Sim Steam 1Gb updated today

Hello, does anyone know what is the last steam update approx 1 Gb i got today?
Thank you all

Development Roadmap - Microsoft Flight Simulator

Thank you for reply, but i still can’t figure out what download was for…

there was no steam update today. Are you opted into the beta?

If you’re not on beta, and you got a download, maybe something got corrupted on your side and Steam decided it needed to fix some files.

No beta for me, still unknow download…
