Seems CatsXP on W7 and 8.1 exceeded WXP and Vista Extended support number.

If they continues after then CatsXP exceede last Chromium extended support on Windows XP and Vista, Chromium 87 (last normal was 49 + 38 = 87 + 38 = 125

although of course 109+38 is 147, but the difference is in any case larger than between XP/Vista normal and extended XP/Vista,
Which I think is a good point. maybe I'll celebrate it.
