Hi,

   "full history" files are kind of a niche interest, but they can be
useful to analyze some things like "how many different people have added
a certain tag", or "how has an object evolved over time", and so on.
They can also be used to reconstruct the complete data set for any given
timestamp in the past (minus, of course, redactions).

I'm happy to announce that the Geofabrik download server now has full
history files for all regions served. These files (called ".osh.pbf")
can for example be processed with the Osmium library and the osmium
command line tool. If you want to run analyses on them without C++
coding, Osmium can convert them to a text-based format ("OPL") that is
then accessible for grep et al.

The full history files will be updated weekly.

Bye
Frederik
