I'm looking for a way to check if forced wipe for server is needed (monthly update on first Thursday by Facepunch is here). I would be grateful if someone would suggest me a way to do this. I could use any algorithm: code sample for plugin to do in game check or script to check it on file level in OS. Also would be just perfect if I also could check if Oxide update related to this also ready.

By needed, I mean that players who have already updated their games will not be able to connect to the server. Of course I know the protocol and even how to get the current version.

I'm trying to find a way to automate forced wipe process. I think I found the solution, but thanks for trying to help and making me laugh xD

Facepunch policy is to wipe all serverson the 1st Thursday (US) which is first Friday (AUS) of every month.
Sometimes it may be a day late but if it is they announce it.
As all players are automatically updated with steam and oxide the server must be updated or no one can join it as the protocol will be wrong,
All RustIO maps are also updated to match the game changes (monument additions etc) so there is no point in using an older map which may have missing additions
