Server sending Versionnumber Support

[maximilianweidenauer]

At the start, the server should send a version to the client, the client then checks if it is compatible with the server, if not an info is shown and the app is stopped.

server now sends serverVersion property to client (applicationMetaData), e.g. 2.0

We should support major.minor.build.revision

build and revision doesn't require a new client
major or minor changed requires a new client

e.g. 2.1.0.0 -> 2.1.1.0 -> client and server are compatible

We also could move the check to the server? Simply send a serverVersion via startup?

I don't mind if the check is on the client, if the versions are not compatible I'm going to show the error-bar with no retry option. I would just need a global variable that has the current working version. How will it be updated? Manually?

[rjahn]

server side check would be the best - for all UI technologies.

Which Server-Version should I send to the Server? 2.0?

[rjahn]

2.0.0

[maximilianweidenauer]

now sending 2.0.0 at startup

[maximilianweidenauer]

Re-open because I haven't added the Error-Message when the Version is missmatching

[maximilianweidenauer]

This is the message I'm displaying. We probably need translation for this?
