Question about XS-Pro MRC - 203408

There are no pictures of the filter itself and actually little information in the description. Is it the latest version, i.e. B+W 82mm XS-PRO HTC Kaesemann MRC Nano CPL. According to the B+W website, there is now only this version on the XS-Pro polarising filter, but I don't want to find out afterwards that it is an older version. It is also confusing that there is actually also an offer from Digitec for a "B+W XS-Pro Digital HTC KSM MRC nano (77mm, Polarizing filter)", but there is only the option of 58, 62, 67, 77 or 86 mm diameter. Clarity please?
