[OSM-dev] release of full-history extracts

Hi all, 

User:Marqqs notified me that some of my .osh.pbf extracts did not
contain visible="false" information and he was right.

I generated the "full-planet-110418-0000.osm.pbf" with the file
extension ".osm.pbf" which advised osmium to drop the visible
information. When I later created the extracts, I used the ".osh.pbf"
extension, advising osmium to add history information. Because the
source did not contain such, it was replaced with the default value of
"true".

I'm currently re-generation those files and try to get them uploaded
tomorrow.

The following files are affected:
europe/france.osh.pbf
europe/netherlands.osh.pbf
europe/germany/rheinland-pfalz/gau-odernheim.osh.pbf
europe/france/paris.osh.pbf
europe/france/nancy.osh.pbf
europe/netherlands/amsterdam.osh.pbf


The following files are fine, they have been converted from
their .osh.bz2 pendents.
europe/germany.osh.pbf
europe/germany/rheinland-pfalz.pbf
europe/germany/bayern.osh.pbf
europe/germany/berlin.osh.pbf
europe/germany/rheinland-pfalz/gau-odernheim.osh.pbf
europe/germany/rheinland-pfalz/mainz.osh.pbf
europe/germany/rheinland-pfalz/woerrstadt.osh.pbf
