check for update missing

Hello Musescore-Friends,
I would like to update to the newest version of musescore. I've googled, and it says I'm supposed to find a "check for update"-option either through the "help" or the "edit"-menu. However, I can't find that option anywhere.
I'm using version 3.3.4.9134 on Windows 10, usually in German, but I've also checked with English (UK).
Anybody else has this issue? Maybe even a solution?

Thanks for taking the time!
