The YOG metaserver has refused connection because your Globulation 2 client is out of date.

Happens on latest version from the website on windows.

@progval do you think it could be due to the recent recompilation of the server (see #113)? If so, I'm not 100% sure which commit made that incompatible, probably 9958011, which bumped network protocol for games, and so it could be that the game protocol version is also the one considered for the meta server, although the two are in principle decoupled and I'm vaguely surprised if they would be coupled, but I cannot rule that out and I do not have time right now to investigate that question.

Thank you @progval for the quick reaction! One question: why not using a fixed NET_PROTOCOL_VERSION here (in that case 27)?

I think that in the future we should decouple the meta-server version from the version for playing games over network. I created the issue #118 for that.
