Notwithstanding the fact that one changeset per country would have been better, can I also suggest typing real changeset descriptions when you upload data.

"MAJ OSM diverses le 260825" unfortunately provides no useful information about what and why you edited those objects.  We can only guess that you claim to have surveyed those 3 remote locations today.

By the way, the date is automatically generated in the changeset summary, there is no need to type the date manually in your changeset titles.
