Running a very new version in gmod

I was trying to join a server like usual then I get a notice that it is running different tables and I kept trying to run a server and the saying the same version then I notice Im on a very new version of gmod. today 14.02.26.

So there was an update today then. You are going to have to wait for owners to update their servers.

EDIT:Beta update?

no non of my friends have the same update as me

Get off the dev branch.

Thank you code_gs
