We've got shiny new Relay Servers coming in release 4.5.6. They work better and faster - but unfortunately aren't compatible with our old libs.
Read all the details in our release notes - together with our recommended migration approach:
And note - the old relay servers will continue to work and be available for at least a year. We do highly recommend that you upgrade though!
(PS - We're still in final testing, but the release should be this week...)
As a further heads up folks - it is looking like the 4.5.6 server release may get delayed until early next week. This is to allow us to create a proper mechanism for controlling with specific versions of Lobby Services are active at a time... (right now, it is possible for both old and new lobby services to be active during an upgrade transition - and given how much lobby processing has changed in this release - that wouldn't be good).
That said - the rest of 4.5.6 is ready - so we are going to be doing a bit of an incremental roll-out...
- We are starting to release the 4.5.6 Client Libraries today
- We are also making the 4.5.6 Relay Servers available (on our existing 4.5.5 servers) <- this is a simple feature gate for us to enable.
Then, once the 4.5.6 servers (with the new Lobby Servers and a few other fixes) are available, we will release them... that should be either late this week, or more likely early next week).
Anyway, just FYI...
