How to inform users of old versions?

Is there a way to inform users that they are using a version of bisq that is so old that noe trade will be able to deal with them?

I just wanted to selll some BTC for SEPA and the client told me I cannot start this trade because the other trader doesn’t even have version 0.9x. So it must be some 0.8 version still
or even lower which is kind of ridiciulously outdated.

Is there a way to improve the situation as I think nobody will be able do make a trade with this trader und less specifically installing <v0.9

No, there is only the regular pop up that every user gets when a new version of the software is out.

Maybe that is a good idea though. That users that run really old versions get an extra notice.
