If you are looking for information on all Sim Updates, and all SDK Updates, since MSFS Releases, all in one convenient place, I have been keeping an Unofficial listing on forum.flightsimulator .com..
The advantage of these listings, is that ALL the Update information is in one place, and is easily searchable (CTRL F)
These are READ ONLY lists, so all you get are the UPDATE information, without editorial.
Currently there are 4 lists, and each one has links to the other 3.
Hope you find this the useful reference as I do ......
