Dear all, just what I was somehow expecting: I was just launching FS2020, and… an UPDATE is available for download, a little over 1’000 MiB (~1 GiB)!
Release Notes say it’s version 1.12.13.0 - haven’t read them just yet, as I am still starring at the progress bar… dumdidum…
So launch your FS2020 early (as in “right now”), if you haven’t installed the update just yet!
UPDATE: According to the version number that’s the update from December (“SIM Update 2”), so this download probably “just” contains updated navigation charts/data/frequencies etc that get updated on a monthly basis.
But still, be prepared to download and install this update.
