Dear mr Haar,
Thanks for bringing this to our attention.

Hi Erik!
Would you mind to make a change on the OS report page?
I always wondered about values for Linux Mint in comparision to Ubuntu there, and now found the reason in
Clem's blog entry here (see "Wikimedia stats").
What you show as Linux Mint are only those version up to Mint 10.
Current version is 18, and since versio 11, the user agent you (or better let's say "Wikimedia stats") evaluate
is shown as "Ubuntu". There should at least be a note at this line, other distros may be concerned, too.
(Btw., that remembers older browser usage statistics, when websites couldn't deal with Netscape Communicator
so that you'd had to switch the user agent to "Internet Explorer", shifting the usage values complety.)
Best regards,
Dirk Haar
