Hi Internet Audience,
Perhaps this will save someone a bit of pain in trying to interpret compatibility guides when upgrading ESXi hosts (which is in my near future, and will expound upon posthumously.
Kindly LMK if you have other build #'s to map to Update or Original releases of ESXi and I will add them here. Corrections also welcome, as well please share if you find a link to this sort of table on VMWare.

Caveat emptor! I make no promises that this info is 100% accurate, but it should be darn close.
