeindeverzeichnis' where all changes
are documented:

The  changes for January (and September 2011) were done manually by me
- in an undocumented but more or less coherent way. :)

Don't mix 'Gemeinde' with 'Ortschaft' bzw. 'Dorf'!

For  all the changes I observed, the old names don't disapear, neither
do the post codes. I created new boundary-relations with admin_level=9
for the former municipalities (admin_level=8).

OpenGeoDB  is  not  maintained  any  longer and consensus is (?), that
these tags can be deleted.
