New Signalling Server and Matchmaker Server connection (Ver 5.5)

Hi

On this new 5.5 version, came a new Pixel Streaming Signaling Server update.

I used to have no issues, using the Signalinserver and the Matchmaker (Ver 5.3), but now Matchmaker server is deprecated, and i cannot connect this Signalling Server new version with my Matchmaker server… is there something that i am missing? some help would be VERY apreciated
Somebody knows anything about how to implement a new Matchmaker, now that it is deprecated?

Thank you very much in advance
