Thanks for all the info. With your help I was able to obtain older extracts
for Romania and to create some evolution movies. They are not great compared
with what ITO have done in the past but they covered our needs (we have also
contacted ITO, actually Peter Miller, but we had limited time to do this,
and we didn't get an answer in this short period).

I had only one small issue with older planet files: after converting from
API 0.4 to API 0.5 some of the ways had members without ref (something like
this:
 <way id='23312491' timestamp='2008-03-16T11:15:13+00:00' user='Ciprian'
visible='true'>
    <nd ref='' />
    <nd ref='' />
</way>). I have removed these ways and compared the results using 2 versions
of JOSM (one for 0.4, another for 0.5) and the results were similar, so I
move forward. Is this something that is documented somewhere?

If you want to see the results here are some of them:
