Hi again, looking at the code again, it turns out changesets are actually implemented.
I suspect that you are mixing up terminology here. A changeset in osmium, is the collection of metadata about a particular set of data that was uploaded. Changeset information is available in a separate file here: http://planet.osm.org/planet/changesets-latest.osm.bz2 The XML for changesets looks something like that: <changeset id="15449959" created_at="2013-03-22T02:09:28Z" num_changes="0" closed_at="2013-03-22T03:09:28Z" open="false" user="javiarch" uid="1116739"> <tag k="comment" v="pje sargento Cabral"/> <tag k="created_by" v="iD 0.0.0-alpha3"/> <tag k="imagery_used" v="Bing"/> </changeset> You probably want to process OSM data change files from http://planet.osm.org/replication/. These files are normal data files. so you have to process them using the data callbacks node(), way(), relation(). Have a look at the osm_diff_stats.py example, to find out how to distinguish between created, modified and deleted objects.
