[Apologies in advance for the HTML formatting]
As you may have noticed, the sysadmins were kind enough to generate a
new full history dump over the last couple of days. Besides generating
new numbers for odbl.poole.ch (which will take some time for the full
set), I was mainly interested in seeing how large the effect of
(intentional or not) remapping has been over the last three months.
As can be seen from the following numbers, while the effect is not
particularly large (nobody has really called for aggressive remapping
yet) it is quite noticeable.

Note: both set of numbers (from the 19th of June and the 19th of
September) use the same licensing state data from the 22nd of September.
The "Mappers" row reflect the change in the number of mappers that
created objects that are still visible in the database.
