WD My Cloud v3.x, v4.x and v2.x Firmware Versions Download Links

i know, but i was surprised to see that update from May.

as for that update MyCloud unit is not listed to be included!? My Cloud "Authentication Bypass" 09/21/2018

when installing the latest version does this update include previous updates, if ones MyClouds unit misses the last few update fixes? With other words asked: are the updates cumulative?
