Hello!

I can't opt out from beta since i've opted in yesterday.

There is no BETA tab in Fallout 4 options in Steam.

Any ideas?

The version that was a beta the other day is now the live version.

but i still has [Beta] tag near Fallout 4 in games library.

Well, that's strange. That tag vanished on mine when it went live. Can't say I know how to fix it for you, unfortunately.

Well, it's not a real problem, i just want to get fresh updates.

Try restarting Steam. That's usually forces it to refresh.

The only way I found to fix this was to reinstall Fallout 4.

You can make a backup, uninstall and then restore your backup. Voila. No [beta] tag anymore!

Thanks for your tip!

I'll do it when any new update come out.
