[OSM-dev] Server 0.6 doesn't answer ...

Hi,

and another question: Is there any documentation of the width of the
basic types? I e.g. expect the changeset numbers to increase pretty fast.
Currently we are still quite far from busting the 32 (31) bit space with
the node ids (we are imho somewhere close to 400 million nodes and 31 bits 
is sufficient for 2 billion nodes). 

But the changeset ids may grow much faster and 2 billion updates may be
reached pretty soon. Should we be using 64 bit integers for ids already?
