Msfs 2024 Marketplace. Msfsmarket.place is an unofficial browser for flight simulator's ingame marketplace. If 2024 comes out and the dev needs to do a bit of work to upgrade it then they should 100% charge an upgrade fee.
Afaik, there has been no official announcement of the date when the 2024 marketplace will open. The interface of the marketplace will show whether content has been created for 2024 or 2020 through labels, giving users an indication whether or not content has been.
