[OSM-dev] release of full-history extracts

[Peter Körner]

Hi

I uploaded another set of extracts. It seems there was a serius bug in 
the old files which were missing the visible-flag in some circumstances. 
This is fixed in the new data-set.

Following some requests I added a South-Africa extract.

All extracts can be downloaded as pbf (and some as xml) from gwdg:
<http://ftp5.gwdg.de/pub/misc/openstreetmap/osm-full-history-extracts/110919/>

Thanks again Eberhard Moenkeberg for his help with the hosting and 
Jochen Topf for his great osmium library!

Peter
